About Flat EPS Roof Insulation
ACH Foam Technologies' Foam-Control® Flat Roof Insulation provides high long-term R-Value of EPS and labor-saving face laminates. Suitable for use with all roofing membrane materials, expanded polystyrene (EPS) roof insulation is compatible with loose-laid and attached single-ply membranes, conventional built-up roofing or modified bitumen systems.
Foam-Control® Flat Roof Insulation is unfaced EPS and is
suitable for use with loosely laid single-ply membranes. Flat EPS Roof Insulation is also used with conventional BUR and mechanically or adhesively attached single-ply and modified bitumen membranes when field-applied coverboards are used. Boards are standard 4'x4' and 4'x8' sizes.
