Chomarat launches roofing reinforcement Rotaflam Neo

Paris-based roofing products developer Chomarat has launched Rotaflam™ Neo, which the company calls a new generation of reinforcements for roofing felt. The product was developed in collaboration with hydroentanglement non-woven specialists Norafin, based in Bonn, Germany.

Unique in its market, the reinforcement offers the benefits of both glass and polyester and combines the performances of laid scrim (strength and dimensional stability) and nonwoven materials (puncture, fire and tear resistance) in a single layer.

Rotaflam Neo is made up of a fiberglass and/or polyester-based laid scrim, a non-woven material and a glass veil. The non-woven material uses a water-jet binding process that guarantees the performances of the laid scrim. Using a laid scrim that combines glass and polyester offers two benefits: the glass adds stability on the roof, but also on the membrane production lines, while the polyester brings elongation and strength.
