Isocyanurate Roof Insulation Board

Trisotech Tapered Insulation is used to provide positive drainage of water from rooftop areas; Trisotech Tapered Insulation Systems include layout drawings to support the design and construction team in providing the best drainage based on the actual conditions of the roof.  Tapered Trisotech Insulation is recommended for use in combination with a wood fiber overlay board in hot and cold applied BUR and MB roof systems.  It meets ASTM C 1289-11, Type II, Class I, Grade 2 (20 psi) and Grade 3 (25 psi).


Trisotech Tapered Insulation consists of a rigid, closed cell polyisocyanurate foam core laminated on both sides to a black, fiber reinforced, non-asphaltic facer. Trisotech Tapered Insulation is CFC- and HCFC-free and the facers are manufactured from 100% recycled material (55% post-consumer, 45% post-industrial).
