Modern pivot doors are making dramatic appearances in the latest contemporary architecture designs today, and the bigger they are, the more impressive they are. Among them, the modern steel door and other types of custom modern entry doors are leading the way in new methods of approaching large modern pivot doors.
There’s no doubt that modern pivot doors represent the proverbial balancing act between weight and strength and as each modern pivot door must conduct its own balancing act according to the visionary concept of the contemporary architect, designer, or door engineer.
While pivot doors are often thought of as pivoting on a precise center point, more modern pivot doors are often outfitted with pivot door hardware that is not based on the pivot door’s center. Modern contemporary large pivot door installations can be off-center, even featuring extreme edge pivot door hardware, which can be quite impressive.
The challenge which comes with the territory surrounding the concept of modern pivot doors is associated with weight, as a heavy pivoting door will cause undue wear and tear on both the hardware and the structure requiring additional maintenance over time, and strength, as attempts to reduce the weight of the door will often result in a warped door, which doesn’t do anyone any good at all.
And modern metal pivot doors, such as the modern steel door, are by far the heaviest, followed by natural wood, which everyone already knows is a huge problem when in comes to warping due to the nature of natural wood grain to move according to changes in the environment.
To complicate things even further, imagine using modern pivot doors custom modern entry doors, where there’s a good chance that one side of the modern architecture pivot door faces the elements, possibly 100% exposed to the weather. This is a certain recipe for disaster. That is, unless your modern pivot doors have
Sing Core inside.
What is Sing Core?
Sing Core is the invention which is changing the way doors are made around the world.
Now, big pivot doors don’t have to be heavy or prone to warp, thanks to inventor, Peter Sing’s patented and patent-pending anti-warp technologies. Using Sing’s Core, you can have an Eco-friendly lightweight modern pivot door that weighs far less than any other solid wood-based core system, yet is very strong.
Stronger than Steel
How strong is Sing’s modern pivot door core? Stronger than steel pound-for-pound, and it was independently tested and rated at 660 PSI.
In fascinating strength demonstration, you will find the inventor, Mr. Sing performing amazing feats, such as standing on a 20 ft. span supported between a pair of sawhorses and see for yourself; little or no deflection. It is quite astonishing.
And with the most bold and modern pivot doors being so lightweight and strong, this is only the beginning.
Modern pivot doors with Sing’s core inside (yes, even the modern steel doors) not only weight less and are many times stronger, but they also take on an impressive set of attributes just by virtue of having Sing’s patented invention inside.
Fully Insulated Modern Pivot Doors
Sing’s doors are also fully insulated for climate control and sound deadening qualities that are hard to be found (or impossible to find) in such a door this lightweight and strong.
And if you didn’t already know, thanks to Sing’s patented and patent-pending anti-warp technologies doors may now be had made of nearly any material and any size, and come backed by Sing’s unparalleled
50-year Warp-free Guarantee
No, that is not a misprint. You might expect 5-years, but Sing guarantees that doors made to specs with his technology inside can be guaranteed not to warp, bend, twist, or otherwise fail (including full structure) for 50 years. No one else can do that.
While Sing is responsible for making the largest door impact in so many high-end industries across the board, Sing claims that he has yet to make even one door.
According to inventor, Peter Sing, he only makes the door core, or superior substrate, which he supplies to the world’s top architects, door manufactures, millworks, and custom builders of modern pivot doors, who make his inventions look so good.
Lightweight doors are the mainstay of Sing Core’s offerings, providing the highest precision lightweight door blanks to the biggest and best door companies, millworks, and custom door manufacturers in the world. But don’t let the light weight fool you as Sing Core is stronger than steel pound for pound, and doors with Sing Core inside come with a 50-year warp-free guarantee.
If you don’t already know, there’s a new way to build the best lightweight doors with the highest performance ratings in the industry using inventor Peter Sing’s patented and patent-pending technologies architects, door engineers, and door builders are able to create lightweight doors of enormous size which can be guaranteed to provide faithful fail-free service for 50 years.
How to Build a Lightweight Door
Since the late 1800’s experienced woodworkers have known the secret of building a wide, large flat wood surface was to use an interior torsion box which helped to resist the nature of wood grain to move according to changes in the environment. Torsion box was often incorporated into the designs of large spanning tabletops and very large doors. Even though the overall results were far better to build with torsion box than without it, these massive surfaces would move due to the natural wood surfaces.
A torsion box is a grid made of wood-framed boxes forming a flat grid inside of the large spanning exterior skins. This interior wood grid structure is time consuming to build, but effective in reducing the overall weight of the structure and resisting movement while increasing compression strength.
Technology presented less expensive honeycomb core alternatives to the original torsion box concept to as the answer to how to build a lightweight door quickly and inexpensively. Still, the standard honeycomb core boasts only a 10 to 110 PSI and has virtually little or no sheer strength.
Sing’s invention greatly improves on the tried and true benefits and design of torsion box substrates for building a lightweight door first by flipping the grain of the torsion box frame to perpendicular to the exterior skins. This minor tweak increased the strength of the torsion box (which used only horizontal oriented grain in the past) many times, but he wasn’t done, yet.
Then, Sing filled the voids of the torsion boxes wall to wall with rigid recycled foam insulation, creating a composite hybrid core that when sandwiched between two stress skins created a structurally sound solid hybrid composite panel which could span large areas unsupported.
This is the most effective way known how to build a lightweight door to date.
Sing’s invention has empowered architects and engineers to push the reaches of standard building materials by replacing traditional lumber or plywood with his Sing Panels. Nearly anything can be made with this new patented building material which has been independently tested to sport a minimum of 660 PSI and having the highest tolerances of any other building material (+/- .006 in.).
Sing’s factory provides the strongest lightweight door blanks for building the largest and strongest lightweight doors on or off the planet. That’s why you could find them anywhere from beneath the sea (U.S. Navy) to outer space (NASA) and everywhere in between.
Any Type of Lightweight Door
Sing’s True Flat Team can create door blanks for any type of door ever made, only the result will be lighter in weight and many times stronger than the door which preceded it. That’s why lightweight doors with Sing Core inside are growing in popularity as replacement doors in major projects and those requiring high performance and low maintenance for everything from historical renovations to leading edge scientific applications.
Imagine making any kind of door lightweight and extremely strong like,
The options available for the addition of a virtually unlimited vast variety of available doors skins from exotic natural wood grains to high-tech impervious synthetic surfaces, and you can now have any available type of metal door known to man, only have it as a lightweight metal door which is stronger than steel.
Insulated Lightweight Door
Another benefit of having Sing’s core inside your door, is that each door is fully insulated for sound deadening and climate quality characteristics, which you will not find in any other Eco-friendly lightweight door which sports such high strength and tolerances.
50-year Guaranteed Lightweight Door
These are the only doors in the world that come with a full 50-year guarantee. Your lightweight door with Sing Core inside is guaranteed not to warp, bend, twist, or otherwise fail for 50 years, including full structure and free from delamination.
If you agree with the biggest and best door manufacturers, you will be saying,
“There’s just no other way to do it,”
And you’d be right.
If you’d like to know more about Sing’s lightweight door panels, contact Sing Core.
Interior barn doors are the fastest and easiest way to fill an opening. Depending on the wall and it’s opening, a creative interior barn door solution might be something that you might like to look into before you decide on your final indoor barn door specs.
And when it comes to indoor barn doors, size makes a big difference. If your sliding barn door is over wider than a 48 inch barn door or taller than an 8ft barn door, you should consider seeking out a millwork or custom barn door manufacturer who specializes in big barn doors.
The reason you need to seek out a professional large sliding barn door builder is because it takes extraordinary skills and abilities to create a tall or extra wide barn door will not fail long after installation due to warping.
Sliding barn doors need to remain fairly straight and true to operate efficiently. The industry (according to national AWI standards) allows for up to ¼ inch deflection over a 7 ft. span to be considered straight. Hardware manufacturers and installers are conscious of movement of indoor barn doors and they allow for the quarter-inch movement.
If your large modern barn doors are over standard sized interior sliding barn doors, you will have problems with warping barn doors which will move in excess of AWI standards when there are environmental or climate changes. The bigger the indoor barn doors, the bigger the problems are due to being so large. It is exponentially more problematic for oversized wood sliding barn doors.
So, if you are particular about your interior sliding barn door, whether it is among the categories of rustic barn doors, classic barn doors, or modern barn doors, you want indoor barn doors that are not going to warp or cause you headaches due to requiring constant maintenance or replacement of your barn door.
Or, the next time you go to specify or purchase a barn door, you might look for a door that is the perfect match for this request,
“I want warp-free indoor barn doors that are guaranteed for 50 years.”
Asking that question will get you what you want because there’s only one way to build an Eco-friendly lightweight and high strength tall or wide barn door that can remain warp-free for 50 years, and that’s with,
“Sing Core inside.”
Now, you could try to build yourself some diy barn doors because for the most part, your local door company is not going to even offer to attempt building a barn door which is very big, because they know if they do it, they’re going to look bad when it fails. If the end user insists, they make have the barn door custom made for you, but it will likely to be excluded by means of a waiver from any warranty that might cover the rest of the job.
But, if you’re working with the biggest and best door companies in the world, when you ask for
Warp-free indoor barn doors
They give you warp free interior barn doors that can be guaranteed to remain straight and true for 50 years.
How do you build a warp-free rolling barn door?
After your sliding barn door company gets your specs, they contact inventor Peter Sing, the creator of patented Sing Core as well as other patents and warp-free solutions which are patent pending. His factory, located in the lush Pacific Northwest’s Washington State, creates the lightweight high strength warp-free barn door substrate which is revolutionizing the way indoor barn doors are made.
To answer the question, “How do you build warp-free sliding barn doors,” you must start by having the basic details about the measurements of your sliding barn doors. You will need to know the height, width, and thickness of the indoor barn doors you want.
Will your order consist of one big modern barn door, or will there be many sliding barn doors in many different sizes?
It’s also a good idea, early on, to know what type of material you would like your interior barn doors to be made of.
You can specify nearly any flat building material to be used for your custom sliding barn door. Some types of indoor barn door include:
Aluminum Barn Doors
Brass/Bronze Barn Doors
Ceramic Barn Doors
Cold Rolled Steel Barn Doors
Copper Barn Doors
Diamond Plate Steel Barn Doors
Fiberglass Barn Doors
Formica Barn Doors
FRP Barn Doors
Galvanized Steel Barn Doors
Hot Rolled Steel Barn Doors
HPL Barn Doors
Laminated Barn Doors
Masonite Barn Doors
Stainless Steel Barn Doors
Wood Species Barn Doors
Just to name a few.
Plus, Sing’s patented and patent pending indoor barn doors offers many other characteristics that are the envy of any other method of manufacturing any kind of door in the world. Some of the features you will be happy to have, thanks to Sing’s core include (but are not limited to):
1. Eco-friendly
Made naturally in the Pacific Northwest with low energy consumption and conscious use of raw materials such as natural wood grain stock, recycled goods, formaldehyde-free adhesives, and the light weight of Sing’s core consumes less energy in the shipping process, reducing the carbon footprint of every door with Sing Core inside.
2. Lightweight
Sing’s sliding barn door solutions weight one-third or less the weight of other wood based indoor barn door core material. The lightweight of sliding barn doors with Sing’s core inside means, less expensive hardware (which is based on the weight of the door), less stress and strain on hardware and structure over time, easier to handle, ship, and install.
3. High Strength
No Eco-friendly lightweight structure material is stronger than Sing Core. Other honeycomb cores are weak (only 10 to 110 PSI), while Sing’s core has been independently tested at 660+ PSI, that’s stronger than steel pound for pound. Mr. Sing’s strength demonstrations are well known as he stands on unsupported large spanning one-inch panels with little or no deflection.
4. High Precision
Patented solid composite hybrid Sing Core is very high precision with high tolerances (+/- .006) with the most impressive shear strength, and can be precision-sanded within thousands of an inch.
5. Fully Insulated
Sing’s core is fully insulated for both sound deadening and climate control. Standard R-rating is R3.5 to R6.5 per inch and can be re-engineered to meet higher specifications and STC ratings.
6. Any Size Barn Door
Sing’s core enables him to help create warp-free large sliding barn doors or immense size up to 50 ft. or more that can be guaranteed for 50 years.
7. Any Style Barn Door
Using Sing’s core as the base material of your indoor barn door you (or more correctly, your custom door manufacturer, millwork, or door company) can create any style of barn door from complex architectural surfaces to stile and rail designs of all kinds, supporting any available flat surface material.
Wood Sliding Barn Doors
Large wood sliding door are making a comeback. While wooden barn doors have the striking look and visual appeal, just trying to keep them straight was a real problem. Before the invention of Sing’s core, the answer was to use faux wood doors. Doors that were stamped and made of synthetic materials but made to look like wood. Now, you can have your real wood doors back again, thanks to Sing Core.
Top 10 Wood Sliding Barn Doors
Here of some of the more popular natural wood indoor barn doors that people order from Sing Core:
1. pine barn door
2. knotty alder barn door
3. oak barn door
4. walnut barn door
5. knotty pine barn door
6. alder barn door
7. white oak barn door
8. cypress barn door
9. black walnut barn door
10. cedar sliding barn door
Stile and Rail Barn Doors
Peter Sing and his True Flat Team have many specialized methods of creating indoor barn doors to meet the specs of architects and designers who want the best most sustainable doors on the planet. And when it comes to Sing’s infamous stile and rail doors, you might be surprised to find that they aren’t made of stiles and rails at all.
According to Sing,
“Stile and rail doors are weak. If someone kicks your door, it will break. If you kick my door, it will break your leg!”
Though Sing’s stile and rail and multi-panel doors look like they’re made of many pieces, it’s really just a Sing Core slab door with decorative wood or molding added to make it look like a panel barn door, or stile and rail door. It’s really Sing’s impact resistant barn door panel treatment.
SingCore’s patented core material is one of the most environmentally friendly materials on the market, combining state of the art strength and flatness with Earthly friendly materials and manufacturing practices.
Build from Sustainably Harvested Renewable and Recycled Materials
The primary components of SingCore’s system are a wooden vertical grain torsion box infilled with recyclable foam cells. SingCore uses all locally sourced wooden components in the core material. Wood from sustainably managed forests is an eco-friendly resource, with no VOAs, formaldehyde, or other potentially toxic chemical components added.
SingCore uses recyclable EPS foam that includes post-consumer or post-industrial content. The foam components are free of HCFCs, dyes, and formaldehyde and include the following environmental credentials:
LEED certification credit
Compliant with the NAHB/ANS National Green Building Standard
Energy Star approved

Eco-friendly large barn doors are taking on a whole new look and are a more sustainable solution for indoor and outdoor applications while commanding a unique stylistic approach to contemporary architectural design. The best extra large barn doors are emerging as featured presentations in all types of structures from residential and commercial to hospitality and industrial venues.
This new approach to the modern barn door is creating a stir as simple design of the traditional wood sliding barn door is now able to incorporate exciting characteristics that far surpass the simplicity of your grandfather’s farmhouse sliding door by incorporating this new generation of large architectural barn doors.
So, what makes this superior modern barn door so different from the sliding farm door of yesteryear?
While they may look similar, the large barn door hardware is much more sophisticated, but the biggest secret of all is what is found deep inside the best large barn doors of all time. If you were to look inside, you would find a patented substrate specifically designed to build the ultimate large barn doors.
Inventor Peter Sing is responsible for discovering and manufacturing this unique hybrid composite door core found inside the best modern barn doors today. Sing’s core imbues each barn door with astounding characteristics which cannot all be found in any other type of barn door, anywhere on Earth.
For instance, if your modern barn door has Sing Core inside, you will possess a door which is
Eco-friendly
Lightweight
High strength
Solid as a rock
Fully insulated
Warp-free
Guaranteed 50 Years
Large Barn Door Problems
If you were going to make a high-end large barn door for a demanding client or visionary contemporary architect, you would have to hire a door engineer with the ability to design sliding barn doors which could be built to architectural specifications. The goal is to have an end product, a large barn door, which will not warp, fail, or require regular ongoing maintenance to keep it operational over time.
If the large barn door was quite oversized, say anything over three-and-a-half ft. wide and 7 ft. tall, you would find some extreme goings on inside such a door. There would likely be some type of welded steel interior framing and other heavy inserted in an effort to keep such a big barn door from warping, a pretty toxic approach to trying to solve the problems associated with large barn doors.
This is the biggest complaint with failing large barn doors: They warp. And warping barn door, if they are warped enough, will cease to operate, and if they are very heavy, this causes extra stress and strain on both hardware and the structure itself.
Large Barn Door Solutions
Thanks to Sing and his patented inventions and patent-pending solutions there is a way to make a lightweight high strength modern pivot door which can be guaranteed not to warp or fail for 50 years. There is no other way to accomplish such a feat without Sing Core inside.
Eco-friendly Large Barn Doors
Sing’s manufacturing facility is nestled in the pristine Pacific Northwest, where ecological approaches to building and creating almost anything is of profound importance to its inhabitants. So, Sing’s factory uses the best of both worlds, basic traditional woodworking craftsmanship and advanced cold-press technologies which use very little energy consumption. Sing also uses formaldehyde-free adhesive and responsible use of natural and recycled materials, plus being so lightweight makes them easier to ship around the world using less fuel than other barn door manufacturing methods, assuring Sing’s products have an extremely minimal carbon footprint.

Lightweight Large Barn Doors
Sing’s patented and patent pending technologies empower his True Flat Team to create these amazing hybrid solid composite cores which weigh a fraction of other solid wood-based structure cores. Lighter weight barn doors mean lighter weight hardware and less stress and strain on the structure. This prevents the need for constant ongoing maintenance to the barn door, a huge savings over time.
High Strength Large Barn Doors
You might not need bulletproof barn doors, but you will enjoy having lightweight large barn doors that are stronger than steel pound for pound. Sing’s large barn door core material is independently rated at 660+ PSI and is featured inside some of the highest security doors and impact doors in the world.
You can see that Sing’s panels are so strong that the inventor can stand in the middle of this one-inch-thick 13 ft. panel with little or not deflection. That is an effective strength demonstration.
Solid as a Rock Large Barn Doors
Sing’s patented and patent pending door core technology is based on his solid hybrid composite invention which is basically a vertical grain torsion box panel where the grid which would normally be left empty is filled wall to wall with recycled rigid foam insulation. Once assembled and cured they can take a beating, and unlike other doors can easily be repaired to full structure strength if breached, which is more sustainable than replacing the whole door.
Sing says, “Kick any standard stile and rail and it will break. Kick my door an you will break your leg!”
Fully Insulated Large Barn Doors
Inherit in Sing’s large barn door core invention is full insulation throughout which offers huge advantages to not only end users, but the sound proof door and refrigeration door manufacturers who rely on Sing to provide them with the insulated substrate to make the best rated lightweight large barn doors fully formatted for sound deadening and climate control.
Warp-free Large Barn Doors
And Mr. Sing is the King of the Warp-free large barn door. All hanging barn doors move according to changes in the environmental elements which surround them, and to make matters even worse, this is more problematic when in use as an exterior door, where one side is facing a structure’s interior, while the other could be exposed one hundred present to the weather.
Sing proudly guarantees his large barn door cores not to warp, bend, twist, or cup for a very long time, in fact, 50 times more than any other door manufacturer.
Large Barn Doors Guaranteed 50 Years
Unprecedented in the industry Peter Sing fully guarantees his large barn door core not to warp, bend, twist, or otherwise fail for 50 years, including structure & lamination. Nobody has ever dared to go there, and Sing who supplies the biggest and best door companies in the world with warp-free door core for all their oversized doors says, “If I couldn’t do it, you would have heard about it by now.”
And they all say the same thing,
“It’s the only way to do it.”
For if there were any other way to make a lightweight warp-free door, you know these companies would do it themselves, but they rely on Peter Sing’s patented innovations to provide what would otherwise be impossible, so they can better serve their clientele.
In the new decade, large over-size sliding doors are landing large amount architects and design professionals all over the United States. Whether a man door type for convertible office spaces or a movable wall design for that open concept in to private meeting space ascetic, large sliding doors are set to be the hallmark of the coming decade of design. Architects, millworks, interior designers, and high end contractors all best be aware of this coming trend.

New Trends in Large Sliding Door Design
In this decade of 2020, new trends are emerging in architectural design of large sliding doors.
Man Door Sliding Door Trends
Increasingly, the use of man doors, smaller 3’0 x 7’0 or similar doors built within a massive sliding door are becoming increasingly prevalent in large interior sliding doors. Man doors allows for one opening to be used for three different uses:
Entrance and exit of personnel while in a privacy configuration
Reconfiguration of the space for an open concept or large space for special use cases / events
Movement of larger equipment or groups of people between spaces
Moveable Wall
The use of movable walls is also finding increasing use in office space design where the tenants desire the capability of an open combined use space that can be reconfigured in to smaller meeting spaces when the need arrises.
SingCore is particularly adept in large movable wall uses because our material is extremely light for it’s size, making it easy to install, easy to operate, and cheaper to install based on hardware costs. Our patented core material also boosts insulating foam material which provide excellent noise suppression and well as thermal properties.
Curved Door
In the effort to move beyond the ordinary, oversized curved doors are starting to find place in the bespoke construction industry. Curved doors offer a distinctive look that can better utilize space in many situations.
SingCore offers curved doors built to your specifications. They can be built to any size and any profile, without compromising strength or rigidity. While we can’t promise that your curved door will be “true flat,” we can promise that they will have just the right curvature for you needs, and stay that way for the duration.

Peter Sing Standing on a Sing Core Door
How You Know Sing Core is the Best
Sing Core is made of 90% foam and 10% natural vertical grain wood fiber. This honeycomb structural design creates an incredibly strong, lightweight door. It’s dimensionally stable, offers insulation, and deadens sound.
Other lightweight doors may collapse or delaminate with a hard kick. They don’t offer the same 50-year guarantee because they lack the strength and structure of Sing Core. Traditional wood-core doors swell with moisture, and the more wood used, the less stable the door becomes. Sing Core’s foam core eliminates that problem while still providing exceptional strength.
Contractors Comparing to Other Door Cores
Even ChatGPT agrees: Sing Core’s honeycomb urethane core outshines other cores. Aluminum cores, while strong, are often paper-thin and lack density. They can stretch or fail to bond properly, making them unsuitable for large, custom doors. Plus, aluminum doesn’t insulate or deaden sound as Sing Core does.
Other options like paper, cardboard, particleboard, and wood-based cores don’t compare either. These materials warp over time, soak up moisture, and often come with only a one to five-year warranty. But Sing Core’s technology guarantees a 50-year warp-free performance. For high-precision doors, it’s all about the core.

“If millworks are looking for a door with the best guarantee against warping, Sing Core stands out as a top option. They offer a remarkable 50-year non-warp guarantee on their doors. This is one of the best in the industry. This applies to a range of door types, including large, oversized pivot doors, sliding doors, and veneer doors.
Their patented Sing Core technology is used by high-end door manufacturers to create lightweight, high-strength doors that resist warping, bending, and twisting, even in challenging conditions. This guarantee is particularly important for large doors, which are more prone to warping due to their size.”
Most other door manufacturers typically offer a 1-year warranty, and in some cases, large doors may not have any warranty at all, since warping is a common issue in the industry. Therefore, Sing Core’s 50-year guarantee sets a very high standard for durability and performance.” Beauty is not skin deep. It’s what’s inside the door that counts.

How to get Sing Core. The process typically looks something, like this:
1. First, the Architect specifies, “SingCore” inside the product.
2. Second, the General Contractor seeks out a qualified Millwork who obtains unfinished pivot door from Sing Core.
3. Next, Sing Core manufactures the pivot door blank to architectural specs and ships to millwork.
4. Millwork finishes and installs hardware and provides finished pivot door to the job site.
5. Finally, installers hang and install the pivot door.

How You Know Sing Core’s the Best Door Panel Manufacturer
Sing Core is unique because it’s 90% foam and 10% natural renewable vertical grain wood fiber. In combination with its honeycomb structural design, Sing Core creates the strongest, lightweight, dimensionally stable door. These doors have the highest structural strength, insulation, and sound-deadening properties.
If you kick a door with only foam, the door might collapse or delaminate the skin. The whole structure could fail. That’s why other lightweight doors don’t offer a 50-year guarantee. This Sing Core difference is critical because moisture changes make the wood susceptible to swelling.
When you have a large door, it’s incredibly sensitive to expansion. That’s why traditional wood-core doors typically come with only a one-year guarantee. The more wood, the less stable. Sing Core being mostly foam eliminates that problem and still provides exceptional strength while remaining lightweight.
Why Sing Core is the best: It’s a honeycomb urethane core. Sing Core rises ahead of the competition compared to other cores. Aluminum core for instance is strong. However, many aluminum cores are paper-thin and lack the density needed for true structural support. Without the thickness of Sing Core, the core has a tendency not to bond well thanks to stretching and a lower thickness.
If you increase the density, you create a structure that’s too heavy for large custom doors. Aluminum also doesn’t provide high levels of insulation and doesn’t deaden sound. Sing Core, however, offers the perfect balance of strength and lightweight composition with a dimensionally stable structure that also meets insulation and sound-deaning needs.
Other lightweight cores, like paper, cardboard, particleboard, LVL, or regular wood-based cores, can’t compete against Sing Core. They tend to warp over time, soaking up moisture and often leave your clients disappointed. Most of these doors only come with a one to five-year warranty. But with Sing Core’s technology, you get a core that doesn’t warp and comes with a 50-year warp-free guarantee. For a high-precision door, it’s what’s within the core that matters.

100-YEAR FURNITURE
SingCore has been used by the Seattle AIA for their flat back style office furniture. Overall, weighing a third of the weight of all wood panels. Therefore, SingCore is extremely popular in the modular or moveable furniture space.
A variety of travel industries are benefited by using Sing’s technologies. In summary, Sing Core is used in hospitality, aircraft, aerospace, marine, rail, trucks, trailers, and RVs.
How Sing Core supports contemporary architecture and brings original architectural doors to life.
Why Specify Sing Core?
The primary reason top architectural firms specify Sing Core in their specs is for large doors because every door over three-and-a-half ft. wide or seven ft. tall is going to have a problem with warping, and Sing Core is the only way to build an Eco-friendly lightweight high strength fully insulated door which can be
Guaranteed Warp-free for 50 Years
This sets the bar extremely high, and when architects want to deliver the best for their particular high-end clientele, as specifying “Sing Core inside” elevates the project to an entirely new level.
Renowned for non-warping large doors, inventor Peter Sing’s patented and patent-pending building materials can do so much more. Next up on the list of reasons why architects seek Sing’s materials out for their upcoming projects includes lightweight dimensional stability and unsupported spans.
Here, Sing stands amidst a 13 ft. one-inch thick panel between two sawhorses, and you know if he were standing on any other building material, he would be standing on the ground. Yet, there he is suspended with little or no deflection. It boggles the mind, the possibilities of Sing’s core.
And Sing’s factory, located in the pristine forest region of the Pacific Northwest builds more than panels. He also builds posts and beams for use in other types of construction applications, which are just as lightweight and strong, if not stronger.
How Strong is Sing’s Core?
Independently tested, Sing’s core is 660 PSI, many times stronger when compared to any other lightweight honeycomb-type building material which usually clocks in at between 10 and 110 PSI.
That’s why you will find Sing Core inside impact doors. Sing says, “If you kick other doors, they will crash,
“Kick my door and you will break your leg.”
While lightweight and fully insulated, Sing Core is stronger that steel pound for pound.
Architectural Lamination
When it comes to architectural designs using high precision lamination, Sing’s factory and his high precision laminating specialists provide top of the line results with unparalleled visual impact.
Laminates can be mixed and matched in any specified pattern, orientation, or specific shapes. In fact, Sing’s stile and rail surface lamination makes his high-end door blanks look like a high precision stile and rail door, for which he is well known for in the industry.
Sing’s lamination is also included in his no-fail 50-year guarantee.
Any Surface Material
Due to Sing’s True Flat Team’s ability to keep any surface material straight and true, you will find them constantly hard at work designing the warp-free components to keep solid wood stave straight and true for 50 years, though their expertise is not limited to unstable wood grains.
Nearly any available flat building material can be incorporated with Sing’s core, including exotic natural wood grains, aluminum, brass, brick, bronze, cement, cold rolled steel, concrete, diamond plate steel, fiberglass, Formica, FRP, galvanized steel, hot rolled steel, HPL, Kevlar, Masonite, or stainless steel, just to name a few. That should get your creative juices flowing.
But there’s more
Any Size

You could find Sing Core from beneath the depths of the sea (US Navy) to outer space (NASA) and everywhere in between.
Any Application
There’s no doubt you will find Sing Core inside the finest oversized large doors, but you may find Sing’s core inside any item that is lighter in weight but expected to be used over and over again over a long life span.
100-YEAR FURNITURE
You will find Sing Core inside 100-year furniture (that’s furniture that is designed and built to last for a hundred years). This is in stark contrast to more popular inexpensive import furniture which is expected to be basically disposable.
