InsulFoam Tapered Roofing Insulation

Tapered Roofing Insulation

InsulFoam I, VII, II, IX, XIV and XV: Flat & Tapered EPS Roofing Insulation

InsulFoam Taper is an engineered insulation consisting of a superior closed-cell, lightweight expanded polystyrene (EPS). InsulFoam Taper is cut from the same high-quality EPS as our flat InsulRoof products, and meets or exceeds the requirements of ASTM C578, Standard Specification for Rigid, Cellular Polystyrene Thermal Insulation.

InsulFoam Taper offers a long-term, stable R-value and has excellent dimensional stability, compressive strength and water resistance properties.


InsulFoam Taper is well-suited for single-ply roof applications that employ ballasted, mechanically fastened TPO, PVC, EPDM and CSPE with a slip sheet, as well as low-sloped built-up, modified bitumen and fully adhered single-ply roofs that incorporate cover boards. Consult local building codes and membrane manufacturers for system requirements.
