Wooden sliding doors are the most sought out sliding doors in the marketplace today. Increasingly, among contemporary architecture design the latest designs feature not only wooden sliding doors, but wooden sliding doors that are larger in size. Even though these large wooden sliding doors are highly sought after, the nature of the natural wood in wooden sliding doors does present some challenges.
Wooden Sliding Door Problems
Wood is Beautiful but Unstable
While we all appreciate the natural beauty of wood, the fact remains that this material comes from a living tree and naturally adorned with grain that is unique to each variety of tree giving it the elegant design feature of natural wood grain. The nature of the wood grain when we are so drawn to is also the most problematic feature when trying to create a sliding door which can remain straight enough to function properly. Natural wood grain, while it appears to be elegant in every way, moves as if the tree were still alive. In the sliding door industry sliding door manufacturers and those servicing sliding door accounts, there are specific words used to describe the conditions of wooden sliding doors when they fail, such as warp, bend, twist and cup.
Allowable Wooden Sliding Door Warp
Due to the nature of wood to warp, the AWI standard allowable warp for a door up to seven feet tall is a quarter of an inch of warp. ¼ inch warp in a 7 ft. door is considered a straight door. For wooden sliding doors over 7 ft. there is no limit to acceptable warp due to the nature of natural wood and its tendency to move subject to changes in the environmental conditions on either side of the door. The most problematic wooden sliding doors are exterior sliding doors because one side faces indoors, while the other side faces the elements. Interior doors have fewer problems with sliding door warp, but if they are over 7 ft. tall, will continue to present problems with sliding door warp.
Wooden Sliding Doors Are Heavy in Weight
The weight of natural wood is another issue to take into consideration when entertaining the idea of including a large wooden sliding door in your project’s design. Heavy wooden sliding doors will create added expenses very early on in the inclusion process, such as the added cost of shipping and handling. Moving the door from point A to point B will incur expenses based on the wooden sliding door’s weight. After the heavy sliding door arrives on the job site, installers must manhandle the door, and use heavy equipment to help maneuver the door on site. Additionally, a heavy wooden sliding door will require heavy duty sliding door hardware, which may cost many times more than the wooden sliding door itself.
Wooden Sliding Doors Have No Insulation
Large wood sliding doors vibrate, like a speaker, transferring sound from one side of the door to the other, which may not be a problem if your location is in the remote wilderness. Besides sound transfer, loss of energy is significant as wood is unable to maintain climate separation from one side of the door from the other, which is also many times more problematic for exterior sliding doors or doors separating two spaces that may have separate activities occurring on either side (such as office, meeting or recreational spaces).

Patented Sing Core solid wood stave sliding door blanks feature the newest technology in the door industry for composite sliding doors yielding the only eco-friendly, lightweight, fully insulated, high-strength sliding doors with wood blanks of any size (up to 40 ft.) that can be guaranteed true flat and to stay flat for 50 years.
Large sliding door versus regular-size sliding door challenge (i.e., over 4 feet wide and over 8 feet in length):
Large sliding doors are heavy, dimensionally unstable, require more strength due to the heavy weight, and are a challenge to manufacture, ship and install. High-end jobs require precision and true flatness to please the customer. A homeowner’s architect, general contractor and mill worker must solve the problem of warped sliding doors. The solution to the challenge is to use patented professional Sing door blanks to make your sliding doors.
Sing Core wood stave door blanks help door manufacturers to create the only solid wood sliding doors that will not warp, bend, twist or cup following installation. This means no more continuous service calls for maintenance of big sliding doors that cannot possibly stay straight due to the limitations of solid wood – or any other sliding door core – that is subject to failure. Sing sliding door blanks have a patented honeycomb/torsion box interior which gives lightweight yet unsurpassed strength (pound-per-pound stronger than steel) and stability to any door, and allows Sing Core to provide a 50-year guarantee
Sing sliding door blanks make amazing designer doors in any style. With Sing sliding door core, fragile sliding doors such as French doors are made lightweight yet strong, not warping or breaking hinges, which will last for many decades.
Sing sliding door blanks make sturdy exterior doors in any style. With Sing sliding door core, exterior sliding doors are lightweight and strong, even when oversized. Our professional wooden sliding doors are guaranteed to stay true flat and not warp or twist for 50 years
The problem is that all sliding door core materials are either not high precision, too heavy or will move when exposed to moisture, humidity or change in temperature resulting in sliding door failure.
Heavy solid metal or steel will not warp, bend or twist, but is not high precision due to welding (sing core tolerance is + or – .006 inch!) and is often impractical due to the overweight issues causing excess strain on both the hardware and structure, causing continued maintenance issues. The solution is our patented lightweight yet strong Sing core wooden sliding door technology.
Finishing a wooden sliding door blank:
There are two types of finish for door blanks: paint grade and wood grain. Paint grade includes such finishes as domestic and marine plywood, etc. Wood grain finish includes such finish as solid wood stave and/or thin veneer.
Why Use Solid Wood Instead of Veneer?
Never settle for substandard veneer sliding doors again. Door engineers prefer to use inexpensive veneer as opposed to real solid wood facings because veneer is thought to be less likely to warp, bend or twist. But thanks to the super-strength of patented Sing Core technology, you can use solid wood stave and wood blanks with confidence knowing that your wooden sliding door can be guaranteed true flat and will stay flat.
How can a solid wood-faced sliding door stay true flat? As every woodworker knows, when using a solid wood surface, the grain will move according to moisture or temperature change causing the door to fail. When using our patented Sing Core as a substrate you can safely use solid wood because the patented solid torsion box composite material is continually keeping the wood grain straight and true. Whereas wood stave has more wood fiber giving it more of a chance to warp than thin veneer due to the unbalance of the both side of the door moisture contents, patented Sing technology solves this problem by combining patent pending stiffening materials throughout our Sing core. This warp-free Sing wooden sliding door technology eliminates the troublesome movement of the sliding door blank — warping is no longer a concern when wood stave is combined with reinforced patented Sing core.
In addition, solid wood is easy to work with, install (no need to hot press), repair and remodel. That’s why professionals trust Sing Core’s years of expertise in helping to design the only wood stave sliding doors (that look just like solid wood sliding doors) that can stay straight and true for many decades while respectfully honoring the beauty and elegance of solid wood, which far outlasts easily-damaged veneers, yet can be sanded and repaired if necessary.
