Enertherm is a totally CFC/HCFC free, rigid polyisocyanurate foam insulation board, faced on both sides with perforated (mineral-coated) glass tissue. The highly efficient closed cell foam core has a low thermal conductivity and easily achieves required U values with a minimum thickness.
Enertherm is suitable for flat roofing use beneath British Standard and polymer modified mastic asphalt, mechanically fixed polymeric/bituminous single ply membranes, and built-up felt roofing systems. |
