Many educated homeowners demand that their trade professionals use SingCore products to build their dream homes. SingCore does not make the doors themselves, but after researching our patented SingCore materials many homeowners will not allow other building materials to be used. (See our homeowner’s page.)

Doors are a very critical component and must withstand constant impact, use and weathering, be sound-deadening and long-lasting. The solution is our patented SingCore materials. See our new C Series line of Affordable Barn Door and Sliding Closet Doors.

No matter what style doors you envision for your home, or if you need a barn door for your barn, patented SingCore panels can build the strongest yet lightweight, long-lasting, insulated, and true flat doors.  This means SingCore doors are not dangerously heavy or difficult to use, they never warp or twist (which prevents damage to hinges and fingers), and they will last for many decades with normal use.  Our patented SingCore panels are made with our patented water-resistant, formaldehyde-free, eco-friendly glue and made in the USA.

If you need a sliding door for your barn, barn doors made with our patented SingCore panels are the most long-lasting, insulated and sturdy. Exterior sliding barn doors can be beautiful following installation, but after time, problems develop due to expansion and contraction from weather exposure causing them to warp, twist, and crack and compromising the overall performance of your sliding barn door. Even a 1/4″ deflection can compromise a barn door’s function and aesthetically pleasing quality. SingCore’s true flat guarantee is why high-end millworks and designers seek out SingCore for extreme weather and temperature-controlled environments, and that guarantee will ensure your barn door works well for many decades.

Customizing options that can help make your order more specific are size and location of internal wood (or other specified material) such as blocking, stiles and/or rails (solid wood edges on 4 sides of the Sing panel) and lock blocks or nailing for added siding over the surface of the Sing panel.  The best way to show us what you need is to by provide us with a simple drawing to show the location of hard point.[/wpex]


The standard ready-to-ship panel condition is, “untrimmed.”  This leaves unfinished exterior edges that may have exposed adhesive and are ½ inch over-sized for trimming at your location. An additional fee will be assessed for trimming and sizing in our factory.

All trimmed edges are 1/2 inch over width and 1/2 inch over length.  After trimming, your Sing Panel will be 1/2 inch less (4 x 8 will be 47.5 inch x 95.5 inch).

Standard solid wood edging with 1.5 inch will be reduced to 1.25 inch after trimming.[/wpex]
