Universal insulation angle fillets for use with flat roofing. Supertherm Universal Angle Fillets comprise a protective facing, factory laminated to a high performance CFC-free rigid polyisocyanurate foam insulation board. The top surface comprises a 3.2mm rigid bitumen protection board and the foam backing is chamfered to accommodate variations in internal angles, and finished on the reverse face with another strip of protection board to provide dimensional stability.
The dense and uniform nature of the protection board facing resists damage and makes a sound, stable base for bituminous roofing membranes to be fully bonded direct to the board by torch application, hot bitumen or cold adhesive. It also makes an ideal surface to receive self-adhesive membranes, polymeric roofing and high performance liquid systems.
