Thermataper TT47 is a high performance tapered insulation. It is designed to enhance water drainage for flat roofs waterproofed with fully adhered single-ply, partially bonded built-up felt, mastic asphalt, and cold liquid applied waterproofing. Thermataper TT47 comes with a supporting design service. This ensures that the most cost-effective solution for a roof is identified and that the end result is a tapered system design that meets the roof’s rainwater run-off and insulation requirements.
