New Revolutionary Door Technology by Sing Core

We offer our services to support door manufacturers in building stronger, lightweight, high precision and warp-free (AWI warp standard) insulated doors using our patented and patent pending Sing Door Blanks and Sing Stile and Rail frames.

Sing Core’s specialty is assisting to create incredibly large and extremely wide door panels which door manufacturers can utilize to build the most challenging high-end doors.

Large Quantity Production Runs

We can also assist in the high-quantity production runs for doors using our facility to pre-build base doors which might otherwise create a bottleneck for common door manufacturers. We love taking over the assembly line bulk of your large door orders with rapid turnaround times.

You choose your method of building your Sing Core door blanks:

1. Sing Door Core Panel

You specify the length, the width, and thickness of your Sing door blank, built to your specifications. You determine the insulation value and skin material, and we do the rest. The Sing door core panel method is the strongest and best Eco-friendly insulated door solution for any sized door, even large oversized wooden doors, available in almost any style.

2. Stile and Rail Door Frame

For our customers and their clients who prefer the standard design of stile and rail doors, we provide the manufacture of a stile and rail formatted frame made of any combination of Sing panel, post and beam configurations to create the most sustainable stile and rail doors, which are finished by only the best millworks and custom door manufacturers. Sing Core provides the most significant improvement to stile and rail technology (besides automation) in the last 100 years to create the strongest, lightweight, most high-precision, and warp-free performance in the history of the door industry.

Doors of Almost Any Style Could be Made with Sing Core Inside

1. Pivot Doors

Pivot doors are the highest and best use of Sing Core because for the most part, pivot doors are quite large in size and are often much thicker than a standard door. If your intention is to feature a real wood finish, you know you’re going to be in trouble, that’s when the warp-free attributes of patented Sing Core shines through as the only way to build a large wood door which can be guaranteed to offer warp-free performance over time: 50 years, guaranteed, on professional grade doors.

2. Sliding Doors / Pocket Doors

Sliding Doors often present problems when they are very large due to their sensitivity and tendency to move, bend, or cup in response to changes in the environment, for which Sing Core is the perfect solution.

Large bypass sliding doors are likely to deface, scar, or otherwise damage themselves if they are not kept straight and true by being built with Sing Core inside in advance of bypass door failure.

Pocket doors, which are the most problematic of all sliding doors, because they hide within a cavity are highly benefited from being built with Sing Core inside. If warped, the finish of the door may be compromised as it brushes against the frame or cavity’s interior, and if it cups or bends too far, may become lodged either inside or outside of the pocket unable to open and close as a door. Sing Core keeps them straight and true.

3. Hinged Doors

Hinged doors are for the most part manageable even when facing a certain degree of warp, which is normal in normal sized doors. Problems arise when doors are very large, especially if over 7 ft. tall or 3.5 ft. wide. Any movement or change in the door’s being compromised is increased exponentially in relation to the dimensions of the door. Not a problem with Sing Core’s professional door blanks.

Diverse types of hinged doors, such as French doors, sliding folding doors, front entry doors, and carriage doors (among other types of hinged doors), all present varying challenges when migrating from the drawing board to the real world, and Sing Core makes the difference.

Door Sizes

While Eco-friendly insulated Sing door blanks could be used in doors of any size, the efficacy is maximized in door performance in any door over 7 ft. tall and 3.5 ft. wide. This is why you find Sing Core inside the largest doors in high-end homes, businesses, and industrial sites, because it’s the only way to build a large door which can remain straight and true, regardless of the size of the door, while still remaining lightweight.

Door Shapes

Since every door slab manufactured by Sing Core is likened unto a one-of-a-kind piece of art, architects and designers are free to create a door of any size and shape using any available flat building material.

Sing door slabs can be created to accommodate any shaped design in any thickness, and so it goes for any shaped light cutout for glass openings.

Skin Options

Sing door slabs are available in almost any skin you want, limited only by flatness (surface material must be flat), ability to be laminated, and availability.

Some examples include, paint grade plywood, aluminum, brass, cement board, cold rolled steel, concrete, diamond plate steel, fiberglass, FRP, galvanized steel, glass, hot rolled steel, LVL, Masonite, stainless steel, any wood species including exotic species, and many more.

Our most common specialty includes the cold pressing of solid wood stave to our patented and patent pending core material, resulting in natural wood doors that can be guaranteed to remain warp-free for 50 years. Unheard of in the wood working industries. We also supply high end millworks with hot-press-ready warp-free substrates to apply their skins to.

Light Openings

Available in any size and any shape, based on your drawing(s).

STC-rated Sound Doors

We assist in the creation of sound reducing or sound proof doors which can be STC-rated at our local world-renowned pro sound testing lab. Some typical composite configurations include combinations of steel, sheetrock, MDF, and other materials to achieve the sound proof results to meet your specifications.

Fire Proof Doors

We build fire proof doors to your specs and can have them rated at the fire-rating facilities selected by our fire proof door clients.

And that’s just scratching the surface…

Don’t Get Stuck with a Fake Sing Door

Does Your Door Have Sing Core Inside?

If your door has Sing Core inside it can come with a full 50-year warp-free guarantee. No other door can be guaranteed like that, unless it has Sing Core inside.

It is rare, but there have been occasions when a door has warped, when someone thought it had Sing Core inside, but it did not.

For instance, last year, an architect in Florida specified a large wooden door with Sing Core inside. The contractor contacted Sing Core and received an initial price quote.

Nine months later, we received a call from the architect who had been contacted by the building department that reported that a large wooden door with Sing Core inside had warped.

We searched our records and could not find any record of the job. We did discover the initial price quote request from the contractor who must have found a different way to make the large door.

Your large door with Sing Core inside comes with a certificate of authenticity and guarantee.

Be forewarned, if your large wooden door doesn’t have Sing Core inside, you can expect it to warp.

Make sure your large doors have Sing Core inside.

Sing Core: The Secret to Building Warp-Free, Large Pivot Door

A 50-Year Pivot Door Guarantee That Stands Out

If you’re an architect or designer working on a large pivot door, always ask about the warranty. Most companies only offer a one-year guarantee, especially excluding large pivot doors because they often warp. Why risk it? Sing Core offers a 50-year warp-free guarantee, so you don’t have to worry. Instead of stressing over warping issues, you’ll have peace of mind knowing your door will stay flawless for decades.

If your door manufacturer doesn’t offer this kind of warranty, specify that your door must have “Sing Core inside.” With Sing Core, your door is not only impressive but built to last as long as your home does.

Building a Warp-Free, Large Pivot Door

Pivot doors are stunning features in high-end homes. However, their large size and lack of side hinges present challenges. Keeping these doors warp-free is critical. Without side hinges to stabilize them, pivot doors must be designed to withstand daily use. Traditional large doors, made with wood cores or wall-like frames, tend to warp. A wall can’t handle the same impact as a door—so why build a door like a wall?

 

Sing Core Pivot Doors

Why Pivot Doors Warp and Fail Over Time

Large pivot doors are especially prone to warping. Natural materials like wood shift due to changes in temperature and humidity. This makes it difficult for conventional doors to stay perfectly straight, especially over time. If a door frame is built like a wall, it will eventually fail. Doors face more stress than static walls. Without the right reinforcement, these doors start to sag, warp, or break down from daily use.

How Sing Core Revolutionizes Pivot Door Design

Sing Core is the game-changer. This patented technology turns pivot doors into high-performance works of art. Architects and door manufacturers across the U.S. choose Sing Core not just for its 50-year warp-free guarantee but for its precision. With a tolerance of ±0.006 inches, Sing Core is one of the most accurate materials in the composite industry.

But precision isn’t its only strength. Sing Core also boasts 660+ PSI, making it stronger than steel pound-for-pound. Its lightweight strength keeps large pivot doors straight and stable, even in extreme conditions. The result? A stunning, warp-resistant door that’s easy to use and beautiful to look at.

See this short video clip of a designer of this spec home purchased for $38.5 million dollars talking about his large pivot door with Sing Core inside.

 

 

Luxury Homes Demand Perfect Pivot Doors

In a luxury home, every detail matters. When you invest millions, the front pivot door—the focal point of the property—should reflect that. A custom-designed pivot door makes a bold statement, welcoming guests and enhancing curb appeal. With Sing Core inside, your front door will not only look stunning but remain flawless for 50 years, free from warping or sagging.

High-end architects and developers are embracing the trend of designing large pivot doors for dramatic entrances. The bigger the door, the more impressive it looks. Real estate developers know these grand entryways boost a home’s value and attract buyers with their striking curb appeal.

Pivot Door Styles: More Than Just a Center Pivot

Pivot doors often have a center pivot, but it’s not the only option. While a centered pivot gives a 50% opening, moving the pivot closer to one edge creates more access on one side. For maximum clearance, you can even opt for an edge-pivot door, which works like a traditional hinge door.

A great example is the 10×12 double pivot doors at the Center for Architecture & Design in Seattle. Each door is 12 feet wide and 5 inches thick, opening to reveal 23 feet of access. These doors also include a man door for daily use, so you don’t need to open the full pivot door every time.

Creating Floor-to-Ceiling Pivot Doors

Large pivot doors aren’t limited by size. They can span from floor to ceiling and be customized to any width or thickness. In modern homes, many designers are pushing the limits with pivot sliding doors. These doors combine pivoting and sliding hardware, creating accordion-style panels that separate or combine spaces effortlessly. Pivot sliding doors are perfect for open-plan living areas, offering flexibility to transform rooms into one large, connected space.

 

 

What Makes Sing Core Pivot Doors Unique?

With Sing Core inside, you can design pivot doors using materials that would otherwise be too heavy or prone to warping. Common materials include:

  • Metal: Aluminum, stainless steel, or galvanized steel
  • Natural woods: Mahogany, walnut, cedar, or exotic species
  • Stone: Marble, granite, or sandstone
  • Concrete: Ideal for modern industrial designs

Thanks to Sing Core’s lightweight structure, these heavy materials can be used without sacrificing performance.

The Lightweight Solution for Heavy Pivot Doors

The problem with large pivot doors isn’t just warping—it’s weight. Heavy doors put strain on hardware and can even damage the surrounding structure. Over time, this can lead to costly repairs and constant maintenance to keep the hardware and frame intact.

Sing Core solves this with its strong yet lightweight core. The torsion box design keeps the door solid and rigid without extra weight. The interior grid is also filled with rigid insulation, enhancing soundproofing and boosting energy efficiency with added R-value.

The Sing Core Advantage: Guaranteed Warp-Free for 50 Years

Without the right core, natural wood pivot doors will warp, twist, or cup over time. But with Sing Core inside, you won’t have to worry. No matter the size or material, doors built with Sing Core keep their structural integrity for 50 years.

This patented technology is a game changer for large pivot doors. By partnering with top door manufacturers and millworks, Sing Core provides custom panels for high performance and long-term durability.

If your door doesn’t have “Sing Core inside,” you may find yourself dealing with warped doors sooner than you think.

 

Conclusion: Elevate Your Home with a Sing Core Pivot Door

If you’re designing a high-end home, your pivot door should be as reliable as it is beautiful. With Sing Core’s patented technology, you can have both. Architects, designers, and homeowners trust Sing Core to deliver lightweight, warp-free pivot doors that stand the test of time.

When choosing a door manufacturer, make sure to ask for Sing Core inside to guarantee that your door remains flawless for 50 years. Whether it’s a pivot front door, sliding pivot panels, or custom oversized entry doors, Sing Core offers the precision and durability that other materials simply can’t match.

Don’t cry over warped doors—Sing about 50 years of fail-free service!

Breaking News: Concealed Pivot Door Hardware

It is well known among the high end pivot door industry that Sing Core pivot door blanks are the only way to create the best lightweight, high-strength pivot door of any size (even extremely large in size) that can be guaranteed not to warp, bend, twist or otherwise fail (including full structure warranty) for 50 years.

The Only 50 Year Warp-free Guarantee and full structure warranty

Breaking News FritsJurgens Pivot Door Hardware

It’s no wonder the clients who use patented Sing pivot door core to build their high end doors are using the latest in leading edge pivot door hardware. While your pivot doors for the elite may feature any type or style of pivot door hardware made by any of the most popular pivot door hinge manufacturers, one new type of pivot door hinge is getting installed in more large pivot doors with Sing Core inside.

Breaking News

It has come to our attention that the new System M hardware from FritsJurgens in Holland is what all the latest buzz is all about.

What’s the big deal?

The big deal around Sing Core is always about big pivot doors. Not only big pivot doors but the biggest pivot doors because you could be talking about thousands of pounds of a large pivot door, which could be reduced to ten percent of the weight by having Sing Core inside.

Architects, our custom door manufacturers and millwork clients rely on the lightweight fail-safe aspects of pivot doors made with Sing Core to keep your project, not only at the elitist level of excellence, but within a reasonable budget. While those huge pivot doors can be very expensive to build and handle, the sheer weight of the door dictates the hardware necessary to accommodate such a door.

Installation of the hardware to operate an enormous pivot door can require extensive engineering efforts as well as becoming a burden on the installation, especially if it is being retrofit into an existing structure (not so bad if prepared for in a new structure being built).

Then comes along Holland’s FritsJurgens with the perfect match of sleek System M hardware that is the easiest pivot door hardware to install, especially in a retrofit application, carrying a weight of up to an 1,100 pound pivot door. That could be a 37 foot tall pivot door with Sing Core inside!

Concealed Pivot Door Hardware

The pivot closer is concealed within the door, not the floor! Making this the easiest to install pivot door hardware, requiring very little modification at the job site to install. Some of our custom pivot door builders are able to transport a completed pivot door system fully installed and pre-hung from their factory or millwork to the job site for the easiest installation of pivot doors ever, thanks to FritsJurgens’ System M nearly concealed hardware.

If you’re using a Sing pivot door blank for your pivot door substrate and you plan on using FritsJurgens’ System M pivot door hardware, all you have to do is let our design staff know when you’re placing your order. Sing Core can pre-install the required blocking necessary to accommodate the FritsJurgens System M pivot door hardware.

If you’re upgrading an existing non-Sing pivot door to a pivot door with Sing Core inside, you will be glad to know that FritsJurgens’ new System M closer works with existing FritsJurgens top plate and top pivot.

At present, this is a leading-edge well-kept secret among the most elite high end custom door manufacturers, but we thought you would like advance notice before this product becomes more widespread in use across the United States.

According to John Derosa, “The M is a wonderfully engineered, highly advanced pivot closer that is changing the technology of pivot doors. The fully adjustable M is the closer solution for large, heavy pivot doors without having to install any hardware into the floor or the ceiling.”

Here are some of what you can expect from your FritsJurgens System M Closer:

  • Everything in the door, nothing in the floor or ceiling
  • Super thin profile for min thickness doors 1 3/4″ (or thinner?)
  • 5 different models to choose from based on door width, weight, location of pivot (M32A, M32B, M32C, M32D, M32E)
  • Holds 661 lb doors and up to 1,100 lb doors under special circumstances
  • Adjustable speed, backset, floor plate and more adjustments

With the prevalence of pivot doors | pivot entry doors are being included in high profile contemporary architecture design, the most impressive pivot entry doors are oversized. These large pivot doors are generating a great deal of inquiries to one pivot door company for solutions to a variety of challenges associated with the large pivot entry doors.

The only 50 year warp-free guarantee and full structure warranty

Sing Core is providing the solution to the best pivot door companies for most of the problems associated with the large pivot entry doors.

Helping your favorite pivot door company create warp free wooden pivot doors of any size ~ guaranteed

Pivot Entry Doors | Warp and Structure

First of all, most of the most impressive architectural pivot entry door features natural wood. It doesn’t take much effort to imagine what the problems might be for a natural substance, like wood. The very nature of the grain, which add to the elegance and beauty of any pivot entry door, is the problem, especially for exterior pivot doors. While natural wood grain is so very attractive, it is natural and tends to warp, bend and twist due to changes in the environment. Even if the exterior pivot door is not made of wood, the structural integrity may fail, especially if the door is over 8 ft. tall and/or 4 ft. wide.

Pivot Entry Doors | Weight and Pivot Door Hardware

Secondly, a large pivot entry door is going to be very heavy in weight, which is expected with any door of significant height, width and thickness. Current trends to an increase of pivot entry door sizes pushes the physical limits of the capabilities of any standard pivot door company or their ability to accommodate pivot door sizes that are over 8 ft. tall. Additionally, the weight of these large pivot doors determine the type, style, and size of the accommodating pivot door hardware required. Heavy duty pivot door hardware appropriately matched can cost many times the cost of the pivot entry door, just for the pivot door hinges. Heavy large pivot entry doors also are problematic to ship to and handle at the job site, adding extra charges to installation costs.

Pivot Entry Doors | Ongoing Maintenance Costs

With the continued use of heavier large entry pivot doors over time, the regular articulation of the pivoting door causes extra stress and strain on the pivot door hardware, frame and structure as it is used. In addition to regular maintenance of the exterior pivot door’s tendency to move (warp, bend, twist or cup) other maintenance costs include repairing and/or replacement of pivot door hardware, framing and the building’s structure.

Pivot Entry Doors | Replacement Doors

Sooner or later, the owner or manager is faced with the task of locating a replacement pivot entry door. When contemplating replacing architectural pivot entry doors, management is faced with having to deal with the entire process all over again in hopes of a better resulting outcome. The replacement of architectural pivot entry doors is the result of the complexity of building a pivot entry door that is less likely to fail, or to fail less than its predecessor. This is why pivot entry doors, especially if they are over 8 ft. tall are excluded from warranty of the pivot door company at the time of installation (see your contract paperwork for the exclusion).

Only pivot entry doors with Sing Core inside can be guaranteed not to warp, bend, twist or otherwise fail for 50 years, including a full structure warranty.

No other large pivot door solution can match the power of Sing Core. Here’s the latest straight talk about pivot doors:

Pivot Doors Straight Talk

The only 50 year warp-free guarantee and full structure warranty

As the demand for large pivot doors is on the increase, the bigger they are, the more impressive they are, also, the more apt they are to fail due to door warp. Let’s face it, a door that is not straight and true is of little use as a door at all.

It is imperative for large pivot doors to remain straight and true, and the design team at Sing Core has created a full battery of patented and patent pending solutions to keep any large pivot door, made of any material perfectly straight, far exceeding AWI standards for flatness. The true flat experts at Sing Core have the knowledge and ability to create large pivot doors will not warp, eliminating the biggest complaint about pivot doors.

So, if you want a straight pivot door, the only way to get one made and guaranteed to remain warp-free for 50 years is to do what most contemporary architects, designers and engineers do, and that’s to specify that you want your doors to have, “Sing Core inside.”

Pivot Door Problems

Large pivot doors with Sing Core inside also solve other problems facing architects and designers, including, but not limited to…

Heavy Pivot Doors

Large pivot doors are big and heavy in weight. The large size and the heavy weight is problematic for a number of reasons. First of all, you must find a custom door manufacturer or millwork to take on such a project in the first place. Anything that is large is going to be difficult to create and manipulate through the building process just to create the mammoth door in the first place. Then you have to be able to move the door from the factory to the truck, using a combination of manpower and heavy equipment. Then transport the large pivot door from the factory to the job site. Once at the site, more manpower and heavy equipment is required to unload and move the door to where it will be installed. Installers now have to deal with the door, moving and fine tuning it to fit the space and attach the appropriate heavy duty pivot door hardware which can cost many times the price of the pivot door.

Heavy Duty Pivot Door Hardware

Expensive heavy duty pivot door hardware is required as the hardware is determined by the weight of the door. Even though this hardware is designed to handle a heavy weight pivot door, the straight talk is, if the door is used regularly, the hardware will start to breakdown and fail over time.

Large Pivot Door Maintenance

Which brings us to maintenance on the large pivot doors; yes, your large pivot door is impressive and leaves a great first impression but the more consistent lasting impression is left upon the pivot door’s owner who must bear the cost of constant repair and maintenance over the life of the otherwise magnificent large pivot door. As huge pivot doors are used, they cause stress and strain, not only on the hardware, but also the structure, creating the need for maintenance and repair on the pivot door for warp, the hardware as it deteriorates, and the structure for stress and strain.

Large Pivot Door Insulation

In most large pivot doors, little thought is given to the insulation value of the door. While large pivot doors are commonly thicker than their hinged cousins, the large pivot doors may not provide for energy efficient handling of thermal separation or elimination of sound penetration.

Large Pivot Door Danger

If you have a large pivot door, operating it may be problematic, especially when delicate little fingers are around when the pivot door is opened and closed. Large pivot doors are so heavy that there is the danger of injury to anyone, not just children, when the doors are in motion.

Pivot Door Solutions

Thanks you Sing Core, you can save money and have a better large pivot door experience over time, as the Sing solution is applied. Here are some of the solutions you can expect by specifying that your pivot door has, “Sing Core inside.”

Lightweight Pivot Doors

If your pivot door is built with Sing Core inside, it can weigh a fraction of the weight of any other solid core pivot door. The energy savings in just the creation and transport of your Sing pivot door help to make it more ecologically responsible, using less energy to create, ship and handle. But there’s more…

Lightweight Pivot Door Hardware

Because the type of pivot door hardware is based on the pivot door’s weight, a lighter weight door requires a pivot hinge which is matched. Real cost savings can be realized by being able to use the less expensive pivot door hardware, bring the cost of the hardware way down.

High Strength Pivot Doors

Your Sing pivot door is very strong as it was university-tested and rated at 660 PSI in strength, making it stronger than steel pound for pound. This superior strength is due to the patented insulated reinforced vertical grain torsion box core. Without Sing Core inside , you are limited to the ability of the material used to maintain the pivot door integrity over time.

Sing Pivot Door Maintenance

When your pivot doors have sing Core inside they are also nearly free of regular maintenance. If you have a professional Sing pivot door that does not warp, then you possess a large pivot door which can be guaranteed not to warp, bend, twist, cup, or otherwise fail for 50 years. Plus, if the door is damaged for any reason, it can be quickly and easily repaired on site (often without have to dismantle or remove the door) without compromising the pivot door’s strength or integrity. In addition, the lightweight of your Sing pivot door, means much less stress and strain on the hardware.

Sing Pivot Door Installation

Being so lightweight reduces costs and time by being so lightweight. Due to the bulky size several people will need to manipulate the door, but no heavy equipment will be needed because the crew can easily maneuver the large pivot door without much trouble. In fact, we commonly hear back from the installers about how they couldn’t believe how light and easy to work with large pivot doors with Sing Core inside are.

Insulated Pivot Door

Sing Core pre-packs your large pivot door with insulation wall to wall inside the torsion box structure imbuing your large pivot with increased ability for climate control and also sound deadening capabilities that are hard to find in other large pivot doors. If you’re thinking about separation between room, or particularly a pivot front door, the added insulation factor is of huge benefit and included in every Sing pivot door blank at no extra charge. Insulation upgrades are available per your specification.

Sing Pivot Door Safety and Security

Due to the increased insulation and high strength of your pivot door that has Sing Core inside, you can enjoy a greater sense of safety and security. The high strength will prevent breaching the door from unwanted guests. These are often used as impact doors. If you kick other lightweight pivot doors, they could easily fail and offer egress to an otherwise secure environment, but if you kick a Sing pivot door you will not break the door. You are more likely to break your leg and the sound deadening characteristics inhibits eavesdropping.

In the event a child, or anyone, gets their hand or fingers caught in a Sing large pivot door in motion, the likelihood of surviving such an event is much more likely as less damage will occur thanks to the Sing solution being so much lighter in weight than other large pivot doors.

Shouldn’t your pivot doors have Sing Core inside?

Exporting Eco-friendly Building Materials Made in the USA

The lightweight and high-strength attributes of SingCore are spanning the globe as designers, architects, and project managers continue to specify their projects have, “SingCore Inside.”

The only 50 year warp-free guarantee and full structure warranty

SingCore is the secret ingredient in building projects – especially those of large size and components with long spans – where certain challenges become apparent in translating the creator’s vision to real life.

Many problems associated with large, oversized projects or elements become apparent when attempting to bring an original design to life, mostly concerned with weight and strength.

Until now, very strong building materials were heavy in weight. This extra weight creates problems for the structure in terms of stress and strain over time. Lightweight building materials may be substituted for the stronger heavy ones, but compromises are made which may compromise the strength and integrity of the project.

This is the quandary facing development teams and precisely the point where SingCore provides the solution to the problems facing developers of large projects.

Fortunately, due to the extreme lightweight of SingCore building products, such as panels, posts and beams, entire containers of building materials could be sent from the factory located in Washington State in the USA to the job site in Bangkok at a fraction of the shipping cost of other materials.

Lightweight building materials easy to transport, less risk of danger or injury

The lightweight characteristics of SingCore also enables the materials to be quickly and easily lifted by crane without risk or danger of heavier materials while being able to be indisputably and safely manhandled by staff and laborers, rather than utilizing heavy equipment to maneuver the materials throughout the job site.

37 ft. Tall Pivot Doors

If you’re designing a conference center with 40 ft. ceilings and need a row of 37 ft. tall pivot doors to act as room dividers, you are going to be faced with the issues concerning strength vs. weight. In order to keep the 37 ft. tall doors from warping, your design team is faced with the challenge.

If you dared to think, “What if I could have it all?” If it were possible, you would like to have insulation for its sound deadening qualities and climate control. Then you could just hang insulated baffles, but you would compromise the function of have pivot doors and they could easily fail as they have no strength.

Problem solvers would suggest that aluminum or steel could solve the problem, but the weight of a 37 ft. tall pivot doors would be very, dangerous to install and very expensive for the 37 ft. tall pivot doors, as well as the heavy duty pivot door hardware, which would probably cost many times the price of the large metal door itself.

This is the common paradox facing the designers dealing with the weight vs. strength issue, especially in large doors.

This is where SingCore shines as it rescues the plight of engineers and contractors fervently attempting to bring the designer’s vision come to life. SingCore is the only Eco-friendly, insulated lightweight, high-strength building material that outperforms other lightweight building materials so much, that it is the only material that can be used to build a large non-warping door of any size in any application.

Insulated Strength and Rigidity

SingCore is the provider of highly advanced high precision panels, posts and beams for high-end applications and clients all over the world. These patented building materials are unique in that they are lightweight, stronger than steel, and insulated for R value and sound deadening STC levels.

Warp-free Doors

It is now not only possible, but proven, that you can build a warp-free door of any available flat building material – even as problematic a building material as natural wood grain – and have the resulting door be guaranteed not to warp, bend, twist or otherwise fail for 50 years.

No other door can compare to the insulated lightweight strength of doors with Eco-friendly premium SingCore inside.

How Lightweight?

The weight of SingCore is easily one-third the weight (50% to 87%) of solid wood.

In most cases, a large pivot door is very heavy in weight, this requires additional shipping, handling and may require additional heavy equipment to handle the large pivot door on site as well as requiring heavy duty pivot door hardware which based on weight can be many times more expensive than the large pivot door itself.

When your large wood plank pivot doors have SingCore inside, they can weigh-in at 3 lbs. per sq. ft. Your 10×10 pivot door could weigh 300 lbs.
