Flat Roof Insulation

Jumbolene® Flat Roof Insulation is a semi-rigid board, made of low density, closed cell polyethylene foam. It is ideal as an under or over roof membrane insulation. It does not break and can take the weight of ballast or pavers if the roof area is also subject to pedestrian traffic. The product can be easily cut and shaped to suit a variety of geometries. Jumbolene® Flat Roof Insulation is available in a range of thicknesses to meet required R-values.
