No other company has come to the rescue with 50-year warp-free guaranteed results utilizing such an array of patented and patent-pending new problem-solving door-building technologies as Sing Core.
Rarely does a month go by where some large door project is presented to Sing Core’s True Flat Team bringing to the table a challenge which has never been seen before. Immediately, the team gets into the lab to find a solution that solves the problems associated with the project at hand.
That’s why architects, door engineers, manufacturers, and millworks refer those tough, seemingly impossible door jobs to Sing Core. Because you not only want the job done right but you want the resulting door to last a lifetime or longer.
This is where Sing and his crack team of engineers with years of experience making the impossible possible comes in handy.
Curved Doors
Another interesting problem that comes up is curved doors, where the curvature of the door must match a curved wall where the new curved door will be installed.
You might think that due to Sing Core’s reputation for spanning large distances while remaining incredibly straight and true that you would assume this not to be a perfect material to create curved doors. Right? Wrong.
Sing Core can be modified to bend to any exact curvature, and once set in place will never misshapen or move and thereby can also be covered by Sing’s 50-year Warp-free Guarantee. It’s that picket fence of patented and patent-pending Sing Core solutions that are making these doors the talk of the town.
These, thin wood framed large French doors and custom curved doors, are just two examples of Sing Core rising to the occasion to make the impossible doors possible, and not only that, but your finished door can also be guaranteed not to warp, bend, twist, cup, or otherwise fail for 50 years. No other method of building a large, oversized door can offer such a guarantee.
One of the most unique design elements in contemporary architecture and design includes the use of wood veneer as an artistic outlet and creative expression as an alternative to solid wood. Doing so increases unique design characteristics exponentially, due to nearly unlimited matching options to create a one-of-a-kind wood grain Objet d’art as a feature presentation piece. Not only is wood veneer just as beautiful as solid wood, but it is a green approach to modern building and design due to the responsible use of natural wood grains.
High-end millworks who specialize in the most exclusive veneer work for the least cost inhibited clientele must have not only the artistic eye but have a keen sense of detail and a great deal of expertise to create one of these masterpieces flawlessly, and they have many methods that they use to assemble and manufacture the veneer while maintaining strength, precision, and to guarantee the overall performance over time for ultimate customer satisfaction.
Woodworkers who take on veneer projects must use a substrate to apply the veneer to. Particleboard and plywood are the most common for general use though they may not meet the needs of more discerning clients. Cabinet-grade plywood and MDO are considered upgrades to particleboard and standard-grade ply. And most upscale millworks prefer the smooth surface of MDF to adhere their veneer to.
When using thin veneers, the smallest imperfections in the substrate are magnified on the surface area, so most high-quality jobs are cross-banded for a more satisfactory and natural overall appearance.
In basic cabinetry and furniture making, these are reasonable solutions for substrate due to there being plenty of reinforcement and supporting structure throughout the piece.
Architects and designers who have experience with creating veneer art realize that there are limitations when using veneer designs when factoring in size. If a piece features a span greater than 8 feet in any direction, many challenges begin to arise when trying to manifest the artist’s vision in the real world.
The most common obstacles to creating large spanning veneer projects, like large doors or conference room tables, are heavy weight, decreased dimensional stability, and increase surface flaws.
Surface flaws become apparent anywhere there may be a seam in the substrate material. Carefully pre-finishing and treating the surface material will conceal the seams upon creation of the piece, but any movement in the piece may expose the seam which will become immediately apparent on the surface area and may lead to delamination of the surface material, resulting in product failure.
The country’s biggest and best veneer artists and architectural door manufacturers know that there is an alternative for veneer projects of large to massive size, and for their most important projects they specify Sing Core as the best wood veneer substrate.
The Best Wood Veneer Substrate
For years, since inventor Peter Sing introduced his patented Sing Core to millworks and high-end large door manufacturers, his veneer substrate has been the flawless answer to the questions and challenges facing architects and designers who have overcome the obstacles to long spanning veneer designs.
This unique hybrid composite core consists of a small (2 to 3 inch) metric torsion box made of vertical wood grain fiber, where the cell voids are filled with rigid foam sandwiched between smooth MDF faces for an incredibly lightweight and dimensionally stable high precision base for veneering.
Sing’s core is so substantial that it sports tolerances of +/- .006 in. and is guaranteed not to warp, bend twist, or otherwise fail (including delamination) for 50 years.
With such a high-precision non-warping substrate, seams will not fail due to movement, and the longevity of the beauty of your creation is preserved over time.
This is the answer that the millworks and veneer shops have been looking for to address the inherent problems associate with large spanning veneer projects for clients who demand the best and will not settle for less.
Therefore, Sing Core is considered the best veneer substrate in the world, and why it can be found inside the most expensive and oversized veneer artistry in multi-million-dollar estates, corporate and industrial projects, museums, and ultra-chic installations.
If your veneer project requires flawless excellence, high precision, and long fail-free service life, you should use the best veneer substrate, so that you and your clients can rest assured because there is Sing Core inside.
Large sliding barn doors are an important feature in the biggest warehouses and industrial locations in the United States, from military to aerospace a big sliding barn door is often specified in the architectural designs for practicality and ease of use. But the larger the door opening the harder it is to keep these huge sliders from warping. If you cannot keep the door straight, you may have reduced access due to door failure.
Ceiling mounted barn doors 14 ft. x 3.5 ft. x 2.5 in.
For years, inventor Peter Sing’s patented warp-free sliding barn door solutions have been the answer to these massive sliding barn doors, which using his patented and patent-pending anti-warp solutions can be built lightweight, high strength, and be guaranteed not to warp for 50 years, unheard of before the invention of Sing Core.

Interior Barn Doors
As interior design has evolved, the integration of interior modern barn doors in everything from residential to commercial projects has seen rapid growth. Of course, standard-sized interior sliding barn doors do not pose much of a challenge, but if the door exceeds 8 feet tall or a 4-foot width, now you are heading into dangerous territory if you are hoping for a non-warping sliding barn door.
Warped Large Sliding Barn Doors
Regardless of the application, large sliding barn doors are going to be problematic, so much so that years ago, the biggest door companies in the USA excluded offering the large barn door from their door schedules, instructing contractors to seek out custom door makers or millworks, because they could not cover these enormous sliding barn doors with any warranty because they were destined to warp and fail not long after installation.
After a while, even the millworks started turning down jobs for large sliding barn doors for the same reason, too many service calls during the warranty period, though this did open a door for door service companies whose job it was to regularly maintain doors, though this was extremely expensive for end user of the warping big sliding barn door.
Not Faulty Design
The problem, it turns out was not with the design, as large sliding barn doors were both stylish and practical, so the architects could not be blamed. The problem is with the limitation in building materials. A dimensionally stable door could be made of a thick solid material such as solid steel, but the bigger the door gets, even solid steel will move according to changes in the environment. Sing is able to bring the ideas of the architects and designers to life in such as way as to provide a 50-year solution to such visionary ideas.
Warp-free Solution
When inventor Peter Sing introduced his warp-free technologies to the large sliding door companies, they embraced Sing’s solutions for warped large sliding doors. Thanks to Sing, they were able to get back into the oversized door market once again. According to them, in their own words. Sing’s core,
“Is the only way to build a lightweight warp-free large door.”
The only way.
A Door is Not a Wall
It is important to learn what the core structure is made of. Doors are not the same as walls. Doors need to move repeatedly everyday while walls are permanently placed. Walls commonly use 2” x 4” framing methods which do not work well for building doors. If the structure of the door is not strong, it will not feel or sound very solid. When you close the door, there will be rattling sounds and/or it can deform over time. It is very easy to tell, all you have to do is close the door and hear how strong or solid the door is made. It may look the same, but it does not sound the same. You can tell the difference by knockings on the door, you can tell what is inside. Solid like a rick but still light like a feather when you swing the door closed. The structure of the door that makes the difference, not the door skin.
You Want a Warp-free Large Sliding Barn Door
We already know you want a large warp-free sliding barn door. How do we know? Because Sing’s email servers are filled with people asking about how they can get a sliding barn door with Sing Core inside? Unfortunately,
Sing Core Does Not Sell Doors
Even though sliding barn doors with Sing’s core inside are among the best doors in the world, Sing’s factory does not build doors. Rather, they provide the raw warp-free base materials to the door building companies and millworks who create the enormous warp-free sliding barn doors, that the inventor is credited with, even though Sing only provides the base material. So, if you really want one, just contact your favorite door builder or millwork and tell them you want a door, “with Sing Core inside.”
What is the Secret?
How to Build a Large Sliding Door
Undoubtedly, you have wondered how does Peter Sing build such large lightweight sliding barn doors that are stronger than steel pound for pound and can be guaranteed not to warp for 50 years? Following are the methods that Sing uses to build warp-free doors of any size, made of nearly any flat building material, secrets revealed.
First, the architect or door engineers, specify the door dimensions and the material that the door will be made of, and submit the specs to Sing’s True Flat Team. The team goes to work, gathering all the data necessary to predict what the challenges will be for the door. Questions like, will it be an interior or exterior door? Will it be exposed to the elements? In what geographical location will the door be installed and at what altitude? Which direction will the door face?
The team starts with Sing’s patented rigid foam reinforced torsion box core, then add additional patent-pending anti-warp technologies to compensate for exterior door skins and environmental concerns.
That is the secret inside these huge warp-free doors.
How Can You Ship Such Large Doors?
Of course, the military can do amazing things with transportation that cannot be accomplished by mere mortals, so Sing has created a modular technology that supports his 50-year guarantee. In this manner, any size of door can be built and shipped in high precision sections that are assembled on-site.
Joining a modular door shipped in sections
This saves so much on shipping and handling costs, and if the large door needs to fit in an elevator or tight doorway, not problem. High precision modular solutions are the answer. Sing Core has built many large doors that are joined on-site without any warping.
Don’t try this at home. Average dowels and even larger biscuit-joining will not prevent door warping. Let’s say you wanted to build a pair of 10’ x 20’ double barn doors that were 2-inches thick. Stacking and joining four 5’ x 10’ x 2” panels together will not be an easy task. But Sing Core has had many years of experience with oversized doors, and has been devoted to solving the common issues with larger modular doors.
If you have a good budget, high precision demand, and no issue accessing the job site then a one-piece large door panel is the way to go, if it can be shipped to your location.
Otherwise, modular door sections joined on-site will be the best option. There are two major factors to achieve high quality when building large doors. One is to make sure there is no warping once the modular sections have been joined. The second issue is maintaining a high precision joint line so that it is not noticeable. This requires a very high precision core to achieve. Sing Core is the most precision door core available, with a tolerance of ± 0.007”. It is important to be sure that the thickness of the core is within these tolerances.

Weight and Strength
Strength plays a key factor when building larger doors. Traditional door building methods may dictate that strong doors are heavy and lightweight doors are weak. Weight is a major issue with oversized doors. Heavy doors are significantly more expensive due to additional structure costs, higher labor costs, and extra shipping and handling costs. Heavy door core does not mean that it will have high strength and the larger the door is, the more strength is necessary to maintain a long lifespan.
What type of skin is best to build a large modular door?
Paint Grade – It is easy to hide the seams. Seams can be almost unnoticeable if modular sections are joined with a Sing Spline. If the spline is made of solid wood, it can move or warp after the moisture levels change and it will be reflected on the surface of the door. This can cause the surface of the door to crack after the seasons change.
HPL (High Pressure Laminate) – See how precise the joint is using only a Sing Spline. HPL is available in a wide variety of patterns. The best choice for HPL is a vertical pattern to help the joint blend into the surface. HPL is a good choice when ordering one of our modular oversized doors. The patterned HPL allows the joint line to be hidden in plain sight. The door can be as big as 12 feet tall and 40 feet wide without having any noticeable seams.
Metal – If it is paint grade metal, the seam can be filled with joint compound and then painted making a seamless joint. Metal doors are traditionally very heavy, but with Sing Core inside your metal door can weight roughly 1/3 of a traditional metal door. You can choose from any type of metal you would like, but our most commonly made metal doors are Aluminum or Cold-Rolled Steel. Click here to see a paint grade Sing metal door.
FRP – FRP, or Fiber-Reinforced Plastic, can be used to make very large doors and very durable doors. FRP can be smooth or have a textured surface. It is much more visually appealing and functions much better than solid wood which has potential to crack, warp, twist, and cup. Besides, solid wood weights a lot more than Sing wood stave planks. Sing wood stave planks are the ideal material to replace solid wood for such jobs as, doors, tabletops, post and beams, and many more. An advantage of choosing wood staves are that they are much more precise than solid wood because their tendency to move over time is minimal in comparison. On the other hand, wood staves are much harder to match with surrounding patterns than a wood veneer skin.
Wood Veneer – Wood veneer has an average thickness of 0.020″-0.030″ and is very difficult to hide joint line in the face of the panel. Wood veneer is often much more challenging because it is usually very thin, normally only 0.020” thick. We always suggest using thicker wood staves which are usually 0.125” thick rather than veneer. However, Sing Core has a proprietary technology to make a veneer panel seamless as large as 10′ by 16′. This requires the veneer to be staggered and hot-pressed. It is very costly to use veneer, oftentimes we use wood staves to build larger doors.
For a tighter budget, we recommend using a paper backed veneer which only requires being cold-pressed. Sing Core provides the smoothest MDF skin for our clients to hot-press. Cross banding is not required with our smooth and high precision substrate, which may be hard to believe for some people. We have been doing this for many years with our innovative technology. We always recommend that our clients purchase our veneer substrate, complete with the same warp-free guarantee, and hire your local veneer contractor or do it yourself to save some money. One advantage to using a wood veneer as the skin for your door panel is that veneer can be easily matched to the surrounding area. One disadvantage to using wood veneer skin is that it is not well suited for exterior purposes, such as entrance door, and it can be difficult to repair if damaged. Veneer skins are the also limited to the maximum door size of 10′ by 16′.
Medium-density fibreboard (MDF) is a popular material, especially because it can be precision sanded and remain very smooth which is an excellent surface area to treat, paint, or apply other materials, anything from vinyl and Masonite® to natural wood grain and metals. The upside to this material is wide open, while the downside presents a challenge.
The biggest problem with MDF is that it is not very stable or strong. The phrase we hear commonly is, “we love it, but it warps like…” (add expletive).
Patented Sing Core and our warp-free technologies enable us to provide millworks and artisans with a high end MDF surfaced material which is lightweight, high strength, and extremely dimensionally stable. Now, you, too, can have the highest grade MDF in the industry to use in your most important high precision projects without risk of failure.
This technology moves the smooth surfaced material which can easily be high precision sanded to a whole new level!
That’s why you find this revolutionary newly invented patented and patent pending warp-free technology atop the tallest building in the United States of America.
Now you can have a warp-free large MDF panel which our clients use to apply almost any laminate surface because it is so smooth, and you can even apply natural wood grain, and it can still be guaranteed not to warp, bend, twist or otherwise fail for 50 years.
Sing Core is the secret weapon used by the top millworks, large furniture designers, and the biggest and best door companies, to keep their MDF straight and true.
It is not uncommon to find Sing’s patented MDF-solution inside the most prestigious locations around the world and from beneath the sea (US Navy) to outer space (NASA) and everywhere in between.
In fact, this is the business arena where patented sing Core shines: If you have a problem keeping it straight, inventor Peter Sing’s core and his True Flat Team can provide you with a rock solid hybrid composite core covered heel to toe in MDF which can be guaranteed warp-free for 50 years.
No other Eco-friendly lightweight material can achieve such feats.
SingCore has very little deflection over a 20′ span:
Even though Sing’s patented insulation reinforced vertical grain torsion box core is often compared to honeycomb core materials, it’s plain to see that no other lightweight honeycomb core material can compare.
Whether Sing’s core is used as substrate inside panels, posts, and beams, or as warp-free door core, you will find architects, designers, and engineers empowered by having access to the most revolutionary building material which is changing the way things are made.
That solution is Sing Core MDF, the highest grade MDF in the industry today.
We at Sing Core are so fortunate to support the arts by providing museums and galleries with the best Eco-friendly museum displays and art display materials in the world which are capable of protecting sensitive works art.

Our Master Quality Doors are Complimented by Our Ultra High Quality Skin and Surface Choices
Wood Veneers
Veneer allows us to create a high end finish with less weight and cost while offering a wide assortment of beautiful door surfaces. There are a number of different types of veneers that all provide excellent options that will compliment the styles of your structures. Difference species generally demand a different price. Some popular examples are Maple, White Oak, Mahogany, Cherry, Alder, and Hemlock. Veneers are sold in bundles and range in price, but generally use the most flawless wood to provide the absolute most appealing visual aspects for your doors. Standard veneer thickness is .020″, and is often used to decorate high end furniture, cabinetry, cabinetry, floors, and even plywood. You can trust Sing Core to veneer your doors, alternatively you can get substrate only and have your veneer applied locally.*
The beauty of veneer is the high quality wood grain appearance that provides you with the most natural aesthetics. Each piece is completely unique, because it is cut from the actual logs. Not only does this allow you an amazing modern appearance, but also you can achieve a more vintage, timeless, or antique look. Normally, better quality veneers are used for doors, because customers want the best looking doors they can possibly get. Door grade veneer comes in a few distinct grades.

Face Cut Options
Rotary Cut Veneer – Created by spinning the log and peeling off sheets, almost like unrolling a roll of toilet paper, rotary cut veneer is the most common type of veneer. The advantage of this type of veneer is that it results in one continuous sheet. It is a very cost effective way of producing veneer, but it results in a very unpredictable grain pattern.
Plain Sliced or Flat Cut Veneer – This is the second most common cut. In this method, thin layers are sliced one at a time along the width of the log. The slices, which are also called leaves, because the blade works its way from the top of the log to the bottom, there is a gradual transition in the grain pattern. This method of cutting parallel to the growth rings results in a V-shaped pattern that is often seen on sheets of plywood.

Hard Maple
Rift Cut Veneer – Another interesting method is the rift cut process, which allows for a more straight-grained look. In this method the log is quartered, then cut perpendicular to the grain in repeating arches. The advantage to this is that you get a relatively uniform grain appearance. The disadvantage to rift sawn veneer is that it costs more, because the process is more time consuming.
Quarter Sliced Veneer – This type of veneer is also sometimes called quarter cut or quarter sawn veneer. This cut is often specified when the customer wants an exceptionally straight grain appearance. First, the log is quartered, which allows each quarter to be sliced perpendicular to the growth rings. Since leaves are cut more narrowly than plain sliced, they are much more easily lined up with other leaves, allowing for superior uniformity. Despite it’s vast advantages, this method requires a larger log diameter compared to the alternative methods. This method also achieves a sort of flaking appearance, created when the veneer knife bisects medullary rays in the tree.

Veneer Matching Options
No matter what cut of veneer is applied, without proper veneer matching, your project will not turn out as expected. Veneer matching is a true art form. The job of matching veneer is a precise job that requires a detailed approach. The appearance is partially determined by how the veneer slices are lined up on the doors.
Book Match Veneer – Every other veneer leaf is turned over, like the pages of a book. With this method, the veneer will be mirrored between each consecutive two leaf section, resulting in a repeating series of symmetrical patterns. This method is preferred by many, because of the continuity of grain. This method produces both ascending and descending prominent characteristics of the grain. Not all cuts of veneer can be used with the Book Matching method, however, but plain, quarter, or rift sliced veneers can all be used for this purpose. This book end formation tends to reflect light and accept stains differently. With this method there is also potential for wide color variation, known as “barber pole” in some species or flitches. Despite these variations, they are still considered desirable.
Random Match Veneer – This method produces a more chaotic appearance, because pieces are generally unmatched, as if the applicator has taken a series of boards and lined them up on the surface of the door. This produces a more old fashioned look, as something that was perhaps built before modern methods of veneer were invented. With this method, there is often a deliberate method to reduce grain consistency.
Continuous Match Veneer – This is when the pieces of veneer are used for both the door and the transom, allowing for a very consistent look between the door and the transom.
End Match Veneer – This is generally selected for doors with transoms. This match uses a single piece of veneer that runs from the bottom to the top of the door. Veneer can be turned turned at the joint to achieve this appearance.
Slip Match Veneer – This is one of the quickest methods of matching veneer, but requires higher quality veneer that is fairly uniform in appearance. Sheets are slipped out on the the surface one after the other, creating a wave of repeating patterns. Some frown on this method, because of the abrupt joints. This differs from book match veneer in that book match is better at hiding the joints. Uniformity of color is superior in this method, because each piece has a similar level of light refraction. It also allows for a relatively straight grain pattern.
Blueprint Veneer – is sequential veneer from a single source to cover an entire area. Complete rooms are the most impressive when they are blueprint veneered. Some jobs include matching blueprint door skins as well. Proceed with caution, making sure there is enough source material to complete the job, and there is no room for mistakes.
Natural Variations
Because wood is an organic product, each piece has its own characteristics. There is a vast array of grain patterns and formations, which can vary among trees and different flitches. Because of that, some trees may not meet standards. Other trees may considered of exceptional quality. Prices may also vary depending on the quality and appearance of the veneer. Because of variations in natural grain of each tree and differences in cuts, you can experience amazingly unique grain, pattern, and color, for each leaf of veneer, which translates into an an unlimited variations in door appearances.
In all cases, the natural wood quality will improve and compliment design elements, especially if the wood is applied in its natural state, unfettered by paints and enamels which might hinder the actual beauty of the wood.
Some species, like maple and birch can show a wide variety of color ranges. When it comes to maple and birch unlimited amounts of sapwood and heartwood, large portions may be unusable, because of unacceptable color. Sapwood lighter in color, while heartwood is darker in color. There is also the issue with light, dark, and color streaks, spots, and color variation that results from mixing sapwood with heartwood. If these sorts of variants in color and grain are not desired by you or your customers, veneer must be selected accordingly. If lighter shades of veneer are desired, you must specify sapwood maple or birch. If darker shades are required, you should select heartwood, however, this type is often limited in supply.
* = Professional veneering can be very tricky. If you are getting substrate from Sing Core and having your millwork (or someone else) apply the veneer, be certain to affirm that they have the expertise to apply the veneer appropriately. We use the highest level of professional veneer professional and techniques. We can guarantee our veneering, if you have veneering done off-site, it is their responsibility to do it correctly. A faulty veneer could jeopardize your Sing warranty.
Door Graphics and Murals
Our doors make an exceptional surface for applying murals, canvases, or printed wraps and images. This is an excellent way to make an otherwise standard looking door, beautiful and vibrant.
In recent years, graphics, scenes, or photos applied to the surfaces of doors that turn your openings into true works of art. This style of door is only limited by your imagination! Some examples are as follows:
Fine Art: Amazing portraits, scenery and landscapes, animals, objects like cars and still life images
Designs: Patterns, colors, shapes, and other abstract art
Wood Grains: Any sort of wood species, style, or colors
Plants: Beautiful flowers, leaves, barks, and other plant based imagery
Textures: Pebbled, rusted, grainy, smooth, baked earth and other textures
Other: Anything you can imagine can be printed Sing Core doors as long as you have high quality electronic images and graphic files.
We start with a smooth tempered board or Medium Density Overlay (MDO) for a best quality finish, or select a wood veneer or paint grade option for your highest quality finishes. This is only limited by your imagination!

Customer Review: Joe Ballweg
⭐️⭐️⭐️⭐️⭐️ (5/5)
*”I needed a large (10′ x 7′) pocket door fabricated for an art studio renovation that would not warp or be too heavy to maneuver. SingCore worked with the project’s budget to make their product practical. I appreciated the work Ivan did to ensure that the shop drawings were clear and met all the requirements for the installation.
Our door was shipped in 2 panels and I was given instructions regarding unpacking and joining the panels. Ivan was also helpful in offering advice on how to deal with receiving the 650 lb crate without a loading dock and with minimal help.
The process of joining the panels was involved and some preparation was required, but I asked many questions and they were all answered thoroughly and helped with the entire process. I wouldn’t hesitate to use SingCore again or recommend them to anyone needing a large stable panel.”*

Lightweight Yet Solid Modular Door System
First of all, Sing Core panels use our patented honeycomb core. This unique core is designed to be ultra-light while maintaining the solid feel of a traditional wood or metal door.
Even oversized doors become easy to move and install. In many cases, a single person can handle the door without special equipment. This reduces labor and makes every job easier.
In short, you get a door that feels solid without the weight that slows you down.
No Warping—Guaranteed for 50 Years
Warping ruins doors over time. It causes misalignment, poor sealing, and eventual failure. However, our Modular Door System completely solves that issue.
Each panel is guaranteed to remain warp-free for 50 years. That’s right—five decades of guaranteed performance. You can install massive pivot doors, custom sliders, or tall entry doors with full confidence.
Because the system is built to last, you won’t face costly callbacks or repairs.
Unlimited Sizes and Endless Options
Traditional doors are limited by material size and weight. In contrast, our modular design removes those limits. You can build doors as wide or tall as you need by connecting multiple panels.
Furthermore, the system works with almost any type of door: curved, pivot, sliding, or folding. This makes it ideal for unique designs and oversized architectural features.
Plus, every door is built to order. That means you choose the finish, edge banding, core options, and more. Whether you need fire-rated skins or soundproof cores, we’ve got you covered.
Easier to Ship and Faster to Install
Large doors often come with big problems during shipping. They require custom crating and oversized freight. Thankfully, the Modular Door System avoids all of that.
Instead, we ship each door in compact, lightweight panels. These smaller sections are easier to handle, store, and transport. This helps reduce freight costs and project delays.
Once on-site, the door panels connect using a concealed alignment system. The result is quick, accurate assembly that saves time—and eliminates frustration.
In Summary: Sing Core’s Modular Door System delivers strength, flexibility, and efficiency. It solves common problems faced by architects, builders, and contractors—while opening up new design possibilities.

Sing Core and James Abke Turn Mercedes Van into a Portable Home
James Abke is a professional of the highest caliber who is also an avid traveller. He needed the best accomodations for his extended trips in his Mercedes van. Because of his unique needs he sought out a unique company who could do something which, in most industries, is normally called “mission impossible.”
James chose Sing Core because of our proven track record of providing the most unique products that are designed to perform under the most extreme conditions. Mr. Abke needed materials to build his special luggage rack and bed in the back of his Mercedes that would allow him to eat, sleep, and work in his van.
“The panels are awesome…I have a feeling they will last a lifetime.”
-James Abke

This job required a material that would be extremely strong, rigid, with virtually no flex, yet light weight. James Abke knew this was something almost no one could do. That is why he approached Sing Core, Inc.
The Force Behind Sing Core
Under the supervision of Master Inventor, Sing Core Founder, Peter Sing, we got right to the task, designing this system for maximum performance and lighter weight. Using our patented and patent pending Professional Sing Panels. Sing Core is the best product on the market for these types of applications, because our core is stronger, tested independently in UW labs to be able to withstand 660 PSI of force, up to 90% lighter in weight than solid wood, more versatile, and more visually appealing than any other product on the market.
Because Mr. Abke required only a 1” thickness on his panels, he could not use just any material. He needed the strongest, lightest weight material he could possibly get ahold of. These panels had to be stronger than steel to endure the punishment he had planned for his Mercedes van conversion. This configuration required that the system be able to hold up several hundred pounds of weight without showing any signs of stress. These panels also offer much more insulation and sound blocking capabilities than solid wood or hollow core panels, thanks to Sing Core patented and patent pending technologies.
See how small these panels fold up! They are barely noticeable once folded for storage, and they are completely out of the way, thanks to James Abke’s implementation. This design allowed him to fold down the panels so he could use them as storage or else move them to the side and use the full space in the back of the van for cargo.No oneelse can do this.
Multi Purpose Design
James Abke was driving across the country in his van when he got the idea to do the unthinkable. Because of his unique need for a system that would allow him to work, sleep, as well as, store luggage in his van he designed a system that would be able to accommodate all three.
“I worked with several Singcore agents to find a solution and came up with a panel that I was able to coat with a truck bed liner (Rhino-Liner) in order to make the panels nonskid and very durable.”
-James Abke
The icing on the cake was that Mr. Abke’s design was able even able to accommodate a bed. Because of the ultra high strength, lightweight, warp free quality of Sing Core, James Abke was enabled to design a system that could easily accommodate two people, 500 pounds with no difficulty at all, without any compromise at all to the integrity the structure. Having a bed in his van allowed him to sleep on location, anywhere.
This was the perfect application for our products.
“It was imperative to me to have light weight panels strong enough to hold two people (for camping mode) or heavy equipment (in work mode) and be thin enough to be able to be stored inside a rather compact cargo van when they were not in use.”
-James Abke
James Abke’s design was simply one of the ways we can do this. The possibilities are only limited by your imagination. We can even make drawers or other additions that can give you better storage options than you ever imagined. For this sort of application that requires such precision, high strength, light weight, and warp free character. Sing Core is the only solution for this type of situation.
We do not make SIP panels. SIP panels will bend, break, twist, and crack. They are made very cheaply with Chinese materials. Our panels are made from the absolute best materials. They are made 100% in USA, using materials sourced from the USA.
James Abke’s new system can hold huge amounts of luggage. Sing Core technology allowed him to have more than one layer of storage in the back of his van. With our technology, we can manufacture panels that are stronger, more durable, lighter in weight, more warp resistant, available in more skins, with more bells and whistles. Moreover, they come in any size, larger than any other panels on the market, they are more visually appealing, and come with many more features. Not to mention, they are the only panels on the market that come with a full 50 Year Warp Free Guarantee. They are 100% made in America, using materials sourced from the united states.
Sing Core is celebrating our continued expansion which is taking us to new places and new opportunities for you to experience what it means to have Sing Core inside your high-end products using our new, improved simple pricing method.
This pivot door represent the best reasons why Sing Core excels in these types of applications. Our light weight, yet strong core technology lends itself perfectly a functional and resilient door. Clients will find their Sing Core pivot door easy to use, and not too bulky, but still with a strong feeling like steel in their hands.
