GENERAL DESCRIPTION

 

Glass Mat for Roofing is a non-woven material, composed of uniformly distributed glass fibers and bound by means of organic additives – mainly thermosetting resins. These form a mat, which after curing, is rolled up and ready for dispatch. Glass Mat for Roofing is not susceptible to atmospheric agents and UV rays, is supple and traction resistant, will not rot and is dimensionally stable. Its porosity makes it easy to impregnate, while it also demonstrates good chemical resistance and possesses excellent water-proofing, anti-corrosion and fire-protection characteristics.

 

USE

 

Glass Mat for Roofing provides effective reinforcement for bituminous coatings and improves their dimensional stability. These will not rot and will guarantee the waterproofing of roofs over many years. The inert nature of the glass mat means that it can also be used as an efficient separation layer under sheets of supple PVC. This glass mat is also used for the production of PVC or EPDM roofing membranes. Likewise it gives those membranes the desired dimensional stability. Glass mat is saturated by a continuous process with modified bitumen, PVC or EDPM, to obtain water-proof membranes to be afterwards placed on roofs (flamed, glued or mechanically fixed)
