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.

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.

Sing Core solves the issues with warping and eliminates the mystery of the warping door. By integrating Sing Core into your door’s composition you can have an elegant, maintenance-free long-lasting door that will not warp, bend, twist or fail regardless of size or application.

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.

Add MDF skin or plywood for paint grade and wood grain.

High Precision Doors

Foam-Panel-Interior-Structural-Torsion-Box-Sing-Core-RevealedSing High Precision Doors are a marked improvement in door development, design and implementation thanks to a newly invented Eco-friendly core material that is lightweight, insulated and stronger than steel pound for pound.

This new technology is revolutionizing the door industry especially in regards to large oversize doors. Architects, designers, mill works and door manufacturers all experience problems with doors that are larger than normal size.

Large doors present a variety of challenges in areas, like:

  1. choice of available materials
  2. lightweight doors are weak and tend to fail
  3. Copper-Doorheavy doors strain hardware and structure
  4. increased regular maintenance
  5. failure due to warping

Sing High Precision Doors solve all these issues with an Eco-friendly insulated solution.

How high precision are Sing High Precision Doors?

Sing High Precision doors are created with so much accuracy that the original door slabs are perfectly flat within .0006 inch accuracy.

After applying your desired composite materials and/or skin, your high precision door can be laser CNC machined for a perfectly flat surface, limited only by the accuracy of your CNC machine shop capabilities.

The Large Challenge

Certainly, you could use laser CNC cutting and engraving to machine nearly any door made of almost any commonly used door material for a flat result. The challenge comes from standing the door upright and expecting a degree of effective usefulness over time.

lightweight high strength engineered plywood for making large sliding doors aluminumWhy Large Doors Fail

The effects of gravity, varying degrees of moisture and/or atmospheric change, and the natural limitations of the characteristics of the building materials that comprise the door all contribute to its failure. This causes dissatisfaction for the end user, who has invested a great deal of expense in the design, manufacture and installation of this specialty large door.

Door warping is the number one problem for oversized doors that are otherwise enjoyed by the most discriminating end users.

The Disappointment

No one wants to spend that kind of money on a door that is going to warp, bend, twist, delaminate or compromise the structure or hardware with normal recommended use.

Now, here’s the exciting part…

Sing High Precision Doors can be guaranteed not to warp, bend twist or otherwise fail for 50 years!

large-lightweight-high-strength-garage-carriage-doorsImagine having a large door that can be installed that will not pave the way for repeated service calls over the life of the door.
