15 Roofing Felt Asphalt Saturated Organic Roofing Felt Roll Waterproof Sheet
Introduction
asphalt roofing felt is a heavy-weight asphalt roofing felt made of a specially formulated organic sheet which has been fully saturated with waterproofing asphalt.
Roofing felt (felt paper,asphalt felt paper) is a sheet material(raw paper) saturated with asphalt,similar totar paper,used in building construction.the term felt comes from the historical method of making the base material.Felt is an unwoven fabric that is produced by matting fibres under pressure.The fibres form the structure of the fabric.
Characteristics
Anti-leaking and tearing: passed 110 mph wind test and 4-hour water spray test with cap and roofing nails.
Lightweight: faster and quicker, 432/216 sq.ft coverage per roll, easy to carry and easy installation.
Excellent tensile: CD>=300N MD>=300N
Endurance: up to 120 days exposure for roof finishing
Wrinkle free: lay flat, stay flat, but flexible
Anti-skidding: textured surface provide good walking surface during installation
Specification: Roll width=91.4cm Roll length=44m Unit weight=200--1200 gams/m2
(Size and other specification can be changed as required)
Asphalt roofing felt is conformity with ASTM standards of the USA
The specifications of the roofing felt are ASTMD-4869#15 ,4869#30 and ASTMD-226#15 ,226#30,.
