Invisible but essential

The worldwide leader in the roofing market will be presenting its extensive range of high-performance nonwovens used as carrier materials for bituminous waterproofing membranes at the International Roofing Expo. A highlight will be the polyester carriers reinforced with glass filaments. Once inside the bituminous membrane, Freudenberg Performance Materials polyester carriers are invisible, but essential to offer outstanding performances.

“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. In addition, our carrier reinforced with fiberglass filaments gives the bituminous membrane outstanding dimensional stability and resistance over time. Using the fiberglass reinforcement also eliminates the phenomenon of thermal memory: once applied to roofs, the membrane is shrink-free even when temperatures fluctuate.

Invisible, but essential
Freudenberg´s value-added and highly functional solutions are suitable for even the most demanding roofing membrane applications. The company´s cutting-edge technology enables it to manufacture both staple and spunbond nonwovens, in either standard versions or reinforced with fiberglass filaments to meet any market needs. The polyester carriers are invisible inside the bituminous membrane, but essential for its performances. 

Long-established presence in the American market

Freudenberg is committed to the American market by running a production site in Macon, Georgia, since 1983. To date, the site has been manufacturing and providing more than 10 billion square yards of polyester roofing carrier that protect buildings from water, worldwide.
