Roofing support panels

The ISOLtop product line features insulation panels for commercial roofing. These panels are available in varying forms: regular or high density, natural, impregnated and coated, as well as in different dimensions and thicknesses. ISOLtop panels provide a thermal value of R3/inch and a compressive strength equal to or higher than 45 psi. ISOLtop panels are recommended as an overlay for other insulation materials and provide excellent support when applying asphalt and waterproof membranes.
