Large Pivot Doors

21 ft. tall large pivot door

There’s no doubt about the growth in the pivot door market. Just a few years ago pivot doors were the exception to the rule, today more and more people want to make an impact statement by featuring a pivot front door, and nothing packs more curb appeal than large pivot doors, leaving an everlasting impression. In fact, the bigger the pivot door, the better.

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

You know what having a large pivot door means? You got it = large prices, on everything. Everything is more expensive when you’re dealing with a large pivot door. Think about it… Large pivot doors are large and thick, that means they’re cumbersome and they’re hard to manage on the job site, sometimes requiring extra heavy equipment just to move them about the site. Of course, they are heavy, which means transportation is going to be expensive, as well as the heavy duty pivot door hinges (also expensive) because the weight of the large pivot door determines which hardware is needed to support the extra weight.

The extra weight can be a problem if it is being used regularly, causing extra strain on both the hardware and the structure itself; resulting in costly maintenance and repairs to the pivot door and the structure as well over time.

But wait, there’s more: Since everyone wants to have a large pivot front door that means one side of the door faces the structure’s interior while the other side is exposed to the elements, and you know what that means? You got that right: Warped doors! When is a door not a door? When it’s so warped you can’t secure it. There you go = more costly repairs.

What If…

What if one type of large pivot door could overcome all the hassles associated with other large pivot doors. I mean, if the laws of physics could be suspended for a moment, and you could have a large pivot door any way that you wanted it, what would that large pivot door look like?

Pivot Door Size

To start, size would not be an issue. You could have any size large pivot door in any thickness you wanted, without having to make a zillion calls to find anyone who would undertake such a challenge.

Pivot Door Options

You would want to be able to specify any material to have the large pivot door manufactured out of, and it wouldn’t matter if it was concrete, natural and/or exotic wood, including any metal from aluminum to hot rolled steel, or any other available flat building material. You could have whatever you wanted.

Lightweight Pivot Doors

If you could have it any way you wanted it, you would have this large pivot door weigh a fraction of any other pivot door, so that you could reduce transportation, installation and hardware costs at the get-go, as well as having less expense over time, because the lighter weight means less stress and strain on hardware and structure, and less maintenance costs.

High Strength Pivot Doors

If the large pivot door is going to be lightweight, we do not want it to be wimpy. I want to know my family is safe a secure from forced entry, and if someone tries to kick in the pivot door, I want them to break their leg. And if I accidentally drive a pair of forklift forks through it, I want to know that it’s strong enough to take the impact without compromising the pivot door, and can easily be repaired (without having to remove the large pivot door).

Warp-free Pivot Doors

Might as well throw in the idea of having a large pivot door with superior warp resistance; how warp resistant would you want? Okay, let’s say it. We want a door that does not warp, period, even if it is used as an exterior-facing pivot front door.

Pivot Door Insulation

Just for fun, we might like to throw in the idea of having a large pivot door that is well insulated to provide more safety and security from sound deadening and energy savings to superior climate control.

Customizable Pivot Doors

I’d want to be able to customize the large pivot door any way I wanted to, including custom lite cutouts in any shape and style I wanted (not being limited to having to pick from a few options). I want it the way I want it. Can we do that?

You Can Have It All

You can have all this and more! What? Surely you jest. Nope, I am being totally honest with you. You can have everything you could imagine, like unlimited size restrictions for your large pivot doors, made out of any flat building material available, weighing in at a fraction the weight of other solid core pivot doors, yet stronger than steel pound for pound and guaranteed not to warp, bend, twist of fail structurally for a full 50 years.

Oh, and you can have all the insulation you want for sound dampening and saving energy, as well as custom lite cutouts, where you want, in any shape you like.

Now, that is the perfect large pivot door

The most exciting thing about all this, is that it is not just a fantasy, but Sing Core does actually help the best millworks and door companies to supply their customers with the very best large pivot doors available in the world today.

Large pivot doors made in the USA 50 year warp-free guarantee

How is it possible?

The large pivot door technology was birthed from the imagination of inventor, Peter Sing, whose next generation reinforced torsion box design enabled him to be able to accomplish all these feats, outperforming other aerospace-inspired lightweight core materials (rated at 10 to 110 PSI), while Sing’s core clocks in at 660+ PSI. And if you want a high precision pivot door (which is why you see Sing’s products featured from beneath the sea [US Navy] to outer space [NASA]), very few materials can be made so high precision (+/- .006 in.).

With all these features and benefits, who wouldn’t want a large pivot door with Sing Core inside?

How Can I Get A Sing Large Pivot Door?

Here’s the tricky part, and I will lend you a hand, hopefully making it easy for you to get a Sing large pivot door. It’s tricky because Sing Core does not make the doors themselves, they only supply the millworks and custom pivot door manufacturers with the raw materials they need to create these large pivot doors that are anything short of amazing. And that’s the secret.

All you have to do is to go to your favorite local millwork or custom pivot door manufacturer and tell them what kind of pivot door you want, and be sure to say, “I want Sing Core inside.” It’s as easy as that. While Sing Core does not build or finish doors, they do supply the best door makers with the best material available to create the best pivot doors ever manufactured in the United States of America. And, yes, Sing Core is proudly made in the USA.

Sliding Room Dividers

Want to have complete control over a large space, in your home, conference center, hotel, museum or art gallery? One of the best ways to accomplish controlling your large space is by using sliding room dividers to divide and conquer your space. What’s more, if your sliding room dividers are insulated for sound deadening between spaces all the better. Sing Core makes the best sliding room dividers that are Eco-friendly, lightweight (10% the weight of wood), high strength (660 PSI, stronger than steel pound for pound) and fully insulated for sound dampening and climate control between spaces.

 

When architects are designing a space with the inclusion of sliding room dividers, they want to be certain to imbue the sliding wall with the characteristics necessary to deliver the results the client wants. While the style, format and layout of sliding partition walls vary across the board, the key characteristics of a sliding room divider are functionality and performance. If the job is a very high end job, the client also seeks to find high precision and maintenance-free longevity, as well as insulated sliding wall divider.

You have the flexibility and control to create a massive sliding wall or a consecutive series of sliding room divider doors, sliding barn doors, large sliding doors, even a full line of folding sliding doors, for easy opening and closing, either as a single man door for access between the adjoining areas, of slide all the sliding partition doors aside to completely open the area altogether. You will find Sing sliding wall partitions used not only as sliding room dividers, but also as art gallery walls and museum exhibit walls, like in the Museum of Science and Industry design.

Imagine being able to ship your sliding room dividers to any location at a fraction of the cost. How? Since Sing Core sliding wall components weight a fraction of the weight of other sliding doors room dividers, you can ship wooden room dividers at a fraction of the cost by reducing the weight by 90%. The lighter weight sliding room dividers makes them easier to work with on site and allows you to use lighter weight hardware, which reduces the cost immensely (sometime due to the weight of sliding door room divider the hardware can cost many times the cost of the sliding partition doors themselves).

You want your sliding room dividers to operate with ease without being a threat of potential injury. Other types of sliding room dividers can have painful consequences. Not only are they lightweight, but your Sing sliding room divider is no slouch when it comes to being every strong. The inventor says you can kick through any other sliding door dividers, but if you kick a Sing sliding wall divider you will break your leg.

Folding sliding doors , also referred to as accordion style room dividers, add an entirely new charm to the idea of sliding room dividers in that they are easy to operate and stack conveniently to either or both sides of the space being separated. Sing Sliding folding doors are the perfect match for your sliding stacker doors and can feature any flat surface material including any available natural wood species, aluminum, ceramic tile, cold rolled steel, copper, fiberglass, FRP, galvanized steel, hot rolled steel, Kevlar, LVL, MDF, stainless steel or veneer, just to name a few.

Sing sliding door dividers are pre-insulated with insulation packed throughout to imbue your sliding door partition with added sound deadening characteristics which greatly enhances the overall performance of your Sing sliding dividers. Now you can enjoy both sound dampening and effective control of heat or cold on either side of your sliding partitions.

That’s why you see Sing large sliding doors everywhere on planet earth and beyond, from beneath the sea (US Navy) to outer space (NASA) and everywhere in between.

Sliding Doors

The deal with sliding doors is that you want your sliding doors to remain straight and true throughout their service life. Architects, designers and end users face the issues associated with the problems associated with sliding doors, such as,

Problems with Sliding Doors

The first problem with sliding doors is that they tend to move (warp, bend, twist or cup) compromising the doors’ performance. Especially in the case of sliding doors because they hang parallel to a wall (like sliding barn doors), another door (such as double sliding doors) or within a wall (like sliding pocket doors). If the door does not stay straight, it can wreck either the sliding doors or the surfaces they slide against, or both.

Heavy Sliding Doors

One way to deal with the problem of warping sliding doors is to build them using extremely heavy and warp resistant materials, such as steel, which introduces whole new set of problems, which will increase maintenance costs over the life of the door. Even though the heavy sliding door may not warp, it will require expensive heavy duty hardware (which can cost many times the price of the door itself) which can easily be compromised due to regular use, as well as the added stress of using a heavy door, will add stress and strain to the frame and structure, also requiring additional maintenance over time. Some architects and designers might consider using a lighter weight metal, such as,

Aluminum Sliding Doors

Of course, aluminum sliding doors make more sense; though contemplating the use of solid aluminum sliding doors will still introduce the problem of heavy weight. One way to manage the weight of the door is to use a honeycomb material, such as aluminum honeycomb, paper honeycomb or some other type of honeycomb material inside the otherwise hollow core sliding door. The only problem with that is that as you introduce a lightweight substrate, the door begins to warp again, especially if they are exterior sliding doors.

 

Wooden Sliding Doors

Ah, the elegance and beauty of natural wood. We love it and exotic wood grains can instantly garner the awe and attention of anyone spying a large sliding door made of wood. This is why many large sliding doors are wooden sliding doors. As magnificent and appealing as they are, wood is the worst culprit of all, because it can barely sit still for as long as you can. Due to wood’s natural characteristics, it is most prone to warp, bending, twisting and cupping, because even separated from the tree, it still fights for survival and the grain will either expand or contract due to the elements it is presented with. Exterior doors are the most problematic because one side faces the interior space, while the other side faces the elements outside, a perfect recipe for door warp.

Large Sliding Doors

The bane of perplexed custom sliding door manufacturers is the additional challenges with doors which are taller than 7 ft. tall and wider than 3.5 ft. Very few, if any, custom door manufacturers or millworks will even consider guaranteeing a door over seven feet tall. Why? Because they know it is going to fail, and they will be called upon to deal with it. In most cases, the job as a whole will have a warranty on the work done, with the exception of the large sliding doors which are normally noted as exceptions to any warranty that might cover the rest of the job. That is, unless you know the answer to the problems associate with large sliding doors.

Sliding Door Design Problems Solved

Architects and engineers are constantly perplexed with the problems associated with sliding doors, fortunately an Eco-friendly composite solution made in the USA, helps to solve the problems associated with faulty sliding door design. Patented Sing Core, along with their true flat door team, can help to create sliding doors that will remain straight and true far beyond the service life of any other sliding doors. By working with Sing Core’s design staff a combination of Sing Core and patent-pending sliding door stiffening solutions can create perfect sliding doors that are lightweight, high strength and can be guaranteed not to warp, bend, twist, cup or otherwise fail for 50 years.

The Perfect Large Sliding Doors

The best custom door manufacturers and millworks who offer long warranties on their large doors have a secret inside each one of their high end professional sliding doors: Sing Core inside. A properly designed and built large sliding door with patented professional Sing Core inside can be guaranteed not to warp, bend, twist or otherwise fail for 50 years. How do you know if you have the best large sliding doors in the world?

Image on the left is a modular large 8×10 door shipped in a pair of 4×10 components cam locked together on site for near seamless paint-ready perfection. Image on right is close-up of near-seamless connection.

It’s easy; just see if your sliding doors have the following Sing Core sliding door characteristics:

Eco-friendly
Lightweight
High-strength
High Precision
Fully Insulated
Warp-free
Sustainable Long Life
Made in the USA

When your sliding door company claims they are providing you with the best sliding doors possible, you can rest assured your large sliding doors will pass the perfect sliding door test by being manufactured using Eco-friendly Sing Core which uses less energy, renewable, sustainable and non-toxic ingredients to create its vertical grain torsion box composite core.

The high strength of Sing Core outperforms any other sliding door core material, independently tested to rate at least 660 PSI, which makes it stronger than steel pound for pound.

Other sliding door core materials do not create a high precision base due to product production inconsistencies or welding, while Sing Core is the most high precision at +/- .006 inch. Only perfect sliding doors manufactured with Sing Core inside can remain warp-free. Sing Core is fully insulated imbuing the best sliding doors with climate control (R rating) and sound deadening qualities (STC rating*) for greater safety and security. Professional Sing Core sliding doors can be guaranteed not to warp, bend, twist, cup or otherwise fail (including full structural warranty) for 50 years, assuring your large sliding doors sustainable long life, while being proudly made in the USA.

Yes, you read that right. The perfect large sliding doors are the only ones that have a

50 Year Guarantee

Now you know you have the perfect large sliding doors, if they have Sing Core inside.

Other Types of Sliding Doors

You can enjoy all the available types and styles of large sliding doors that can accommodate and size without compromising strength or weight, such as sliding French doors, patio sliding doors, mirror sliding doors, folding sliding doors, sliding pocket doors, double sliding doors and sliding folding doors, just to name a few.

High quality high end doors will come with a guarantee to ensure the customer’s satisfaction. Most large pivot doors do not come with a guarantee because they are problematic and have a high potential for warping, especially if the pivot door is an exterior pivot door.

In case you didn’t already know, it’s important to know how and why pivot doors fail.

Is your Pivot Door Likely to Fail?

Most pivot doors will fail doe to either the pivot door warping, or delaminating (structure). A composite pivot door (anything other than a heavy solid slab of flat material) will fail due to stress or environmental conditions. Any undue stress or strain on your pivot door, i.e. regular use straining both the hardware and the supporting structure (causing increased maintenance over time) or exposure due to unforeseen circumstances (like accident or abuse) may cause the door to fail or delaminate in response to impact.

What to look for in the best pivot door: Lightweight and structure warranty

Large Pivot Doors Are Prone to Failure

The Architectural Woodwork Institute issues and maintains minim requirements for warping doors which allows for up to ¼ inch of deflection or door warp over a 7 ft. span. Knowing that all doors warp, is helpful when reviewing your expectations in regards to pivot door warping. A warped door seven feet tall is likely to warp up to ¼ of an inch regularly, which is allowable in door warranties.

What to look for in the best pivot door: Oversized, large pivot door warranty

Exterior Pivot Doors Are Prone to Failure

Exterior pivot doors have a higher risk of failure due to door warp because one side (the inside) of the pivot door faces a temperature controlled interior space while the other side is exposed to the elements which cases the pivot door to move (warp, bend, twist, cup) resulting in pivot door failure. If a pivot door cannot freely swing or seal due to being warped, the may not be able to latch or operate as a door due to air leaks around the pivot door.

Why Pivot Doors Fail: 1. Door Warp, 2. Heavy Weight, 3. Structure Failure, 4: Size.

We Do Not Have Pivot Doors for Sale

We do not have pivot doors for sale, because we do not make pivot doors. Our pivot door blanks are used by door manufacturers and millworks to build the best pivot doors. Our patented Sing Core is the only high precision pivot door blank material that can be guaranteed not warp or fail for 50 years.
You can have the best pivot door with the best 50 year pivot door guarantee just by contacting your favorite millwork, custom door manufacturer or door company and tell them what pivot door you want and ask for, “Sing Core inside.”

That’s what we do. We work with the best pivot door manufacturers to make the best pivot doors that have the best pivot door guarantee for 50 years, because your pivot doors have premium Sing Core inside.

That’s why the best contemporary architecture design specifies, “Sing Core inside,” in the most important high end projects, especially when there are large pivot doors requiring high performance expectations over time.

How to determine if Your Pivot Door is the Best of the Best?

1. Warp-free

See the minimum warp allowances for pivot doors below. Pivot doors made of patented Sing Core far exceed the warp resistance allowed by AWI standards. In fact, one of the largest high end door manufacturer comments, “We have not had a single door fail since we started using Sing Core door blanks.”
All the latest multi-million dollar homes are using large pivot doors in their contemporary architecture design. Please inquire with your favorite trade professional as to which pivot doors can be guaranteed to remain warp-free for more than one year. Patented premium Sing Core doors can be guaranteed to remain warp-free for 50 years.

2. Strength

Patented Sing Core is strong enough to withstand the impact of a sledge hammer without causing structural damage. See the unbreakable mirror test, which demonstrates a mirror backed by Sing Core which does not break under the direct impact of a 16 oz. hammer. Your high strength door with Sing Core inside will survive years of use and impact without distortion or structure failure. Patented premium Sing Core is fully structure guaranteed for 50 years.

3. Lightweight

Some of the largest pivot doors could weigh a ton in an attempt to obtain strength and warp resistance but not doors with Sing Core inside. Patented Sing Core weighs approximately 10% of solid wood, timber or plywood core. Products made with Sing Core are stronger than steel pound for pound. Lightweight pivot doors are safer for kids to operate, plus it costs less for hardware, transportation, handling and installation and will not sag after years of use.

4. Eco-friendly

The torsion box structure of patented Sing Core is responsibly and sustainably made using renewable vertical grain natural wood fiber which comes from nature, unlike other less strong core materials made of paper, aluminum or solid wood-based cores.

5. Insulation

Patented Sing Core is packed with insulation which imbues the pivot door with qualities such as climate control and sound deadening characteristics, which is even used in bullet proof and impact doors. High R value and STC rated* insulation material is also a key component in the solid composite substrate which helps to achieve the high performance standards of Sing Core.

“It would have not been possible if not for Sing Core.”

The unique patented vertical grain torsion box/insulation-packed composite substrate expands the possibilities of building materials, bringing the visions of architects and designers to life and is the only Eco-friendly product known with such lightweight (10% the weight of solid wood) high strength (660 PSI) ability to span long distances with little or no deflection, even under stress and strain over a long life of heavy use.

Ask your favorite architect, millwork or custom door manufacturer about Sing Core.

* Note: STC rating varies according to size, thickness, skin, and other factors. Sing Core does not rate doors, although we are fortunate enough to have one of the best sound testing labs in the world, here in the Pacific Northwest. If you require a specific STC rating, Sing Core can build a door to your architectural specifications and have the resulting door tested at our rating facility for an official rating.

Sliding Door Design

Your sliding door design is limited only by your imagination. Architects and designers love adding sliding doors to spaces for visual impact and improved functionality. Many options cover the landscape of design possibilities when considering adding sliding doors to a particular design. Some of the most popular sliding door designs include single sliding doors, double sliding doors, stacking sliding doors, pivot sliding doors, sliding barn doors, floating doors and pocket doors, just to name a few, while large sliding doors may comprise complete sliding walls and may be used as sliding room dividers.

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

Imagine Your Sliding Door Design

The strength of contemporary architecture design is in the creativity limited only by the imagination of the individual envisioning the concept, look and feel of the project at hand. In a perfect world, your sliding door visualizations and ideas translate well to the real world. In many cases what is seen in the mind’s eye exceeds (sometimes far exceeds) the limitations of available building materials, time or budget constraints (because any sliding door design is possible given enough time and money).

Limitations of Sliding Door Design

When translating visionary sliding doors to the real world, certain limitations are imposed on those with their feet on the ground, whose responsibility it is to bring your sliding door dream to life. These limitations include such things as the Law of Physics and the specific characteristics of the available materials used to materialize your most exquisite sliding door design.

Our team of best sliding door professionals have years of experience trouble-shooting and solving the problems associated specifically with unique sliding door designs. Here are some of the problems associated with sliding doors which we can provide solid solutions for (including our 50 year warp-free guarantee) regardless of the size, style or functionality of your sliding door design.

Sliding Door Sizes

Sliding doors, just like any other type or style of doors, vary in accordance with the materials used and the overall size of the door which determines the weight of the door. Large oversized sliding doors, particularly those over 7 ft. tall are so entirely problematic that no door company will warranty them for more than one year because they cannot maintain optimum precision or door performance over time due to the sliding door’s mass. Yet, even large exterior sliding doors with SingCore inside can be fully guaranteed for 50 years not to fail, regardless of size (up to 50 ft.). So, now you can release the previous limitations concerning size and embrace the idea of very large sliding doors, even floor to ceiling sliding doors and sliding partition walls that will make your design shine for years to come.

Sliding Door Weight

Sliding doors best operate within a delicate balance between size and weight, where weight can cause problems associated with the structure, the sliding door hardware, and the regular trouble-free operation of the sliding door. SingCore’s highly specialized staff can help to engineer doors to be lightweight (1/3rd or more the weight) of other solid core doors.

How do you make such a lightweight door? We use patented insulated Sing reinforced vertical grain torsion box core inside which makes the resulting door so much lighter than other solid core doors. Fore instance one door company replaced a series 25 foot tall sliding doors weighing in at 1,100 lbs. with Sing 25 foot sliding doors weighing in at a mere 198 lbs.

Sliding Door Hardware

Next up is the sliding door hardware, which is also most closely associated with the sliding door weight. In fact, the weight of the sliding door dictates which hardware is to be used. In the case of heavy sliding doors, heavy duty industrial sliding door hardware must be used. In the case of heavy sliding doors, the sliding door hardware can be the most expensive part of the sliding door design, costing many times the price of the sliding door itself. Also, regular use of a heavier sliding door will create maintenance problems with the sliding door hardware over time.

Sliding Door Warp

A warping sliding door is problematic in that it can not only compromise the operation of the sliding door itself but also can create additional strain on hardware and damage other surfaces which parallel the sliding door. In the case of a sliding door concealed within a cavity, like a pocket sliding door, a warped sliding door can become entirely inoperable.

This is particularly common in wood sliding doors due to the nature of the natural wood grain; it moves. Even though wood grain is the most prevalent culprit in on site sliding door failures, sliding doors made of other materials may also warp as designers, engineers and contractors attempt to mitigate the problems associated with the weight of heavy sliding doors by creating a lightweight composite sliding door. Though the issue of weight is addressed, the strength of the door is only as strong as its sliding door core material. Therefore, lightweight composite sliding doors made of other materials besides natural wood are subject to failure due to warping also.

Sliding Door Solution

SingCore is the premiere one-of-a-kind solution to all problems associated with sliding doors, eliminating the challenges of:

WEIGHT – HARDWARE – WARP

While adding attribute inherit with having patented SingCore inside, such as

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.

Such as issues in the tallest of buildings, not only in New York (where most of our product is shipped to nationally) but across the ocean, like in this, one of the tallest buildings in Bangkok, Thailand.

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.

The precision of SingCore as a building material is +/- .006 inch, which makes it a standard for high precision clientele such as NASA and the United States military. The strength is unmatched by any other affordable lightweight material (660+ PSI), making SingCore stronger than steel pound for pound, enabling this material to cover long spans with little supporting structure and deflection, achieving a new standard for less deflection under loads and warp resistance.

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.
