Therma TT47
Therma TT47 is a rigid tapered PIR roof insulation board faced on both sides with a coated glass tissue facing. It provides insulation and drainage in one, designed to enhance water drainage from flat roofs, which are waterproofed with fully adhered single-ply and cold applied waterproofing. We provide a supporting design service to identify the most cost-effective tapered system design solution for flat roofs to meet rainwater run-off and insulation requirements.
