Standard Sing Core Cold Rolled Steel Pivot Door Blanks are manufactured with patented Sing Core material as the base interior substrate of the 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. The core material is framed by 1.25-inch wood stiles and rails for finishing strength and attaching hardware. The torsion box is completed by adhering 20 gauge cold rolled steel as exterior material (skin) according to your specifications. The man door opening is cut out to architectural specifications.

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.
Pivot doors are the number one type of doors built with SingCore inside, especially if your pivot door is a large, oversized one that could present problems for those tasked with building, installing, and maintaining a pivot door of such magnitude.
Why?
Those big pivot doors are heavy, hard to manage, require specialized hardware, and have increased maintenance schedules as they add stress and strain to the hardware and structure if in regular use. The biggest pivot doors have huge potential to cause problems for the end user by warping and requiring regular maintenance, plus they must float, perfectly balanced between two points of contact. The smallest variance can render the pivot system inoperable.

Why Do You Need Sing Core Inside Your Pivot Door?
Pivot Door Problem
It’s well-known pivot doors fail more often than hinged doors because there’s only two points of contact on a pivot door. On a hinged door there are three or more anchor points on one side of the door to help keep the door straight. If a pivot door warps, bends, twists, or cups, the operation of the door can be severely compromised or fail altogether. If you have a large pivot door (over 7 ft. in any direction) failure is far more frequent.
Pivot Door Solution
THAT is why you need Sing Core inside your door. Using Sing Core is the only way to build a lightweight pivot door that is stronger than steel which comes with a full warp-free and structure guarantee for 50 years.

The Best Guarantee in the Pivot Door Industry
50-year warp-free guarantee
50-year structure guarantee
Designers and Architects are establishing a new trend in the architectural impact of structures that garner attention at first glance by greeting visitors with a large pivot door. The larger the front pivot door, the more impressive and attention-grabbing.
Large pivot front doors create the greatest impact when a structure is seen for the first time. These oversized pivot door are big and thick, and the bigger the better. These big pivot doors are taller, wider and heftier than other traditional front door styles. Even real estate developers are installing large pivoting entry doors in high end homes for that extra hit in the curb appeal presentation.
Though some door manufacturers build and stock standard pivot doors, ready to install, the high end large pivot doors are custom manufactured for each installation by millworks, craftsmen or custom door manufacturers. Each pivot door is like an individual work of art.

Pivot Door Swing
Pivot doors are often thought of as having a center pivot point. A pivot door with a center pivot defines the maximum access as basically one-half the door width, because in the fully open position, the pivot door blocks the center of the opening due to the location of the pivot. Large pivot doors may have no problems as a 10 foot wide pivot door can still have a 5 foot access opening.
Center pivots are not your only options when considering a pivot door, as the pivots can be placed at any location. Moving the pivot point of your pivot door more to one side or the other creates a greater egress area on one side than the other. For maximum opening, an extreme edge pivot point can be used for your pivot door, so that it operates very similarly to a swing hinge door. Example: 10×12 extreme edge double pivot doors in the Center for Architecture & Design, Seattle, Washington are each twelve feet wide, five inches thick and open for a full 23 feet of access (also feature a man door for easy access when in the closed position).
Tall Pivot Doors
A large pivot door can span from floor to ceiling of any structure as well as being very wide and thick.
Pivot Sliding Door
Another growth segment in pivoting doors is a method that combines the best of two types of door hardware to develop a pivot sliding door using multiple floor to ceiling pivoting door panels alternatively hinged and retrofitted in sliding door hardware to produce large accordion door wall systems. These pivot sliding door wall units create complete separation between any two rooms, functioning as folding stacking doors, yet when fully opened reveal one large space.
Pivot Door Materials
Pivot doors can be made of any flat building material including materials that would be impossible to make a hinge door due to the weight. The design of the pivoting hardware can accommodate a pivoting entry door that is many, many times heavier than any hinge door.
Large pivot door can be manufactured using available materials such as cement, metals (aluminum, cold rolled steel, copper, galvanized steel, hot rolled steel, stainless steel, steel diamond plate, etc…), natural or exotic woods (alder, bird’s eye maple, cedar, cypress, mahogany, olive, redwood, walnut, willow, etc… ), stone (granite, limestone, marble, sandstone, slate, etc…), just to name a few.
High precision maple
Straight warp-free maple
Heavy Pivot Doors
Though large pivot doors can span from floor to ceiling and the pivot door hardware can handle heavy weights, the challenge to overcome is the obvious one: The large size and heavy weight can create problems over time causing the need for routine ongoing maintenance dealing with issues that compromise either the pivot door or the structure itself.
Heavy pivot doors can cause undue stress on both the hardware and the structure, requiring maintenance on the pivot hardware, frame and possibly the structure under regular heavy use.
Light Pivot Doors
One way to optimize large pivot doors for weight is to use a strong lightweight substructure that will not compromise the structure of the door. SingCore large pivot door substrate is perfectly designed for large pivot doors sporting additional features besides creating a solid composite door that weighs a fraction of an otherwise solid door. How else could you make a lightweight 16 ft. tall white oak pivot door that can be guaranteed not to warp for 50 years? You can find 8 of these doors on the top floor of One World Trade Center, NY.
Modern pivot doors with patented Sing Core inside are strong (660 PSI, stronger than steel pound for pound) and the torsion box structure grids are packed with rigid insulation (for added R-value and sound deadening capabilities).
Using Sing Core inside your pivot door can transform any heavy pivot door into a lightweight pivot door.
Large Pivot Doors Warp
Warping large pivot doors are one of the chief problems associate with large pivot doors – or any large doors, for that matter – especially if the large pivot entry doors are made using natural woods, which are elegant when installed but tend to move according to variances in heat, moisture and other environmental conditions.
There’s really no way around the natural characteristics of wood grain to bend, warp, cup or twist – that is – until now…
Guaranteed Warp-free Large Pivot Doors
Only large modern pivot doors with professional SingCore inside can be guaranteed to remain structurally sound and warp-free for 50 years.
Wood Stave vs. Wood Ply
Wood stave doors can be very costly to make, especially if you’re looking for a lightweight high strength solution for a warp-free guarantee for 50 years. Using Sing Core inside your wood stave door featuring wood planks from 1/8-inch to 1/2-inch will create more potential for warp due to the nature of natural wood grain. This is the beauty of the more economical wood ply option for building your wood door. Wood ply is far less expensive and has alternating grain orientation which also helps to keep the door straight. Wood plywood is just like any other plywood except for its featuring a particular wood grain predominantly on the surface, and it offers far more strength and repairability over time than a less expensive wood veneer.
So, if you’re looking to attain similar visual results of a solid wood door at a fraction of the price you might consider having Sing Core inside your wood plywood door. Be certain to specify what type of natural wood plywood you want, if it is available, you can save thousands of dollars on your beautiful wood door. The most popular wood plywood features woods such as white oak plywood, maple plywood, oak plywood, mahogany plywood, walnut plywood, Douglas fir plywood, knotty pine plywood, and birch plywood just to name a few.

When you’re looking to divide a space into two or more spaces, you may want to have more of a true separation between the spaces, while not having to rely on permanent construction and insulation contractors and installation, especially if you’re looking for temporary walls or room partitions that are modular components.
Temporary walls and room partitions made with SingCore inside have extraordinary characteristics drawing interest from individuals in New York seeking our wooden room dividers as the stand out lightweight, high strength, modern room dividers from 3,000 miles away. You might be surprised to learn we send more wooden products to New York than any other single location in the USA.
Sing wooden room dividers are built to architectural specifications using any of all available wood species though even inexpensive standard torsion box plywood panels available via the Lowe’s Home Improvement Pro Desk are the value-added low cost alternative for the DIY wooden room dividers for the creative do it yourselfer on a budget.
Large Wooden Room Dividers
The biggest wood room dividers present the greatest number of challenges for architects, designers and contractors. Unfortunately, while large wooden panels are highly sought out for their beautiful appearance, performance-wise they can be problematic. Due to the nature of the natural wood, the panel will tend to warp, bend or twist and there is little you can do about it, unless it has SingCore inside.
Warp-free Wooden Room Dividers
SingCore is the solution for creating a wood panel room divider that can be guaranteed warp-free for 50 years, even in a wood panel standing 37 feet tall, if built and designed correctly with professional SingCore. Non-warping wooden room dividers are not the only solution provided when your room partitions have SingCore inside. You also get:
Insulated wooden room dividers, providing greater room separation, climate control and sound deadening qualities for added safety, security and privacy between rooms.
Lightweight wooden room dividers, that are less expensive and easier to transport, handle and install (while cutting down on potential injuries caused by working with heavy wooden room dividers).
High strength wooden room dividers, offering incredible strength – even from an inch-and-a-half thick panel room divider – to support the installation of a custom door without compromising the space dividers.
Any Type or Style of Wooden Room Dividers
Wood temporary walls are designed for a wide variety of styles, uses and configurations to meet or exceed the expectations of the best architects and designers in the United States.
Pivot Door Wooden Room Dividers
The most popular configuration for temporary walls are room partitions made using pivoting – or a combination of pivoting and sliding – door hardware.
Sliding Wooden Room Dividers
A fairly straightforward way to temporarily divide a space would be to place sliding doors to separate an otherwise wide open area. When you want the space open, simply slide open the sliding door room dividers and you’re in business.

Bedroom Dividers
You will find the insulation and sound dampening abilities of your Sing wooden room dividers will help you get a good night’s sleep in your cozy new bedroom, while enjoying the redesigned space, yielding a high quality of life with the addition of more bedrooms without the cost of expensive contractors.
Moving Wall
Your wooden room dividers could be configured to fully open providing full access to the entire space, when collapsed or folded, or dividing the space into multiple areas serving different functions as you see fit. Some installations include electronically articulating wall components using automatic door hardware with optional remote controls.
Pressure Walls
While some people are using our standard torsion box panels as components in quick and easy pressure walls, our friends in the greater New York area are feeling the crunch of building codes being enforced, especially in Manhattan. For these people, they are reaching out for using our insulated panels as backing for shelves, creating a
Bookcase Wall
Even though bookcase walls are trending now in New York, designers, architects and engineers have been specifying SingCore as the backing material for bookcase walls for increased insulation and room separations when in use as a room divider disguised as a bookcase. In fact, entire bookcases built of SingCore can be easily pivoted with a standard pivot door hinge and used as a temporary wall or secret door which could be opened when desired or necessary, not just as the bookcase wall nyc.

BIG Door
Many door manufacturers have problems with large doors (especially over 7 ft. tall) in that while they look magnificent upon installation, dealing with door warp on a regular basis is a constant maintenance cost associated with big doors.
This is where Sing Core door substrates shine because the substructure of the core itself is a combination of wood torsion box (using vertical grain matrix framing) filled with recycled rigid foam creates a lightweight, high strength solid substrate that will retain its original shape and structural integrity over time; higher precision and lasts longer than any other known door building material.
That’s why more and more, you are finding Sing Core™ inside some of the biggest aircraft hangar doors, large sliding barn doors, factory doors, large commercial doors, warehouse doors and large garage doors.
Non-warp Door
Sing Core™ is the only door core material that enables our door manufacturers to deliver doors that do not warp regardless of size or external materials in either interior and/or exterior doors, if they are designed by our Non-warp True Flat Specialists. Sing Non-warping door blanks are available in any type, style, shape, exterior skin and/or composite configuration.
Insulated Door
Insulated doors offer enhanced separation between two areas separated by an opening, doorway or egress point. Sing Core insulation starts at R3.5 per inch and goes up from there, based on architectural specifications. Insulated door are of primary interest to architects, designers and engineers seeking soundproof door, hurricane doors* or other weatherproof door where an insulated door is specified.
Security Doors
Sing Core is of primary importance in security doors of substantial size. Large security doors are difficult to manage normally due to weight; this problem can be solved with the Sing solution. A security door can be used in a variety of circumstances and applications including impact doors, and bulletproof doors.
Using Sing Core™ inside, impact resistant doors don’t have to be heavy weight, which causes unnecessary stress and strain on both the hardware and structure, while delivering all the security desired including increased privacy due to innate door insulation.
Specialty Doors
Sometimes a custom door manufacturer, millwork or door manufacturer faces a job that requires doors with unique attributes to accommodate a particular usage following installation.
Specialty doors may need particular characteristics to meet the requirements of the end user. Architects, designers and engineers can use Eco-friendly Sing Core™ inside to have greater control over:
Any size Any style Any performance Any exterior surface
Get the door that you want, when you want, how you want it to perform
Patented Sing Core is the most high precision door core material producing the highest performance doors in any type of door that are elegant and possess superior functionality.
The invention of insulated reinforced torsion box helps woodworkers solve the mystery of warping wood eliminating the problems of warp, bend, twist, cup, cracking and even rot.
Sing pre-built torsion box can be used to manufacture a lightweight true flat workstation. It would take hours – even days – of work to build an 8 inch thick torsion box assembly table that wouldn’t be as strong or straight as Sing torsion box panel.
Not just for torsion box table, the Sing Sandwich panel is a revolution of all paneling and can be reconfigured to any size, shape or dimension, even lightweight structural post and beam.
The cost is affordable due to mass production made in the USA, patented and shipped worldwide.
This is good news for the woodworker, contractor, millwork, cabinet and furniture manufacturers. Yes, you can even make lightweight, super-strong furniture components.
Lightweight Sliding Door or Pivot Door
Sing Core Panel Watertight Church Door
No more heavy sliding doors or pivot doors weighing in at 1,000 lbs. or more. Now you can make a sliding door or pivot door – even floor to ceiling oversized large door – that can be less than 20% the weight of a traditional sliding or pivot door, which means longer maintenance-free performance and less expensive hardware (and less door and hardware repair).
High Precision Accuracy and Solid, like a rock
Your lightweight door can now be solid (not like hollow or honeycomb core doors) insulated, sound deadening, stronger than steel (independently tested at the University of Washington at 660 PSI compared to other high-tech aerospace cores at 10 to 110 PSI). High end architectural millworks enjoy the highest precision building material within .006 inch tolerance.
50 Year True Flat Guarantee
Say, “Goodbye,” to your warped door. Only patented Sing Core enables door manufacturers to create doors that are true flat (far exceeding AWI standards for flatness) and are guaranteed to stay flat – not warp, bend, twist or cup – for a full fifty years.
Tiny House or Insulated Shed
Quickly and easily erect a tiny house or insulated shed using pre-built torsion box panels (aka Reinforced Structural Insulated Panel RSIP) and never worry about damage of loss due to mold or mildew.
Of the many features that are most appealing about using a large pivot door as your entry door is that they are not only visually attractive and inviting but the large size is impressive and commands respect, especially in terms of the first impression appeal.
This new generation of entry door can offer affordable elegance to the homeowner who desires to

Oversize Entrance Pivot Doors
“If we could build this giant warp-free wooden pivot entry door, we can build your door.” ~ Peter Sing
For thousands of years pivot doors have been the upscale preference of the most exotic high-end large oversize entrance doors relying heavily on the entry door hardware, specifically the pivot hinge, to manage the functionality of the pivot door.
Due to the size and weight of the conventional modern pivot door the heavy duty hinges and pivot door hardware could account for up to half the cost of the pivot door (e.g., a low end pivot door could cost $3,000, half the price will pay for the hardware due to the heavy weight), creating a high price point as well as being expensive to transport, handle and install.
Yet, the most demanding clients desire this elegant outswing exterior door to make an extreme visual impact for the primary access point of their structure (while bringing the outside in and the inside out by way of the architect’s modern design concept) regardless of price to command attention via first impression.
Pivot doors may be the most expensive designer doors but there’s no escaping the luxurious feel that they lend to designs by top architects who help to create the most leading edge structure designs by featuring the best exterior doors.
Since hardware is of huge importance in a pivot door’s design and implementation, there are many options to consider including offset pivot hinge, commercial door hinges, heavy duty door hinges and center pivot door hardware in your pivoting door system.
High precision—-Sing Core tolerance within .+ or – .007 inch
High strength—Sing Core door panel could design reach beyond 700 psi vs other lightweight core average 10 to 50 psi.
Less hardware and install cost.
Safe for kids to operate.
Warp-free and structure guarantee for 50 years
The best large door guarantee in the world; make sure to ask the door supplier for warranty if you have a large door to be built.
You do not want to have a problem if investing in tens of thousands of dollars in your high end door. Patented and patent-pending Sing Core door panels will make Sing Core clients less worried about door warping or lack of structure strength over time.

Steel Pivot Doors
Many pivot doors feature metal structures and framed composites and more popular for exclusive high security environments, commercial steel entry doors and even residential steel entry doors.
How to Build an Exterior Door
Many considerations must go into the design, plan, building and installing a pivot door.
1. The Core Material The core material that makes up the heart of your pivot door determines so much. Based on your choice of material you will determine your pivoting door’s:
Weight
Strength
Insulation
Precision
Performance
Maintenance
2. The Frame
Will your pivot door be a solid one-piece material construction, or will it be framed or unframed?
Many options about for the substance of your pivot door, first – the most heavy and likely the most unstable – is solid construction, then framing. Framing your pivot door can be with wood or metal, like steel or extruded aluminum. Wood will move framing with metals, like a conventional steel door, may not meet high performance specifications due to welding creating imperfections in the metals.
3. The Entry Door Styles
What will the general appearance of your door be? What exterior surface material, skin (see material options) or design will make your pivot front door stand out to make that impactful visual impression?
4. Hardware
What hardware will be required (price is usually influenced by style of pivot and finished weight of door) for optimal performance of your pivot door?
5. Installation
Who will install your pivot door and will any special handling/equipment be required for installation?
Can the Affordable Pivot Door Replace Contemporary Entrance Doors?
Until now, pivot doors have generally been too expensive for the average homeowner to consider, but one pivot door core material is changing all that. Sing Core manufactures an Eco-friendly pivot door core material used by the most high-end architects, designers, door manufacturers, millworks and contractors for building the best pivot doors in the world.
What constitutes the best pivot door in the world? One that is:
1. Eco-friendly (sustainable, true green)
Sing Core panels are constructed with natural wood fiber vertical grain torsion box filled with recycled rigid foam adhered between stress skins using formaldehyde-free glue for a solid substrate.
2. Lightweight
Sing Core panels weigh a fraction of the weight of other solid structural building materials.
3. High strength
Sing Core panels were independently tested by the University of Washington at 660 PSI for super-strength (compared to 10 to 110 PSI of other honeycomb cores used in the aerospace industry).
4. Insulated
Sing Core panels are packed with insulation rated at R 3.5 to R 6.5 (depending on foam selection) and feature sound deadening qualities for security and privacy.
5. High Precision
Only Sing Core panels can be created to be true flat, within .006 inch tolerance with little or no deflection.
6. Versatile
Sing Core panels can feature any surface material (skin), like any wood species, aluminum, ceramic, concrete, fiberglass (FRP), HPL, Kevlar, LVL, MDF, stainless steel, stone or any other flat building material, may host any glass lite openings in any configuration and can be embellished to have the appearance of any style door imaginable.
7. Guaranteed not to fail
Only Sing Core’s professional pivot doors can be guaranteed true flat and to stay flat and not to fail for 50 years. (See free consultation).
Only by using patented Sing Core can any pivot door achieve such results.

How Can I Get a Sing Core Pivot Door?
There are many ways that you can make your pivot door dreams come true.
1 Architect
Architects have access to Sing Core technology and are specifying Sing Core in their pivot door designs – especially if they are large pivot doors – that can be manufactured by their favorite millworks.
2 Millworks
Most one-of-a-kind custom pivot doors are created by revered craftspeople and woodworkers who create hand crafted pivot doors for exclusive clientele.
3 Door Companies
Any door company can use Sing Core panel as the substrate for your pivot door. Though many do not feature the Sing Core pivot door as a standards catalog item, in most cases you can special order your pivot door with Sing Core technology.
4 Contractor
Sing Core pivot doors panels are sold without hardware installed and unfinished. Our door panels are manufactured for mill works to install hardware and finish. We do not recommend shipping Sing Core door panels the job site for installing hardware and finishing. This is not the best way to treat a high end door such as a large pivot door made with Sing Core. We highly recommend the GC work with millwork professionals to finish at their facility (except some special restrictions).
We believe each professional has it’s own specialized knowledge just like we do not expect an architect to install the door, instead using a highly trained GC.
Since the weight of your Sing Core pivot door will be a fraction the weight of a solid (or framed) pivot door you can save cash that would have to be invested in heavy duty pivot door hardware that could account for half the cost of any other pivot door.
Plus you save on transportation and installation costs, just like our clients (see clients list) and enjoy maintenance-free high performance of your pivot door.
Standard Sing Core Cold Rolled Steel Pivot Door Blanks are manufactured with patented Sing Core material as the base interior substrate of the 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. The core material is framed by 1.25-inch wood stiles and rails for finishing strength and attaching hardware. The torsion box is completed by adhering 20 gauge cold rolled steel as exterior material (skin) according to your specifications. The man door opening is cut out to architectural specifications.
