It’s so easy to use Sing Panels to make beautiful doors of any size. Sing Door Panels have a ten year warranty for internal use. For external use, we offer marine grade plywood. If you need strength, lightweight, insulation, and true flatness, Sing has the answer!

Patented Sing Core: We put a torsion box in the SIP panel to make it better. The other names for our panels include sandwich panel, honeycomb panel and lightweight panel.

Sing Performance

Keep your house warm with Sing doors available with an EPS or Urethane core. Available in tough weather resistant skins like aluminum, stainless steel, fiberglass and marine grade plywood, Sing exterior doors last in even the toughest of environments. Each material has their own strengths. Galvanized metal skins provide protection in areas near saltwater and can be painted. FRP provides moisture protection. Wood stave skins provide much more protection than veneer skins.

EPS is our standard core that offers an R-value of 3.5 per inch of thickness and for those harsh environments the R-value doubles using our Urethane core offering a 6.5 R-value per inch of thickness.

Sing Beauty

Wood skins that are like no other. Sing also offers and wide variety of natural wood skins to give that timeless look of beauty and precision craftsmanship.

Sing exterior door panels are built to last. Using our patented SingCore technology, they hold up to the great test of time.

Based out of the Pacific Northwest and using the area as a testing ground, our doors can stand up to the harshest of elements.
