Product type: Roofing Surfacing Mat

1. COMPOSITION AND PRESENTATION

Roofing Surfacing Mat is mainly used as substrates for water– proof materials. 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 substrate with roofing surfacing 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 roofing surfacing mat substrate roofing are high strength, excellent uniformity, good weathering performance, leaking resistance, simplified process and longer life time.

2. PROPERTIES & APPLICATION

Properties:
--High porosity,
--Water resistance,
--High tensile strength,
--Corrosion resistance,
--Dimensional stability,
--Easy saturation by bitumen.

Application:
Roofing surfacing mat as an ideal substrate material is for asphalt roofing rolls and shingles. It can also act as the lining for roof insulation layers to protect polymer foam insulation from the damaging effect caused by chemical solvents in bitumen so as to prolong the lifetime of heat insulation layer.
