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.
Among the pivot door industry, the millworks, custom pivot door builders, and every major pivot door company, the new buzz words in the world of pivot doors includes the request for high end pivot door to have, “Sing Core inside.”
You might wonder why the trend of contemporary architects and designer are specifying their pivot doors, especially if they are large pivot doors, have, “Sing Core inside?”
The reasons include the attributes of patented Sing Core that are transferred to the pivot door making the lightest weight pivot door (a fraction of other solid pivot door cores, that are also the strongest (independently University tested at 660+ PSI) insulated pivot doors every built.
Thanks to inventor Peter Sing’s patented pivot door core material, any pivot door company can build a large pivot door that can be guaranteed to remain warp-free for 50 years. Pivot doors with patented Sing Core inside are the only pivot doors that can be covered by Sing’s 50-year warp-free guarantee.
Unique pivot doors of all kinds can be built with this revolutionary new pivot door core material, including but not limited to the following pivot doors:
Pivoting Pocket Door
A modern pivoting pocket door presents certain challenges for architects and designers, such as being heavy in weight if it is a large pivot door which swivels and retracts or is stored in a pocket door cavity within a wall. The pivoting pocket door is basically a pivot sliding door which pivots and slides into the concealed pocket. If slide and pivot doors have the slightest warp, bend, or twist they can become inoperable or might be lodged inside the pivoting pocket door’s recess.
Having Sing Core inside ensures the pivoting pocket door will remain faithfully straight and true for the life of the door or 50 years, even though it was constructed to last for hundreds of years.
Pivot Front Door
A pivot front door is also an architectural challenge if it is large, and all the best pivot doors are large pivot doors because the larger they are, the more likely a pivot door is going to fail due to warping. If one side of your pivot entry door faces the structure’s interior space and the other side faces the exterior, exposed to the weather 100%, you’re going to experience a warped door.
Exterior pivot doors do present a problem for the end user and an opportunity for ongoing pivot door companies who specialize in long term maintenance and repair over the life of the door. A well-hung pivot door with Sing Core inside will outperform any other commercial door, hands down. Even if it is among the family of,
Wooden Pivot Doors
Wooden pivot doors present the most problems with warping due to the nature of the wood to move according to the varying climate conditions or change of seasons. Seasonal warp is expected for wooden pivot doors of all kinds, whether they are exterior pivot doors or internal pivot doors.
Patented Sing Core is the only way to build a wooden pivot door that doesn’t warp with all the elegance and charm of solid timber pivot doors but at a fraction of the weight saving you money in pivot door hardware and maintenance over time.
Thanks to Sing Core you can have a large pivot door made of any available natural wood material, which is even a ecologically sound use of exotic wood to create the most impressive exotic wood pivot doors, which is subject to availability, of course.
Pivot Doors Prices
Sing Core’s pivot doors prices will have you expecting to pay more than a traditional pivot door, though in the standard range of high end custom pivot doors. As our favorite architectural door designers know, when you client demands the best pivot door made, it must have Sing Core inside your pivot door.
And while your custom pivot door might represent those among the higher pivot doors prices, you can be proud to have an economical pivot door investment which will pay you back in savings in maintenance, repair, and replacement costs because your Sing pivot door can be guaranteed for 50 years.
Pivot Door Systems
Sing Core is known around the world for providing the best pivot door systems, but the truth is, we don’t actually make the world’s best pivot door systems. Who actually makes our doors the best pivot doors in the world, is the pivot door company, custom pivot door manufacturer, and millwork who makes our patented pivot door core material look so good after they’ve finished and installed these magnificent masterpieces.
Pivot Front Doors for Sale
If you really want a pivot door with Sing Core inside, all you have to do is to contact your local custom pivot door manufacturer, millwork, or wherever you find pivot front doors for sale and make sure you tell them you want Sing Core inside your pivot door.
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.
Beautiful Pivot Door made with Sing Core
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.

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.

The Sing Core substrate material is created using a vertical grain natural wood torsion box design while the traditionally empty voids are filled wall to wall with recycled foam. The foam material is available in various forms depending on your specification. The default is recycled EPS foam. Natural wood lock blocks can be positioned at locations as necessary for locking mechanism placement and/or as pivot hardware anchor points.
