Challenges of Oversized Large Doors

When considering a door larger than normal (that might be referred to as an enormous door) many challenges arise for the architects, designers, millworks, builders and installers. Some of the most common problems associated with big doors include:

Warped Door

If the door is taller than seven feet tall and wider than four feet then the door will warp. Warped doors are a common occurrence associated with large doors. This can be annoying for the end user due to the constant maintenance calls required for dealing with the warping door (though it is good for the door service business).

Big Doors Are Heavy

If a door is large you are going to have a lot of weight to deal with. This excess weight causes many issues associated with the building, transporting, installing and maintenance of the door from inception and throughout the service life of the door.

Big Doors are Expensive

Heavy building materials require more time, manpower, resources and equipment to make the door and the result is a big door that is overweight. Heavy doors are expensive to deal with; expensive to crate, ship/transport, offload, finish, store and install.

Overweight doors require more expensive hardware, and the added stress on the frame and the structure requires more regular maintenance over time.

Modular = Newest Development in Large Doors

Sing Core technology has advanced to a completely new level by introducing the modular large doors for combating even more challenges associated with large doors; by creating doors that are shipped as individual components and assembled on-site.

These extremely large doors would cost thousands of dollars to ship (if not impossible due to their large size) but if made in modular components, the large door can be shipped flat-packed and sent by traditional shipping methods reducing shipping costs tremendously. And, the resulting big door can still be guaranteed not to fail!

True Flat Technology Goes Modular

Long known for the largest non-warping doors, Sing Core takes modular huge doors to the next level while still making their 50 year non-warp guarantee. The components are shipped separately and assembled on-site for the biggest doors that can still be fully insulated, operable and manageable without the heavy maintenance required for other big doors. Many connection methods are available for these large door projects including making components using our T Slot Panels as individual components that can be perfectly aligned on site.

Free Large Door Consultation

Of course, building such a door up to 50 feet wide is an art in itself. Each door is designed for its intended purpose. Some of the questions our specialized doors creators ask might include: Will your large door be underwater, in outer space, exposed to extreme weather, need to be bullet-proof, waterproof or soundproof? Also, “What kind of door will you need?” A large sliding door, pivot door, French door or other type of door, etc…

Commercial trade professionals are encouraged to contact us for a Free Large Door Consultation, so that you, your clients and the world at large can know what it is like to own an non-warping large door of any size.

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.

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.
