SingCore is an extraordinary building material that left to itself is not much more glamorous than any other engineered plywood, even though nothing can compare to SingCore’s unparalleled light weight and strength. Yet, in the hands of a skilled millwork, their specialized craftsmanship is what makes Eco-friendly SingCore shine with the beauty and elegance SingCore products are known for.

Millworks face many challenges when bringing the architect’s vision to life. In some cases, the limitation of available building material can render a potential job impractical or even impossible.

Large non warp exterior sliding doors guaranteed for 50 years lightweight high strengthFor instance, a particular project might include a large wooden door. If the large wood door is an exterior door over seven feet tall or over four feet wide (as is the case for most modern pivot entry doors) millworks and custom door manufacturers will simply pass on the large door portion of the job, forfeit the entire job altogether based on the oversized exterior door, or if they do take the job may agree to build the large door according to the architectural specifications but will not offer a warranty on the performance of the big door.

Large exterior doors, especially large wood doors, are a problem because millworks and door manufacturers know the doors will fail due to warping. It’s nothing personal; it’s just the nature of the beast being the wood grain itself which tends to move according to changes in temperature, moisture or other environmental conditions.


Building warp-free wood doors of any size with SingCorePatented SingCore when engineered by the warp-free team can prevent any large door from failing over time. Millworks are confident they can provide a solution for any project including large doors of any size if they have SingCore inside, guaranteed.

Clients may ask for a warranty on the large doors (that without SingCore inside could not be warranted) and the millwork can now offer the professional SingCore guarantee – in writing – that the doors with professional SingCore inside are guaranteed not to warp, bend, twist or otherwise fail for 50 years.

Working with SingCore

Millworks use either open edge or closed edge Sing Panel, whichever works best for the project at hand, as well as many options for skin types, solid blocking, custom lite cut outs, solid and exterior edging options.
