Warm Roof Thermal Insulated
PIR insulation boards are Totally CFC/HCFC free rigid polyisocyanurate insulation boards, with plain perforated glass tissue facings on both sides.
The highly efficient closed cell foam core has an exceptionally low thermal conductivity and achieves required U-values with a minimum thickness. E PIR MG provides an ideal substrates for Asphaltech standard warm roof system.
