Semi-rigid board is composed of a mineral fortified asphaltic core formed between two saturated fiberglass felts. This board is designed to be used as a substrate material in low-slope roofing. It can be installed over wood, rigid insulation or as a recovery board over an existing roof surface to be re-roofed.
BENEFITS
Compatible with most bitumen and built-up roofing (BUR) systems

Mold resistance
Bitumen Impregnated Board is manufactured from high-grade slow-growing Scandinavian wood fibres which are bitumen impregnated and compounded into a compressible non-extruding board.
The boards are made from fibre board with an asphalt layer running through it. They can be used in a number of situations including, but not limited to, roads, ramps, pavements, pedestrian areas and concrete floors. They are compressible but have low distortion.
