High-end Veneer Doors

Sing Core specializes in increasing the performance, durability, and customer satisfaction in high-end veneer work in custom veneer doors of any size which can be guaranteed to remain warp-free for 50 years, including full structure warranty. No other method of manufacturing a large high-performance veneer door can achieve these results.

It all starts deep within the structure of any veneer door with Sing Core inside. Sing Core is the patented brainchild of inventor Peter Sing who conceived of the structure core which revolutionized the way doors were made.

Sing’s invention is basically a vertical grain torsion box core with small grid structure where the grid voids, which are usually left open in traditional torsion box, are filled with rigid foam insulation.

This composite base material is pressed between to stress skins to create Sing’s lightweight high strength high-end veneer door core.

The biggest and best door companies, millworks, and custom door manufacturers love it, and you will find them using Sing Core inside all their high-end custom large veneer doors. And that’s why you’ll find them at the top of the tallest building in the United States of America, World Trade Center 1‘s Freedom Tower.

Telegraphing and Crossbanding

The most environmentally conscious way to create a veneer door is with a thin veneer material, such as 0.020-inch veneer. The only problem with this thin veneer is telegraphing.

It is normal to crossband veneer, which basically doubles the price of the veneer, to prevent telegraphing.

Not necessary with Sing’s super-smooth veneer door blanks. He uses his patented veneer door technology to create an extremely smooth surface to lay veneer on flawlessly by using a thin later of MDF to accommodate the lamination of a thin veneer.

Problem solved.

Large Oversized Veneer Doors

When architects spec an architectural veneer door, if it is a very large door (anything over 8 ft tall or 4 ft wide) they are far better off going with a thin wood stave surface. Wood stave consists of wood planks cut into thicknesses of 1/8 to 1/4 -inch thickness. Then this solid wood is applied to Sing’s door blanks.

Veneer is normally limited in available lengths, whereas planks of specific wood species are generally available in longer lengths. This can accommodate the long length necessary for a vertical grain veneer door design.

Plus, if it’s done right, your high-precision large wood stave door with Sing’s core inside looks just like a solid wood door. Only it weighs far less than any other solid core door, and can be guaranteed not to warp, bend, twist, cup, or otherwise fail for 50 years.

And no other door can come backed with such an impressive guarantee.

Even though Sing’s doors are desired by nearly everyone, to have such a door may be cost-prohibitive for most. It is more common to find high-end veneer doors with Sing Core inside in the most expensive homes in the USA. You may find them used in scientific research, and anywhere in the world, from beneath the sea (US Navy) to outer space (NASA) and anywhere in between.

Once you’ve experienced a high-end veneer door of such magnitude, you will agree with the professionals who insist on using Sing’s patented solutions, that,

“It’s the only way to do it.”

Sing Core is the only way to build a big veneer door that can be guaranteed for 50 years. The only way.

How to Make the Best High-end Veneer Doors

If you approach the most prestigious millworks in the world and ask them how to make the best high-end veneer doors in the world, you are likely to receive a response which references Peter Sing’s patented and patent-pending veneer door technologies and his Master Quality Door Veneer Surfaces.

Wood veneer doors are growing in popularity due to the design features which are available in matching grain orientation on the faces of the door. The most popular orientation is called “book match” which orients leaves of veneer opened alongside each other in alternating pairs, like opening a book, where the left leaf mirrors the leaf on the right.

Book matched veneer doors are followed by “slip match” veneer doors, where the grain orientation of the leaves all face the same direction alongside one another.

There are other types of veneer matching which includes “end match,” where veneer leaves are mirrored end to end, “reverse slip match” which alternates veneer strips flipped end to end, which greatly reduces any mirroring effect, producing a more natural result. “Random match,” which shuffles all the pieces and creates a more unique succession of veneers placed side by side.

Then, there is “blueprint” which is sequential veneer from a single source to cover an entire area. Complete rooms are the most impressive when they are blueprint veneered. Some jobs include matching blueprint door skins as well. Proceed with caution, making sure there is enough source material to complete the job, and there is no room for mistakes.

Beyond these veneer matching options; special matches can be made to create a desired artistic result for high-end architectural veneer doors.

These matching capabilities are unique to veneer because veneer is sliced so thin that there is grain duplication which can be matched or mismatched according to an artist’s or designer’s vision.

Veneer Door Problems

When tasked with bringing a veneer door to life, the production team can run into problems associated with building veneer door as specified while achieving high precision high-end results which the most demanding exclusive door clients find highly desired and valuable.

1. Perfectly Smooth Veneer Problem

High end veneer doors need to be perfectly smooth. Because the veneer skins are so thin, you will notice “telegraphing” on the skin surface. The term telegraphing refers to essentially the bleeding-through of any of the under-laying surface, which will impact the viewable surface area of the veneer.

If you apply veneer directly to a plywood surface, for instance, in the right light, you will be able to see the terrain of the plywood through the thin veneer.

In large doors, it can be extremely difficult to find a large enough piece of smooth underlayment material, so if there are seams in the material under the veneer, this would also telegraph through to the surface.

One way to achieve a perfectly smooth surface is to use LVL (which is commonly used by most standard door manufacturers underneath wood veneers) or MDF which are smooth but heavy, and both are limited in size availability. So, if your high-end veneer door is oversized (over 4 x 8 or 5 x 10) it can be impossible to find a single seamless product.

2. High Precision Veneer Problem

High precision is a moving target when approaching the design and production of a veneer door. The surface material may be elegantly fashioned, but if the product which the door is made out of has a tendency to move, then you could be in trouble when the door warps, causing inconvenience and potentially expensive regular maintenance and repairs in the field over time.

Due to the nature of standard door building technologies, the AIA allows for ¼” variances for a 7 ft. span of a door. Door manufacturers and door hardware manufacturers allow for these variances in mounting and hardware. If a door exceeds movement over ¼” along any 7 ft. span, the result is a warped door, which can easily be compromised or fail altogether.

How to Build the Perfect 16 ft. x 3 ft. High Precision Warp-free White Oak Door

You start with patented and patent-pending Sing Core inside sandwiched between American-made A/B plywood with solid oak around all four edges.

After pressing, trim the edges, then add another 1” x 2.25” solid oak to the edges. Sand it to perfection then hot-press 16th-inch white oak veneer, then all you can see is solid white oak. Beautiful.

The result is a perfectly flat lightweight white oak door that is stronger than steel pound-for-pound, weighing in at a mere 220 lbs.
