Sing Core specializes in increasing the performance, durability, and customer satisfaction in high-end veneer work in custom veneer doors of any size which can be guaranteed to remain warp-free for 50 years, including full structure warranty. No other method of manufacturing a large high-performance veneer door can achieve these results.
It all starts deep within the structure of any veneer door with Sing Core inside. Sing Core is the patented brainchild of inventor Peter Sing who conceived of the structure core which revolutionized the way doors were made.
Sing’s invention is basically a vertical grain torsion box core with small grid structure where the grid voids, which are usually left open in traditional torsion box, are filled with rigid foam insulation.
This composite base material is pressed between to stress skins to create Sing’s lightweight high strength high-end veneer door core.
The biggest and best door companies, millworks, and custom door manufacturers love it, and you will find them using Sing Core inside all their high-end custom large veneer doors. And that’s why you’ll find them at the top of the tallest building in the United States of America, World Trade Center 1‘s Freedom Tower.
Telegraphing and Crossbanding
The most environmentally conscious way to create a veneer door is with a thin veneer material, such as 0.020-inch veneer. The only problem with this thin veneer is telegraphing.
It is normal to crossband veneer, which basically doubles the price of the veneer, to prevent telegraphing.
Not necessary with Sing’s super-smooth veneer door blanks. He uses his patented veneer door technology to create an extremely smooth surface to lay veneer on flawlessly by using a thin later of MDF to accommodate the lamination of a thin veneer.
Problem solved.
Large Oversized Veneer Doors
When architects spec an architectural veneer door, if it is a very large door (anything over 8 ft tall or 4 ft wide) they are far better off going with a thin wood stave surface. Wood stave consists of wood planks cut into thicknesses of 1/8 to 1/4 -inch thickness. Then this solid wood is applied to Sing’s door blanks.
Veneer is normally limited in available lengths, whereas planks of specific wood species are generally available in longer lengths. This can accommodate the long length necessary for a vertical grain veneer door design.
Plus, if it’s done right, your high-precision large wood stave door with Sing’s core inside looks just like a solid wood door. Only it weighs far less than any other solid core door, and can be guaranteed not to warp, bend, twist, cup, or otherwise fail for 50 years.
And no other door can come backed with such an impressive guarantee.
Even though Sing’s doors are desired by nearly everyone, to have such a door may be cost-prohibitive for most. It is more common to find high-end veneer doors with Sing Core inside in the most expensive homes in the USA. You may find them used in scientific research, and anywhere in the world, from beneath the sea (US Navy) to outer space (NASA) and anywhere in between.
Once you’ve experienced a high-end veneer door of such magnitude, you will agree with the professionals who insist on using Sing’s patented solutions, that,
“It’s the only way to do it.”
Sing Core is the only way to build a big veneer door that can be guaranteed for 50 years. The only way.
Veneer doors are the most responsible use of natural resources because the declining supply of available natural wood grains are mediated by slicing very thin layers of grain into sheets of natural material which can be applied to a flat surface, such as plywood, panels, or used as door skins.
Most Popular Veneer Doors
While the various wood grain varieties of doors change, some veneer types are more popular than others around the USA. Right now, the two most popular wood veneer doors are,
Walnut Veneer Doors and Oak Veneer Doors
Walnut and oak veneers are tied for first place in the world of veneer doors, followed by maple, birch, teak, mahogany, cherry, ash, cedar, and pine veneer doors, in that order.
A veneer door is indeed beautiful, but this elegance is only skin deep. The attributes of the veneer door’s underlayment are the key which greatly enhances or diminishes the appeal of your veneer door, which is the best predictor of your veneer door’s performance over time.
Veneer is an excellent way to build a standard-sized door, but when you are reaching for door heights which pass the 8 foot mark or widths that are greater than three-and-a-half feet wide, you start running into the risk of door failure.
Even if you run into a problem with a standard sized door, it’s not too much of a problem, because factories (most offshore) are churning these out by the thousands every day. So, when your door fails, you just run down to your local hardware store and buy an inexpensive replacement door and you are back in business. This is often less expensive than hiring a millwork to service or repair your veneer door.
Large Veneer Door
Large veneer doors are an entirely different animal. These oversized doors do not come off of a conveyor belt. They are usually a one-off build by a highly skilled artisan or team of craftsmen who are building these big veneered doors according to engineered architectural specifications.
There are many things to take into consideration for a large door with a natural wood veneer on it. The first consideration is the veneer, itself. How thick is it? What will the substrate be made of? How will it be applied to the substrate. If, laminated, what is the method used, what adhesive will be applied, and how long will the lamination last, before it starts to delaminate?
Wood veneered doors are more commonly used indoors, as the thin veneer is not well-suited for exposure to the elements, such as in a large front door application. In this case, you would be better off using a thicker surface material such as an eighth to a quarter inch-thick wood stave skin (planks) for exterior doors.
Most importantly, you want to pay close attention to how the door will be made from the inside out, especially in large veneer doors over a standard 3-0 7-0 door? Why? Because they will warp. Almost any material used in building an oversized veneer door will move according to variations in the environment where the door resides.
I say, “almost,” because there is one way to build a large veneer door that will not warp.
Warp-free Veneer Door
If there’s one thing that the high-end custom veneer door manufacturers know, it’s that if it’s large and, “If it doesn’t have Sing Core inside, there’s no warranty.” Why? Because all large veneer doors move. That is to say, they warp, bend, twist, or delaminate, because they do not have Sing Core inside. All due to the movement of the door over time which breaks down all the necessary components and compromises the operation of the door.
Thanks to inventor Peter Sing’s invention of his engineered composite hybrid warp-free veneer door core, doors can be made to remain straight and true for years to come. They are also the lightest weight strongest (stronger than steel pound for pound) door blanks in the world which are also fully insulated for added sound deadening and climate control capabilities.
Even though Sing says, “We do not build doors,” he is responsible for some of the biggest most beautiful doors in the world that deliver the highest precision (Sing’s core boasts +/- .006-in. tolerances) most sustainable doors in the world with unsurpassed longevity. Each door with Sing’s core inside can be backed by Sing’s unprecedented,
50-Year Warp-Free Guarantee
This is the truth. Sing guarantees his doors to remain warp-free for 50 years. He has been providing the biggest and best door companies in the nation with warp-free door core. And if you ask these door companies, “Why?” They answer,
“There’s no other way to do it.”
There is no other way to build a big veneer door that will not warp without Sing’s core. That’s why we rely on Peter Sing’s invention to deliver the goods. And, as Sing says, “If it wasn’t true. If I couldn’t do it, even once, I could never offer that guarantee again.” And he’s still here without even one warped door in ten years.
How do you get Sing Core?
Increasingly, Architects are specifying Sing Core in all their high end essential large door projects. But if you want one, all you have to do is to go to your local millwork or large custom door manufacturer, and tell them what you want, but be sure to tell them, “I want Sing Core inside,” and leave the rest up to us.
It takes a village to build a large veneered door.
Architects and engineer’s work on the concept and the design, then there are the door companies and millworks who are responsible for the hardware and finishing aesthetics, and finally fine craftsmen hang and install the door.
Your veneer door with Sing Core inside is a one of a kind work of art.
That’s why you find Sing’s core in the tallest doors in the tallest building, on the top floor of the Freedom Tower at World Trade Center in New York, and anywhere from beneath the sea (US Navy) to outer space (NASA).
If you approach the most prestigious millworks in the world and ask them how to make the best high-end veneer doors in the world, you are likely to receive a response which references Peter Sing’s patented and patent-pending veneer door technologies and his Master Quality Door Veneer Surfaces.
9 ft Tall Oversized Exterior Walnut Veneer Door 50 yr Guarantee
Wood veneer doors are growing in popularity due to the design features which are available in matching grain orientation on the faces of the door. The most popular orientation is called “book match” which orients leaves of veneer opened alongside each other in alternating pairs, like opening a book, where the left leaf mirrors the leaf on the right.
Book matched veneer doors are followed by “slip match” veneer doors, where the grain orientation of the leaves all face the same direction alongside one another.
There are other types of veneer matching which includes “end match,” where veneer leaves are mirrored end to end, “reverse slip match” which alternates veneer strips flipped end to end, which greatly reduces any mirroring effect, producing a more natural result. “Random match,” which shuffles all the pieces and creates a more unique succession of veneers placed side by side.
Then, there is “blueprint” which 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.
Beyond these veneer matching options; special matches can be made to create a desired artistic result for high-end architectural veneer doors.
These matching capabilities are unique to veneer because veneer is sliced so thin that there is grain duplication which can be matched or mismatched according to an artist’s or designer’s vision.

Veneer Door Problems
When tasked with bringing a veneer door to life, the production team can run into problems associated with building veneer door as specified while achieving high precision high-end results which the most demanding exclusive door clients find highly desired and valuable.
1. Perfectly Smooth Veneer Problem
High end veneer doors need to be perfectly smooth. Because the veneer skins are so thin, you will notice “telegraphing” on the skin surface. The term telegraphing refers to essentially the bleeding-through of any of the under-laying surface, which will impact the viewable surface area of the veneer.
If you apply veneer directly to a plywood surface, for instance, in the right light, you will be able to see the terrain of the plywood through the thin veneer.
In large doors, it can be extremely difficult to find a large enough piece of smooth underlayment material, so if there are seams in the material under the veneer, this would also telegraph through to the surface.
One way to achieve a perfectly smooth surface is to use LVL (which is commonly used by most standard door manufacturers underneath wood veneers) or MDF which are smooth but heavy, and both are limited in size availability. So, if your high-end veneer door is oversized (over 4 x 8 or 5 x 10) it can be impossible to find a single seamless product.
2. High Precision Veneer Problem
High precision is a moving target when approaching the design and production of a veneer door. The surface material may be elegantly fashioned, but if the product which the door is made out of has a tendency to move, then you could be in trouble when the door warps, causing inconvenience and potentially expensive regular maintenance and repairs in the field over time.
Due to the nature of standard door building technologies, the AIA allows for ¼” variances for a 7 ft. span of a door. Door manufacturers and door hardware manufacturers allow for these variances in mounting and hardware. If a door exceeds movement over ¼” along any 7 ft. span, the result is a warped door, which can easily be compromised or fail altogether.

Veneer Door Solutions
Thanks to Peter Sing’s True Flat Team, you can have your high-end veneer door problems solved in a way that increases your credibility as you deliver the highest results imaginable with your most particular high-end clients.
1. Perfectly Smooth Veneer Solution
Sing’s True Flat team works hand in hand with your favorite door manufacturer, millwork, or custom door manufacturer to provide a perfectly flat, smooth surface for applying your favorite veneer to.
For years, Sing’s factory located in the pristine pacific Northwest in Washington State, has been providing the biggest and best door manufacturers in the world with large smooth surfaces for applying veneers for wood doors. Sometimes Sing’s factory applies the veneers, and in other cases Sing only provides the substrate in the form of door blanks to which the door companies apply their own veneers to.
Seamless technology. Thanks to Sing’s patented veneer door core, his factory is able to provide a perfectly flat surface hosting undetectable seam(s). While seams may be unavoidable due to the large size or a particular door, Sing has the patented technology to create an unfinished door blank veneer substrate that will not move, period.
Once the substrate is prefinished and primed, seams are undetectable. While this may be of concern for other veneer door substrates, such as LVL or MDF, this is not a problem for becoming detectable later, because Sing’s veneer door substrates are built not to move, at all.
2. High Precision Veneer Solution
Sing’s patented veneer doors core substrate is built to the highest precision standards (+/- .006 in. tolerances) which means a lot to those special clients who have the highest expectations (like military, science, technology, and aerospace industries). Why not deliver this same high level of precision to your clients who deserve the best?
In fact, Sing’s veneer door blanks, whether they are pre-skinned with wood veneer or veneered by your favorite door building professional, are guaranteed not to warp, bend, twist, cup, or otherwise fail for 50 years.

Just like the tallest doors in the tallest building in the United States of America at One World Trade Center, your doors could reach new heights in veneer door manufacturing backed by the only 50-year Non-warp and Structure Guarantee.
How Can I Get a Sing Veneer Door?
Admittedly, says Sing, “We don’t build doors,” as they only provide the best materials to the door companies, millworks, and high-end custom door manufacturers to build the best doors. So, if you want a Sing veneer door, all you have to do is to contact your favorite door manufacturer and tell them you want, “Sing Core inside,” your veneer door.
Then Sing and his True Flat Team will work in concert with your people to provide you with the best veneer door in the world, guaranteed for 50 years.
Standard sandwich panels utilize an insulating foam core sandwiched in between two thin sheets of hard material. However, this design offers very little strength and durability. Sandwich panels made by Sing Core are stronger, lighter, and more eco-friendly than these conventional panels because we replace the standard foam core with our patented vertical grain, natural veneer torsion box grid also known as the Sing Core. For the consumer, this translates into a higher quality product at a fraction of the cost.
Insulated doors made with traditional sandwich panels are highly susceptible to dents and structural damage because of their weak foam core. Doors made with our Sing Core sandwich panel technology can withstand much higher impacts resulting in little or no damage due to our unique core properties. The University of Washington has confirmed that our doors can withstand pressure of up to 660 psi, as compared to the average sandwich panel which can only withstand 60-100 psi.
If you desire products that are lightweight, strong, durable, dimensionally stable, and eco-friendly, then you must try our Sing Core Sandwich Panels. We like to demonstrate our confidence in the integrity of our products by offering our customers a 10 year structural guarantee.
The simplest and least expensive way to join sing panels is to join in any way according to your budget and/or expertise.
Due to Sing Panels being so straight and true it is easier to join panels together because they line up perfectly unlike other building materials.
In many cases, for instance, standard 4×8 panels can be nailed, glued or channel-joined quickly and easily with satisfactory results.
Other options for fastening panels may include cam locks (see examples left and right) that can be pre-installed, making assembly and joining easy and more secure.
The Sing cam-lock panel solution is a high-demand solution for panels that are routinely assembled and disassembled, especially in moveable walls, trade show booths, and various wall cladding applications. See: Cam Lock Panels

Thru-bolt Joining
One of the most inexpensive and secure ways to join sing panels is by utilizing a simple nut and bolt connection method, especially, if the panels will be routinely or repeatedly assembled and disassembled.
Stainless steel nuts and bolts offer the safety and security when joining sing panels.
Biscuit Joining
In many cases, Sing Panels can be pre-configured for biscuit joining at your site of factory.
Especially for large projects, this enables Sing Core panels to be sent individually, reducing shipping and handling costs, for assembly at your facility or job site.
See images below for example of biscuit assembly of Sing Panels
Unless specified Sing Panels do not ship edge-banded as 93% of our wholesale customers do their own edge-banding when finishing their Sing Panel.
Edge banding can take many forms from vinyl and plastic to wood and steel. Sing Panels are not intended for use as an un-banded product and may not qualify for our 50 year warranty if un-banded.
If your intention is to get the best, most long-lasting performance from your Sing Panels, feel free to take advantage of our free consultation to be guaranteed to achieve the results that you desire.

Advanced Large Panels
Sing Core specializes in extremely large panels (up to 50 feet) that are extremely true flat and use our nearly seamless assembly process.
This is the most high-end and expensive process where we perform the highly specialized meticulous work in our factory yielding the high level of perfection that many of our most discerning clients require. See: our clients.
These must be manufactured in our plant to ensure accuracy with tolerances within thousandths of an inch and are more costly to ship due to the nature of their being larger than multiple panels that can be assembled on-site.
Connectors for Connecting
Cam-Locks
One of our many features is the ability to add fasteners/locks to our panels…one example of this is the “S-Hook Lock” with a turn of the hex wrench you can fasten or unfasten your panels quickly.
The “S-Hook” fastening lock that is attached to the side of these panels to allow for easy assembly of the wall system.
With a quick turn of your wrist on the hex key your panels will be attached to each other.
Barn Door Assembly or ‘H’ Channel
If you are planning to keep your panels as a permanent structure you may choose the H-Channel attachment feature. Apply your adhesive the slide panel into the channel on each side then either veneer over the panel and channel or you may choose to putty, sand and paint your panels to cover over the H-channel.
Tongue and Groove
Tongue and groove is another fastening choice especially if you using our panels for flooring or ceiling. Make a nice almost seamless connection but give wood veneer a hardwood flooring appearance.
Biscuit Joint
This is a modified biscuit joint attachment. Similar to the H-joint the you are using a single long “beam” as the connector and gluing them together. Best use is for oversize tables (such as vacuum tables) and oversize doors as well. Because our panels are made of honeycomb rather than solid wood, they will not warp. Our honeycomb is light and strong.
Ship Lap
The ever popular ship lap as a connector alternative.

Sing Punch-Proof Doors
SINGCORE-The new generation of door making it impossible to punch through and destroy.
As low as $50 a door for a door that will last a lifetime.
Today, the most common doors found in private residences contain a paper core. These doors are flimsy and are easily punctured, even when slightly impacted. Owners of these doors find themselves spending time and money on repairs, replacements, and installations that would not have been an issue had they purchased a door from Singcore. Singcore doors do not cost much more than paper-core doors, yet they have been tested to be at least 49 times stronger.
Door Security
How secure are your doors? With our patented core, you can rest assured that our torsion box technology will stand up to harsh treatment and all weather conditions. Our doors have been thoroughly tested and have been proven to withstand the impact of a sledgehammer. There is no comparison between the stability, structure, and strength of Sing Core doors versus paper-core doors.
This is a Sing Overhead Garage Door Panel compared next to a typical steel overhead garage door panel. Same size and thickness but as you can see the steel panel buckles with only a few pounds put on it while the Sing Panel holds almost all of Inventor Peter Sings weight without any problem.
Stronger than Steel,
Lighter than Wood
Doors do not have to be made out of steel to be rigid and strong. Sing Core doors are stronger and lighter, than steel and vinyl doors. Standard steel overhead garage doors are made of steel so thin that a golf ball can dent it. This is not the case with Sing Core doors. We offer higher quality doors at prices competitive with steel doors with quality superior to wooden doors.
Sing Core doors are more stable, provide better insulation, and are far lighter than solid wood doors. The torsion-box core holds the Sing Core door flat, ensuring that that the panel will not warp and sag like ordinary wood.
Patented Sing Door Methods
Sing Core doors are versatile and customizable. Every order is custom designed with the client’s project in mind. Each door is constructed using methods that specifically cater to our customers’ individual needs. We construct our doors using the following methods: pole barn grade, paint grade, wood grain grade, andplank grade.
