The new American pivot door is causing a stir across the USA among designers and architects opening an entirely new range of possibilities for the modern pivot door in contrast to pivot doors designed by and enjoyed by our forefathers.

The new pivot door making its way into the mainstream of contemporary architecture design is decidedly different from its predecessors in that this new generation of pivot door is Eco-friendly, lightweight, high strength, fully insulated, and can be guaranteed to remain warp-free for 50 years, regardless of size, resulting in the most sustainable pivot door in the industry.

This empowers modern designers and contemporary architects to design a pivot door of enormous proportion, up to 50 feet, which would otherwise be highly problematic in terms of design, construction, shipping, transport, maneuvering on site, installation, with increased highly-skilled labor and heavy equipment costs.

Let’s examine the characteristics of this pivot door one by one:

Pivot Door: Lightweight

Pivot doors can be made lightweight by sacrificing the core of the pivot door altogether. In the past pivot door manufacturers would compromise the inside of the pivot door by leaving it hollow or by using a lightweight core alternative, such as paper core, carboard core, or some other type of honeycomb core. Such a lightweight pivot door is prone to fail.

The latest innovation in pivot door technology incorporates a solid composite core which is based on a reinforced vertical grain torsion box core which is high precision (+/- .006 in.) and weighs a fraction of the weight of other solid pivot door core options.

Pivot Door: High Strength

Strength in the architecture of a pivot door is of primary interest because it determines the usability and functionality of a pivot door’s performance over time. If a pivot door is not strong (which pivot door engineers usually equate a lightweight pivot door with weakness), it will be prone to failure due to warp, and may bend, cup, twist or otherwise fail over time.

Patented Sing Core imbues a large pivot door with enormous strength (over 660 PSI) which is stronger than steel pound-for-pound. Only by using inventor Peter Sing’s patented vertical grain reinforced torsion box core is such a feat possible at such light weights.

Pivot Door: Fully Insulated

Insulation is of a concern amongst custom pivot door creators in terms of separation, security, and preservation of the space on either side of the door. Since the most effective use of a pivot door is as a main entrance door (especially if it is a large pivot door), insulation is a desirable component for keeping the interior space heated or cooled, and sound-deadening pivot doors can be very heavy indeed.

If your pivot door has Sing Core inside, you have a fully insulated solid composite core which provides both sound-deadening and climate control capabilities. This is why increasingly you find Sing Core specified in both refrigeration and sound proof pivot door specifications.

Pivot Door: Warp-free

Among the problems associated with large, oversized pivot doors, is pivot door warp. In most high-end pivot door applications warp is a problem due to the mass of the material. Most problematic are the challenges when building a pivot door of wood. A wooden pivot door will be compromised and fail when the grain on one side of the door is exposed to differing environmental conditions on the other side of the door.

Inventor Peter Sing can help to design the perfect pivot door substrate using his patented and patent-pending door technologies to create an anti-warping composite core that can counteract the tendency for wooden pivot doors to warp, thus resulting in the only door in the world which can possess a

Pivot Door: 50-year Warp-free Guarantee

Guarantee not to warp, ben, twist, or otherwise fail – including a full structure warranty – for 50 years.

No other pivot door company can do it, unless the door has Sing Core inside.

Sing’s patented pivot door core material is only available to the most highly reputable pivot door companies, millworks, and custom pivot door manufacturers around the world.
