C-DH MAT( Roofing mat)
C-DH mat is mainly used as substrates for water-proof roofing materials. It is characterized by high tensile strength, corrosion resistance, dimensional stability, water resistance, high porosity and easy saturation by bitumen. The longitudinal strength and tear resistance can be improved further by incorporating reinforcements into the mat across its whole width Perforated mat is also available when the mat comes out from a particular punch process. The asphalt roll roofing substrated with C-DH mat can overcome problems existing with paper felt such as low-temperature cracking,high-temperature melting liable to aging, rotting and leaking. Other advantages with C-DH mat substrated roofing are high strength, excellent uniformity, good weathering performance, leaking resistance, simplified process and longer ife time. C-DH mat is an ideal substrate material for asphalt roofing rolls and shingles C-DH mat can also act as the lining by chemical solvents in for roof insulation layers to protect polymer foam insulation from the damaging effect caused bitumen so as to prolong the lifetime of heat insulation layer.
