50-year Warp-free Guarantee
You have never heard of such a guarantee on big doors (especially big wood doors) before because before the invention of Sing Core such a thing was impossible.
And our best clients? They say,
“There is no other way to do it.”

What do they trust Sing Core for?
High strength garage door, finished by Artistic Doors and Windows. When building a specialty door like this, you want it to last.
The Best Solid Wood Stave Large Doors
Solid wood stave presents the biggest problem for large doors due to the natural tendency for a thick piece of wood to respond to its environment by moving. This is not too bad for normal-sized doors, but once you get over 8 ft. tall, you start finding trouble everywhere you look, unless your solid wood stave surfaced door has patented Sing Core inside. Then, it will not move.
Some wood species are more prone to warp than others, so Sing’s True Flat Team goes to work integrating the interior design of the wood stave door with additional anti-warp tech inside the door to compensate for stronger wood grains.
Other large wood door manufacturers offer a one year non-warp warranty, while patented Sing Core comes backed with a full 50 year non-warp and structure warranty.
The Best Large Veneer Doors
When it comes to thin veneers (which can be paper-thin) we have trusted artisans do this work, because we believe that this level of expertise requires that extra finesse to achieve the desired results. Our doing the veneer-piece is actually quite rare because the bulk of our veneer door responsibilities is supplying the many millworks and door companies with the warp-free high precision core for them to apply their own veneers.
This type of work is so sensitive that we only trust the people who are highly specialized in veneering (and that is all they do), so they are quite expensive. We do not want to compete with our own clients. We only use the best veneer craftsmen to work on our clients’ doors. They source the best veneers available in the USA via their suppliers.
If you have a millwork near you that specializes in hot press veneer, we can work with them, if you trust them. Most of our veneer substrates are delivered to millworks who are qualified to to this type of work. Let the experts do the high end jobs.

The Best Large MDF Doors
For so long, MDF has been a difficult material to work with because it is so heavy and not very stable, but engineers and high-tech artisans love it because it is so supremely smooth. This attracts and commands the attention of the most creative artisans in search of the perfect large door canvas. Can be used for 6 panel door, or any other kind of door including French doors with glass cutouts. Sing’s core makes these doors much more manageable by greatly reducing the weight, while increasing dimensional stability, even on enormous doors, and these take advantage of Sing Core’s +/- .006 tolerances.

Even 6 panel doors at a low cost if in large quantities.

This guarantee was unheard of in the industry, especially for large doors which traditionally were featured as exclusions from standard warranties because inherently they would fail and require service not long after installation (eliminated even from the most rudimentary 30- to 90-day standard warranty).
In fact, until recently, the largest door companies have turned away large door business in recent years, because, according to them,
“It’s just not worth the hassle.”
And they encourage the developers and contractors to find a high-end millwork or custom door maker to build the large doors in the project. These highly skilled craftspeople did the best they could, until they discovered Sing’s patented lightweight high-strength patented core.
Then, all of a sudden, they were building the most beautiful largest doors with incredible ease and without the heavy burden of having to service the fail-free large doors. In fact, they proclaim,
“There’s just no other way to do it.”
Now everyone, even the large door companies, are getting back into the oversized door game again, because they trust Sing Core to have their back when they most need it, from the inside out.
Make sure your next high-end door has Sing Core inside.
