Fiberglass And Polyester Roofing Ply

Which is the better reinforcement for thermoplastic single ply roof membranes.

Fiberglass and polyester roofing ply.

Today over 99 of all thermoplastic single ply roofi ng membranes use a polyester reinforcement yet a few holdouts still contend fi berglass reinforcement is better. Henry 195 polyester fabric is white to off white with lay lines for 1 and 2 ply roof systems. Exceptional granule retention for long term weatherability. Since that time the tpo single ply roofing market has grown significantly and some industry reports state that tpo is the fastest growing segment of the u s.

Fiberglass roof is also called grd flat roof in some places which stands for glass reinforced polyester. Optimum porosity of the felt provides ready escape of air while allowing proper asphalt penetration at the time of mopping. Because of the high tensile strength and fully coated design pika ply hi tec 60 can be used in a number of roof applications. Pika ply hi tec granule is manufactured with white granules for surface protection reflectivity and aesthetic value.

It is ideal as the reinforcing component in cold process roofing and repair using either water based asphalt or acrylic emulsions or solvent type coatings or mastics. In the manufacturing process the reinforcement is cycled through a carrier roller and dipped into a saturation tank of the required bitumen coating dried and rolled for packaging. Product data sheet everguard separation sheets product data sheet 18 30 description gaf everguard single ply roofing systems include a full line of everguard separation sheets both non woven polyester beige in color and fiberglass fire resistant green in color mat. Pika ply hi tec 60 is a uniquely designed high strength sheet employing a premium polymer modified asphalt coating compound and a high performance fiberglass polyester combination reinforcement.

And like the names say it pretty much just consists of this strong material that is formed by adding small fibers made of glass which will help to strengthen it. In 1993 the original non reinforced tpo membrane was replaced with membranes containing reinforcing fabric. In this system fiberglass or polyester material is pressed in the middle of two rubberized asphalt layers. A 2 ply sbs roof system often known as torch down modified bitumen roof is gaining it s foothold in the industry at quite a rapid pace.

The use of fiberglass and polyester reinforcements in conventional built up roof systems is as follows. The roof felt acts as a stabilizer within the system. Tri ply ply 4 roofing felt is constructed with a fiberglass mat that is coated with the finest quality asphalt and is designed with optimum porosity to ensure a sound watertight membrane.
