Cellofoam North America

Cellofoam North America C3 (2.5" to 3.5") x 4' x 4' Tapered EPS Panel 1.25 Lb. Density

Cellofoam North America

Product Description

Tapered EPS Panel comes with below features:

Designed to provide positive drainage of water. The added thickness to produce slope to drain is a positive factor in today's energy conscious society.
The roof consists of pre-designed pieces of expanded polystyrene.
Tapered can be supplied in various densities.
Each piece is labeled as it is manufactured to coincide with the actual shop drawing, thus eliminating guess-work by the installers as to the placement of the insulation.
Saddles and crickets are available as required.
