Interior view of extremely large pivot door with hardware
Case study:
A 55” wide x 19’ tall x 3.25” pivot door. With differing Cedar and oak wood stave skins.
Being approached by a client who is in need of a uniquely large pivot door to withstand the difficult climates of Lake Tahoe can seem like a near impossible feat. This pivot door needed to be lightweight for ease of installation and daily use by the client, impact resistant to hold up to everyday use, sound deadening to drown out the hustle and bustle of everything outside
A pivot door built with patented and patent-pending SingCore inside can make anything possible.

Opposing wood species
Dissimilar wood species on the interior and exterior of the door means differing rates of expansion and contraction. SingCore has the strength and stability to remain rigid against the push and pull of the dissimilar skins.
Lightweight oversize door
Lightweight
Now let’s take a look at why this door needs to be lightweight.
First off, big pivots doors tend to be very heavy which makes them more difficult to manage, they require custom made specialized hardware and require a lot of maintenance due to the stress that the pivot door adds to the structure.
Secondly a pivot door is only held with two points of contact on the top and bottom of the pivot door; meaning that if the door warps or twists, the door operation will be degraded or completely fail.
A pivot door this size with a solid core will weigh around 800lbs before any skins are added.
Now with SingCore, this door’s weight is a fraction of what other solid pivot doors would have weighed. This weight savings translates into a reduced overall budget by having lower shipping costs, lower hardware cost and lower cost for the labor of the installation.
Adverse climate for keeping oversize pivot doors straight
Ready for any climate
Lake Tahoe is known for its incredible skiing and breathtaking beauty. Not for its temperate climate.
This pivot door will see outside temperatures as low as 4°F while the inside temperature may be a toasty 76°F, which is a 72° difference.
SingCore pivot, sliding, hinge, and pocket door slabs are fully insulated with your choice of recycled EPS foam core (3.5 R value per inch) or urethane foam core (5.7 R value per inch).
Perfectly straight oversize pocket door
Straight
At 19’ tall this pivot door is as big of a challenge as it gets to keep straight.
All door slabs fabricated by SingCore are completely custom. The SingCore team takes into account the finishing, hardware, and climate when building each core. No two doors are alike. And we take great pains to ensure every pivot, sliding, pocket, and hinge door stays within AWI standards.
We love creating one of a kind oversize doors that no one else can.

Pivot doors make an impact which does not fade quickly. We specialize in working together with the elite high-end millworks and exclusive custom door manufacturers to create breathtaking custom high-end pivot entry doors for the most discerning clients in the United States and abroad.
Specializing in large opening doors is a craft which until recent years presented immense challenges for architects, designers, and engineers when it comes to creating large pivot doors which are taller than eight feet or wider than four feet due to the limitation of the building materials available at the time.
Now, Sing Core presents a pivot door blank which empowers any visionary pivot door company to bring their large pivot door dreams to life. This has ushered in a whole new series of highly individualized one-of-a-kind pivot doors, each one is a specially crafted pivot door which may be similar to, but clearly unlike any other door, making their way into the most exclusive designs and structures around the world.
You can find pivot doors with Sing Core inside just about anywhere from beneath the sea (US Navy) to outer space (NASA) and everywhere in between. This is no surprise when you take into consideration that this is the only way to make large pivot doors which are lightweight, fully insulated, and fully resistant to warp.
Sing Core’s hinged doors and pivot doors are a growing trend among modern door companies, contemporary architecture, and design aficionados who are on the leading edge of the wide range of industries which they represent.

It’s hard not to pass through such a large opening without expressing one’s self, with something, like, “Wow.”
Until the advent of Sing Core, the resounding challenge facing pivot door manufacturers was the fact that pivoting doors were warping. Thanks to inventor, Peter Sing, his factory is able to build warp-free pivot door blanks custom-designed and built to host any flat building material. This non-warping substrate enables any pivot door company to build a pivot door that does not warp.
In fact, custom built doors, built in tandem with Sing Core’s true flat team can provide clients with pivot doors which can be guaranteed not to warp, bend, twist, or otherwise fail (including full structure) for 50 years; guaranteed in writing. No other door builder can do that, unless their doors have Sing Core inside.
Unlike hinged doors which are firmly anchored on one side of the door to help prevent warping, pivot doors only have two points of contact where the door swings freely from side to side, in some cases all the way around, pivoting on one anchor point on the doors base and the other on top of the pivoting door.
That’s it. Therefore, it’s very hard to keep pivot doors straight. Sing Core provides pivot doors such as aluminum pivot door and steel pivot doors, but also dares to build and create warp-free versions of wood pivot doors, which are by far the most problematic.
Glass and metal pivot doors provide the least amount of problems, yet architects and designers still specify Sing Core to reduce the weight and increase the insulation value of the metal and glass pivot doors to reduce sound and increase thermal capabilities for the best of all pivot doors available today.

How to Spec a Pivot Door
Best way to spec your large pivot door is to note that it has to have, “Sing Core inside.”
Sing Core works hand in hand with millworks andcustom pivot door manufacturers to create the ultimate pivot door. It starts with Sing Core inside.
Sing Core is a revolutionary pivot door core. Patented and patent-pending technology created by inventor Peter Sing. The core is a reinforced torsion box, creating a solid composite structure. Lightweight Sing Pivot Doors are insulated, sound-deadening, and custom built.
If you want to find the best door in the world for you next project all you need to do is to use the best tool for finding the best doors, such as:
Google search pivot door
If you’re looking for the what constitutes the best doors, then you might search for the most expensive door. You will find that the door companies which can make the most expensive doors which outperform all other doors in terms of weight, strength, and longevity are the hardest to make. That is, unless you know the secret.
Best Door Secret
Pivot doors are problematic because they only have two points of contact whereby the pivot door is operated and anchored by the pivot door hinges.
Hinge doors can be secured by multiple hinges, even a full length piano hinge which anchors one whole side of the door completely. Even so, with one side fully anchored, a large door will warp, bend, twist or cup, causing it to fail. A warped door will compromise the door seal and may not be able to allow the door latch to secure properly.
High End Pivot Doors
Pivot doors rely only on those two pivot points, one on the top of the door, and the other opposite it on the bottom of the door. It is imperative for a functioning pivot door to remain straight and true, or else you cannot operate it properly.
Only the best pivot door companies can make a high-end pivot door which can perform over time without failing due to door warp.
50-year Warp-free Guarantee
All you have to do, is to contact the top pivot door manufacturers on your search results and ask them if they offer a large pivot door with a 50-year guarantee.
If they do, these doors will all have Sing Core inside.
With Sing Core inside your pivot door, it will be lightweight (a fraction the weight of other solid core pivot doors), and high-strength (at 660+ PSI, stronger than steel pound-for-pound).
9 ft wide warp -free weatherproof pivot door
You also have the added benefit of having a pivot door which is fully insulated for climate control and sound deadening capabilities (Sing Core can be found inside the most efficient soundproof doors in the world).
You Can Laugh or Cry
When you discover the secret of the most expensive high-end doors, you might start to laugh, but before you start laughing, think about this:
You might be crying, if you make the wrong decision, and find yourself in possession of a weak door which may fail prior to when you might have expected.
This is why most large door manufacturers will exclude large doors (over 7 ft tall and 3.5 ft wide) in the door schedule from the warranty following installation. Chances are they will start to fail at the next change of season.
21 ft tall aluminum pivot door
Then you might reason (as many have) that if Sing Core can make the best doors in the world the most valuable doors in the world, then Sing Core could make anything better, and it does.
Doors and So Much More
Entire homes have been made of Sing Core, which is available in post and beam and panel formats, changing the way homes are built, including all the interior and furniture inside a Sing home.
Sing Core makes everything better and its Eco-friendly nature makes everything more sustainable over time.

Insulated Walnut Door
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.
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.
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.
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.

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.
