What Is A Pivot Door?

A pivot door rotates on a pivot box in the floor and the top jamb rather than traditional door side hinges, which is common in most homes. Pivot Doors have become a popular choice for entrances, creating a bold statement at your first point of contact.

What makes pivot doors so unique? The pivot door or pivot window is an opening system with a central or lateral rotating axis that allows for very large door panels. The craftsmanship and technology of a pivot hinge allows for a larger opening than most other types of doors since traditional hinges cannot carry the same kind of weight. Pivot doors are fantastic options for where there is a large amount of space and enough floor room for the door to be able to swing all around.

Grounded in the principles of modern architecture, a pivot door emphasizes clean lines and simple shapes. Pivot doors are well suited for pivoting walls and can also be used as room dividers. Until now, affordable pivot doors are thicker than average doors and heavy in weight. The large size and heavy weight causes extra costs associated with shipping and handling. Shipping is more expensive because shipping costs are calculated on weight. Handling is more expensive because heavy equipment is necessary for transporting and manipulating the pivot door into place for installation. Pivot door hardware is also based on the affordable pivot door’s weight, so a heavier pivot door will require more expensive and heavy duty hardware. Here at Sing Core we manufacture custom premium wood pivot-hung entry doors for exterior and interior use. Our pivot doors feature our patented lightweight insulated torsion box pivot door core inside. Which imbues each door with the unique characteristics of a solid core pivot door featuring the exact size, material and appearance of any style of pivot door, while remaining extremely lightweight and incredibly strong. Independently University tested at 660 PSI, makes Sing Core’s pivot door core stronger than steel pound for pound. The pre-insulated core also means greater climate control and noise cancellation between spaces. Also, the lightweight of Sing Core’s pivot doors, means less shipping, handling, transportation and installation costs, requiring less expensive hardware.

A pivot, not a hinge rather than hanging from hinges in the frame, a pivot-hung door swings on a set of pins mounted in the top and bottom of the door. Transform the look of your home or office by opting for Sing Core’s affordable pivot doors. Pivoting front entry doors provide an elegant look and appear to float inside the door frame. We are offering premium wood pivot-hung entry doors for exterior and interior use that cannot be found anywhere else. Let Sing Core build your custom pivot doors, custom modern entry doors, exterior mahogany wood doors, or any other custom door you can imagine! If you can create the idea, we can create the door. Every Sing Core door comes with a 50 year structural guarantee, something that no other door company has been able to offer.

Pivot Door 50 Year Guarantee

There have not been many truly significant advances in the manufacturing or pivot doors in the last hundred years, until now, with the invention of patented Sing Core which offers the only pivot door 50 year guarantee for a large custom eco-friendly lightweight high strength door.

Such a door could not be built before. In fact, when the largest door companies were approached with building a large custom pivot door, they turned the job away, because while such a door could be built and look spectacular when installed, it would not be long and the door would fail.

Large custom pivot doors were manufactured by high end millworks willing to do the work and charge the prices commensurate with a high degree of craftsmanship with reliable regular maintenance over the life of the door because the key to making these large pivot doors work over time would require a heavy maintenance schedule to straighten the doors that were known to warp and need repair periodically (potentially every change of season depending on the climate and geographic location of the big pivoting door).

This was the case of every large pivoting door over three-and-a-half feet wide and seven-and-a-half feet tall, especially if they were large wooden pivot doors. Natural wood tends to want to move according to any change in the environment. The result? Large warping pivot doors.

Enter inventor Peter Sing’s patented large pivot door core which empowers high end millworks and the biggest door companies in America to build the biggest lightweight high strength pivot doors in the world that can be

Guaranteed Warp-free for 50 Years

Inventor Peter Sing created a hybrid composite core and anti-warp technology to build large pivot door cores that could support the weight of any exterior material and stay straight and true. Sing’s True Flat Team helps to design and create the perfect door base material to accomplish the goals of the architects, designers, door engineers, artists, and end users, with no risk of warping doors.

The technology is based on a melding of new and old technologies using Sing’s out-of-the-box approach to problem-solving. Start with a basic torsion box design (traditional method of building large flat wooden products) but flip the grain of the torsion box frame on its side so that it lays perpendicular to the stress skins. Then before you apply the stress skins fill all the empty cavities inside the torsion box structure with rigid recycled foam. Cold-press with formaldehyde-free glue for a basic warp-free base material.

That’s the basic formula, but there are type of woods and other building materials which have a greater propensity to warp than others. Sing’s True Flat team reviews each door and determines if extra patented and patent-pending anti-warping technologies will have to be added to the door to keep it from warping, especially if it has a surface material with a greater potential to warp.

The Warp-free Pivot Door 50 Year Guarantee

Is a science which Sing has mastered. And just when you thought that might be all you might expect from any pivot door with Sing Core inside…

But Wait. There’s More…

All of Sing’s pivot doors also have an impressive list of features that you would be hard-pressed to find anywhere else, except for Sing’s factory located deep in Washington State’s scenic Pacific Northwest. They also offer,


For added safety and security for you, your family, at work, in scientific, government, and military applications. This is why you see Sing’s core specified in the best soundproof doors.


At least R3.5 per inch (R-value can be increased to match your performance expectations) of Sing Core give’s you more separation from the elements or greater temperature control in heating or cooling environments.


If you are looking at a lightweight high strength building material, Sing’s core can meet or exceed your precision expectations as it hosts high tolerances throughout (+/- .006 in.).


In side by side comparisons, pivot doors with Sing Core inside require less maintenance over time than any other door because, simply stated, they do not warp, cup, bend, twist, not otherwise fail.


Sing’s doors are designed and built to last for centuries but guaranteed to perform fail-free for 50 years. No other eco-friendly lightweight high strength material can do that.

Add to those characteristics, the following attributes:


A fraction (at least one-third less) the weight of other wood-based cores or their alternatives.


Able to span long distances and carry loads with little or no support. Unbelievable unless you’ve had the opportunity to handle a Sing door first-hand.


No other material can compare to Peter Sing’s uncanny ability to build doors that just will not warp. Sing Core is the reason door companies, millworks, and custom door manufacturers are back in the business of building large pivot doors again.


The only door in the world guaranteed not to warp, fail, or delaminate for 50 years.

This is why more and more you are able to find Sing’s patented tech anywhere from beneath the sea (US Navy) to outer space (NASA) and everywhere in between.

Join the Sing Revolution today, for a better world.

High End Pivot Doors

Sing Core goes through great lengths to provide the best architects and millworks with the best high-end pivot doors in the world. High end pivot doors stand out because they are generally massive in size which can be problematic for engineering a door which performs flawlessly over time.

Unlike hinged doors, your pivot door rotates on a pivot box, which only has two anchor points, whereas a hinged doors has three anchor points on one side of the door which helps to keep the door straight.

Sing Core assures clientele that they possess a high-quality pivot door that can be guaranteed not to warp, ben, twist, or otherwise fail for 50 years. Astonishingly, Sing Core can design huge wood pivot-hung entry doors that can also be guaranteed not to warp. (Something unheard of in the door industry until the invention of Sing Core.)

Inventor Peter Sing’s patented high-end pivot door core makes all the difference. Sing’s factory is not a door manufacturer, instead his factory provides the best door manufacturers, millworks, and custom pivot door builders with the base material which makes the highest standard of large pivot-hung entryways possible.

Exquisite cooperation in design and quality construction while working with a team of architects, door designers, engineers, manufacturers, finishers, and installers assures that Sing’s Eco-friendly high-end pivot doors possess the following attributes:


High Strength

Fully Insulated

50-year Warp-free Guarantee

Sing’s pivot doors weigh so little that millworks and door manufacturers are amazed that two people can easily maneuver a 20 ft wide pivot door blank. It is something you can’t quite understand until you are actually holding it in your hands.

These patented Sing cores are so strong, you can see Peter Sing standing on this 13 ft long one-inch thick panel with little or no deflection. Imagine what you could do with Sing’s core.

The pre-installed rigid insulation offers added safety and security, sound deadening, and increased climate control.

And what you get in the end is a pivot door that is prefinished with high-end craftsmanship that looks like a huge solid wood pivot door, and only you will know that it has Sing’s secret pivot door core inside.

This is how the highest quality pivot front doors are made.

Generally, large pivot doors are quite thick, which leaves anyone who encounters such a door with a striking first impression, which is imprinted in nearly everyone’s brain, and they will be found later telling stories about the enormous pivot door that articulated with such ease. Even so, Sing’s core is so lightweight and strong that you can create a high-end ultra-thin pivot door, if necessary.

The Sing Core pivot factory can also preconfigure your high-end pivot door with any type or style of custom lite opening. You can feature several lite openings for a particular design effect, or one large opening for that French door feeling that maximizes pivot door views of the outdoors and/or neighboring landscapes.

Peter Sing’s philosophy is one of simple beauty and lasting quality with an unparalleled guarantee which cannot be achieved with any other lightweight pivot door core, until now, thanks to his invention.

While most of Sing’s pivot doors are designed and built of wood, many are built of metals, such as aluminum, steel, and other types of metals including bronze pivot doors, and could be made of nearly any flat building material.

If you want the best high-end door with the best guarantee, maybe you should think about talking to your architect about having Sing Core inside your pivot door.

High Precision Warp-Free Metal

Sing Core provides lightweight, high precision, and warp-free metal products to industries; such as military, aerospace, construction, high-end millworks, and door companies in panel or post and beam configurations.  These configurations are stronger than steel pound for pound and are guaranteed not to fail for 50 years.

Inventor Peter Sing provides his patented and patent-pending weldless metal technologies to solve the problems associated with the limitations of metal products.  Welding causes imperfections in the surface area and compromises strength.  Solid metal can look very nice but is so heavy.  It is highly impractical, expensive to handle, install, and the cost of hardware is outrageous.

Warp-Free Metal Doors

Oversized metal doors are a challenge for architects, designers, and engineers.  Standard-sized metal doors can even be a challenge, depending on your expectations.  The bigger a metal door is, the more problems you will face in; the building, transporting, installing, and ongoing maintenance of the door, hardware, and structure over time.

Sing Core’s solution solves the problems associated with metal doors by offering their patented alternative to traditional metal door manufacturing methods.  Thus resulting in the highest precision large doors in the industry with the highest performance across the board for lightweight and Eco-friendly metal doors.  So far advanced that each door is guaranteed to remain true flat and fail free for 50 years.

Looks Like Solid Metal

Whether your metal doors are made of; aluminum, brass, cold rolled steel, hot rolled steel, copper, diamond plated steel, galvanized steel, stainless steel, or any other metals you can think of.  When you encounter one of Sing Core’s metal doors, it looks and feels like a piece of solid metal, but achieves the high-end precision and performance that any other type of metal door cannot achieve.  If your metal doors need to be precise and true, it must have Sing Core inside.

Sing Warp-Free Metal is

Eco-friendly Lightweight  High Strength
Fully Insulated  Sound Deadening  Climate Control
High Precision  High Performance  Guaranteed 50 Years
Impact Resistant  Hybrid Composite  Solid as a Rock

Compare Your Metal to Warp-Free Metal

Standard Metal  Sing Warp-free Metal

Strength Variance  Stronger than steel lb. for lb.
Inconsistent Tolerances  Sing Core Tolerance +/- .006-in.
Inconsistent Surface Area  Perfectly Smooth as fresh-milled
Expensive Hardware  Less Expensive Hardware
Expensive to Install  Save $ on Installation
Increased Maintenance  Little or No Maintenance
Potential to Fail  50-year No Fail Guarantee

If you’ve worked with long spans of metal, you know the limitations of how metal performs.  Take a look at inventor, Peter Sing, standing amidst a 13 ft. span on an aluminum panel that is only one-inch thick.

Inventor Peter Sing standing on a one-inch panel 13 ft. span w/little or no deflection

No other metal panel could perform like this.  Only warp-free Sing Core metal panels could accomplish such a feat and remain just as lightweight and strong for 50 years without fail.  This has been unheard of, until now.

Pivot Entry Door

When it comes to large entrance doors, one pivot entry door comes to mind: That beautifully big pivot entry door with natural wood grain is so pleasing to the eye.

Q: How in the world do they keep such an enormous exterior wood door from warping?
A: With Sing Core inside.

Large entrance doors instantly garner attention and add curb appeal to any project, but featuring pivot doors as your entrance door makes an even greater impact on anyone who encounters such an enormous work of art.

Pivoting doors are more in demand because they attract attention like a magnet, especially if your pivot entry door is made of natural wood grain, because this just cries out: “Constant maintenance required” due to changes in the environment which causes such a big wood pivot door to warp. It doesn’t make the pivot door any less beautiful, but the regular maintenance can make such a door far less affordable over time.

That’s where patented Sing Core and inventor Peter Sing’s patent-pending anti-warp devices come to save the day. Sing, also the president of Sing Core, uses his latest technological advancements to help any pivot door company, millwork, or custom pivot door manufacturer build pivot entry doors of immense size quickly and easily without threat of failure or warping.

The idea of a new generation of warp-free modern entry doors is foreign to pivot door designers and engineers of yesteryear, that is, unless they have already heard about – and use – Sing Core inside their most important pivot entry door jobs.

How to Build a Warp-free Pivot Entry Door

Solid wood entry doors present the greatest numbers of challenges for the craftspeople tasked with transferring the architectural pivot door dreams into reality. We love the natural wood grain but it’s tendency to move at the slightest change in the environment creates problems. So, starting with Sing Core is the perfect place to start if you want to put your worries associated with exterior pivot doors behind you.

For years, Sing has been supporting the best of the best in contemporary architecture and designs, as well as the biggest most powerful pivot door companies in the world with the solutions to the problems associated with pivot entry doors over seven ft tall and three-and-a-half ft wide. Once you know how Sing’s core works, you, too, will know how to build a warp-free pivot entry door.

If you look deep inside the structure of Sing’s warp-free pivoting doors, you will find that the first component is torsion box, only the grain is oriented vertically instead of horizontally as is the case for traditional torsion box. Sing also keeps the structure grids of the torsion box very small, like two to three inches. Then, he fills the voids (the open centers of the individual torsion boxes which is normally left hollow) with recycled rigid foam.

Using formaldehyde-free adhesive, Sing cold-presses the composite materials together, sandwiched between two stress skins to create the solid hybrid warp-free pivot entry door blanks which are found inside the best high-end doors.

Even so, Sing’s warp-free technologies do not end there. Pivot entry doors are especially challenging due to potentially having one side of the door facing the elements, as in the case of exterior pivot doors, while the other side faces the structure’s interior. This is the perfect recipe for warping pivot doors.

Sing has a True Flat Team of door engineers in-house who assist in the design and creation of the core in such a way so as to account for all the challenges each pivot entry door may face. For instance, solid wood entry doors present the most problems, but not for Sing’s team.

Wood Entry Doors

They go to work, taking into account all the details of the door, including how the door will be used, what direction will it face, at what altitude will it make its home, what weather conditions will it be subject to, how will it be operated, suspended, and secured? As well as what

Sing Core can be found inside modern entry doors from beneath the sea (US Navy) to outer space (NASA) and everywhere in between because it is the highest precision (+/- .006 in.) Eco-friendly fully insulated (R3.5 to R6.5), lightweight (1/3 or less the weight of other solid wood-based cores), high strength (660+ PSI, stronger than steel pound for pound), impact resistant, climate control, and sound deadening pivot door substrate.

Any of Sing’s pivot doors could be made from any flat building materials, such as any type of natural wood grain, aluminum, brass, cement, concrete, cold rolled steel, copper, fiberglass, Formica, FRP, glass, HPL, Kevlar, laminates, Masonite, MDF, stainless steel, veneers, and just about anything you could imagine.

Also, your pivot entry doors are not limited in size, as Sing’s door blanks are featured in really big pivot doors up to 50 ft or more, and each can still be covered by Sing’s 50-year warp-free guarantee.


Sing offers the only way to build doors in the world which can be safely and securely guaranteed not to warp, bend, twist, cup, or otherwise fail, (including full structure warranty and guaranteed against delamination) for a full 50 years.

This is the best pivot entry door guarantee in the world, another reason why biggest and best door makers use it.

The world is changing, growing, and expanding at a rapid rate, and Sing’s pivot doors are changing the way architectural pivot doors of any type or style are being made.

Pivot Front Door

By far, the best pivot front door in America, and around the globe, are pivoting front doors with patented and patent pending Sing Core inside. What makes these pivot front door so special? According to inventor, Peter Sing, there are many benefits which culminate in the only pivot entry door made that comes backed with his 50-year warp-free guarantee, which also covers full structure integrity.

Sing’s core has captured the attention of the best and most well-known contemporary architecture and design aficionados in the world as well as the biggest and best door manufacturers, especially in the arena of the largest oversize pivot front door projects for the most discriminating high-end clientele.

What makes a Sing pivot front door so extraordinary?

The secret of what makes this unique modern pivot door “sing” is Sing’s patented insulated reinforced vertical grain torsion box solid hybrid core which makes each one of these specially designed and built pivot entrance doors an infallible safe and secure urban front pivot door. These modern pivot entry doors are the only pivoting front doors which are built to last for centuries, no matter what the size.

Sing’s patented manufacturing methods and inner hybrid structure core creates a high performance pivot door substrate which imbues each Eco-friendly pivot front door with incredible attributes including (but not limited to) being high precision, fully insulated, lightweight, high strength, and warp-free (guaranteed for 50 years).

Large Pivot Front Door

Here is the part that is making the biggest impact in the large pivot door segment around the world. Mr. Sing’s company is able to provide all those impressive characteristics to those seeking to build doors of enormous size, and still remain Eco-friendly, while exhibiting unparalleled dimensional stability with the highest precision, insulation, lightweight, high strength, and Sing’s 50-year fail-free guarantee.

Even if it’s a pair of 50 x 20 ft industrial doors that are 7-inches thick to cover a high security 50 x 40 ft door opening; Sing’s True Flat Team can jump in and create a solution, like 50 7-inch thick modular 4 x 10 ft components which can be easily transported to any location to be assembled onsite, and still be guaranteed not to warp and possess all of Sing’s core values.

Let’s take a closer look at Sing’s pivot entry door characteristics.

Insulated Pivot Front Door

Every modern pivot front door with Sing Core inside is fully insulated for both climate control and sound dampening. Standard R-value is R3.5 with an upgrade option of R6.5 per inch of pivot door thickness. So, in the case of an upgraded 7-inch thick large oversized pivot door, it would rate at R45.5 (+ the R-value of the skin), while still retaining all the rigidity, strength and light weight of any other Sing Core-based pivot door.


This is another reason you find them in sound proof applications due to the sound dampening capabilities and the ability of the substrate to withstand hosting a heavy exterior material without having to compromise the dimensional stability of the door.

High Precision Pivot Front Door

You can now have a pivot front door of any size with impeccable high precision as Sing’s core boasts .006-inch tolerances. This is of huge interest to those in high-tech industries from scientific and aerospace to military and space-tech. When high precision is keenly imperative to maintain throughout the service life of your aluminium pivot entrance door, which in Sing’s world accounts for at least 50 years, then having Sing Core inside is imperative.

This is one of the reasons you can find Sing Core anywhere from beneath the sea (US Navy) to outer space (NASA) and everywhere in between.

Lightweight Pivot Front Door

Architects, door engineers, and custom large pivot door manufacturers have struggled with finding the balance between weight and strength while trying to maintain dimensional stability, especially in oversized exterior pivot doors.

Prior to the invention of Sing Core, doors of enormous magnitude that could maintain some degree of dimensional stability were not only large and massively difficult to handle on the job site, but nearly impossible to ship to any location due to limitations of transport vehicles and roads (unless you are the military. They can move just about anything from here to there).

Now, thanks to Sing Core, you can have a door that is lightweight (one-third the weight of any wood-based pivot door core or less) and dimensionally stable.

High Strength Pivot Front Door

No more compromising weight for strength. Prior to the invention of Sing Core, the paradigm was, “the heavier the core, the stronger the door.” This is no longer true.

Inventor Peter Sing standing on 1-inch 13 ft. long panel strength demonstration

The brilliance of Sing’s patented insulated reinforced torsion box hybrid core has made a huge impact in relation to archaic building materials, especially with those associated with large sizes, panelized, or post and beam configurations, and spanning large distances.

Sing’s modern pivot entry door cores are lightweight and stronger than steel pound for pound and have been independently tested and rated at from 660 PSI and up.

Warp-free Pivot Front Door

And finally, the most amazing feature of Sing’s doors is that comprehensive 50-year warp-free and full structure guarantee, which is almost incomprehensible.

Regardless of any guarantee that any other door manufacturer may provide (usually 1-year or less) Sing doesn’t even flinch at his ability to guarantee his doors for 50 years because he is confident that every door he builds is built to last for “centuries,” and apparently when it comes to building a sustainable low maintenance fail-free door, according to Sing’s clients,

“There is no other way to do it.”

How to Build a Pivot Front Door

So, if you want a modern pivot front door that’s built to last forever, is fully insulated, lightweight, stronger than steel, and “guaranteed not to warp, bend, twist, or otherwise fail,” for 50 years, there is only one company who knows how to build a pivot front door of such magnitude, and that’s with
