Wide Doors for Hinge or Pivot Door Hardware

Oversized large paint grade Sing pivot door panelExclusive to multimillion dollar spec homes, the standard extra wide exterior doors are pivot doors to accommodate the unique challenges of wide doors.

The Problem

Wide doors will warp, not just top to bottom but side to side which compromises the seal and creates a problem for latching the door. Wide doors are problematic due to warping requiring regular maintenance to adjust the wide door accordingly.

The Solution

The Sing non-warping Professional Pivot Door Panels are the solution because if the door does not warp, you’ve solved the problem with the failure of wide doors altogether, and can be guaranteed to remain non-warp for 50 years. Even $10,000 wide doors cannot be guaranteed not to warp; even for one day.

No-fail Pivot Doors

The nature of pivot doors – especially oversized large pivot doors – leads to increased maintenance costs due to warping. When you think of pivot doors warping, you first thought is to think that the door warps along the longest length from top to bottom; it is even more common side to side. Any warp will not only compromise the seal of the door but it will also prevent the door from securing and latching properly. Only Sing pivot doors can be guaranteed not to fail.

Advantages of Professional Sing Pivot Door Panels

ProfessionalSing pivot door panels are the only Eco-friendly lightweight, high strength pivot door blanks that can be guaranteed not to warp or structurally fail for 50 years.

Eco-friendly

Made in the USA professional Sing pivot door panels are manufactured using less natural resources (natural wood), recycled rigid foam and formaldehyde-free adhesives. The manufacturing process uses less energy to produce that creates little or no waste.

Lightweight Hardware

The lightweight nature of a professional Sing pivot door blank means saving thousands of dollars in labor, transportation and installation as well as the heavy duty hardware that would be necessary for a heavier door. For instance, a standard 8 ft. door would weigh-in at 720 lbs. compared to lightweight Sing Core’s 120 lbs. reducing the cost of the hardware significantly. In fact, Sing pivot doors are so light, you could use standard hinges, if you wanted to, without fail.

Sandwich Panel Box will not Rot

This Sing honeycomb plywood garbage bin will not warp, bend, twist or rot!

Sing core plywood panels will not warp, bend, twist or rot.  They stay true flat, even when exposed to the elements.  The revolutionary patented Sing core technology has solved the warping nightmare.  Thus, plywood boxes made with Sing plywood sandwich panels are true flat (non-warping), will stay true flat and can be guaranteed true flat for 50 years.  It is like Sing panels have true-flat memory!

Our patented Sing panel core is a honeycomb/torsion box foam grid wherein the wood grain is perpendicular to the skin and held together with our patented formaldehyde-free glue.  Our patented Sing cores are 90 percent air, which does not move, and are supported by the strongest structure possible.  Because there is no movement in the core, the surface material (“skin”) will not delaminate and leak.  Therefore, plywood structures made with Sing plywood panels make the best outside structures.

How to Fix a Warped Door

Many people struggle with how to fix a warped door. Nothing is more frustrating than spending your hard-earned money on a nice door, only to have it warp, bend, twist or cup not long after installation.

This problem is magnified exponentially especially if the door is a large oversized door. Some of these high-end large doors can cost tens of thousands of dollars only to discover failure due to warp when the season changes. This can mean job security for door repair services, millworks and contractors serving the account, but can lead to dissatisfaction and frustration for the client.

Patented Sing Core

Patented Sing Core

Dealing with how to fix warped wood doors is considered standard maintenance for high-end applications; that was until the invention of patented Sing Core. Only large oversized wood doors made of Sing Core can be guaranteed true flat – and to stay flat – for 50 years. See: No More warped Doors.

Demystifying Door Warping

There is no longer any need to be frightened of doors warping, due to our extensive experience in providing doors (even huge, enormous doors) that are guaranteed not to warp for 50 years to the most proficient building designers, contractors, mill works and high end door manufacturers.

The biggest problem for doors is warping (especially in large doors) used n high-end home building projects and commercial projects when building sliding doors, pivot doors and big interior doors.

Most door manufacturers and millworks avoid building doors over 8 feet tall or offer a very limited one year warranty with many exclusions/restrictions to prevent exposure to damages due to warping. Click here to see

When you buy your door, and even following installation, it may or may not be flat. Most doors begin to shift and move following manufacture. By the time your door arrives at the job site, it may already be warped or beginning to experience separation between the exterior surfaces and the core material.

Certainly after years of regular use (paper core, foam core) will warp and/or delaminate.

lightweight high strength engineered plywood for making large sliding doors aluminumNo matter what kind of standard core a door is made from, whether paper core, foam core, SLC (Stave lumber core), particleboard, SCLS (Structure composite lumber), LVL (Laminated veneer), mineral core, MDF, cardboard, etc… warping is inevitable. Even a solid wood door will warp. A sliding or pivot door will have unbearable warp at only ¼ inch due to the reference next to a straight wall or door jam. This warping is even worse in a door over 8 feet because of the strength of the movement. So far, the best solutions have been to only make 7-foot high doors, or to make excuses (i.e., no or very limited warrantees) for doors over 8 feet, or to use gaskets to hide the minor warping, but these are temporary solutions that require costly maintenance and replacement and tarnish the reputations of the building trade professionals involved in the projects. As such, most doors usually do not have warranty protection against the inevitable warping. Even with SCLC (Structure composite lumber core) and LVL (Laminated veneer), commonly used in high end large door will not remain true flat due to the wood fiber constantly moving.

Finally, Sing Core provides a guaranteed solution to the challenges of warped doors and it is the only affordable lightweight high strength solution that can provide 50 years of high performance, remaining straight and true without fail. Plus, Sing Core offers insulation qualities that cannot be found in other strong (heavy) building materials. Only this unique patented torsion box/rigid foam composite can offer the superior strength – bridging long spans, or towering heights – while insulating and providing sound deadening benefits.

Sing Core helps door manufacturers and mill workers build doors which satisfy even the most challenging high-end door market. (Click here to see our client list.) Doors made with our patented Sing core panels are true flat and may be guaranteed to stay true flat for 50 years. In addition, our patented Sing Panels (door blanks) are:

1. Dimensionally stable with a high precision tolerance of +/- .006 inch. This is laser precision which produces the smoothest and most true-flat panels.
2. Fully insulated for temperature control and sound-deadening qualities and which are 3 to 5 times more insulated than solid wood-based door cores.
3. Lightweight so that even a 4 inch thick door will weigh only 2 to 3 pounds per square foot. An average wood-core weighs 8 to 10 times more than our patented Sing core.
4. High strength which has been verified by the University of Washington at above 660 PSI, making our Sing panels pound-for-pound stronger than steel. (You could drive a 12,000-pound forklift over them without crushing them!)
5. Water-resistance/waterproof doors made of patented Sing core panels can be completely exposed to the weather without warping. (Click here to see our exterior door gallery.)
6. Eco-friendly and non-toxic structure glue for bonding skins and Sing core.

Aluminum skin only for paint grade or wood stave.
