Invisible polyester roofing carriers with fibreglass
Mar '17
Polyester carriers reinforced with glass filaments are coming up as material of choice for bituminous waterproofing membranes. These carriers impart features like flexibility, stability and shrink free to roofing material. These high-performance invisible carriers are being presented at the International Roofing Expo currently ongoing in Las Vegas, US.
The carriers reinforced with fibreglass filaments are a product by Freudenberg Performance Materials. These give the bituminous membrane outstanding dimensional stability and resistance over time, according to a company release. The fibreglass reinforcement also eliminates the phenomenon of thermal memory. Once applied to roofs, the membrane is shrink-free even when temperatures fluctuate.
“The combination of the flexibility of polyester together with the stability of glass gives our nonwoven carrier excellent runnability. This is especially the case when it is used at high temperatures and on high-speed bitumen lines,” says Federico Pallini, general manager Global Division Building Materials of Freudenberg Performance Materials.
The company’s value-added and highly functional solutions are suitable for even the most demanding roofing membrane applications. It manufactures both staple and spunbond nonwovens, in either standard versions or reinforced with fibreglass filaments to meet various market needs. The polyester carriers are invisible inside the bituminous membrane.
Freudenberg Performance Materials is a global supplier of innovative performance materials for applications such as automotive interiors, apparel, building materials, filtration, hygiene, medical and shoe components. (SV)
