Chomarat has launched its new generation of reinforcements for roofing felt: Rotaflam Neo, developed in collaboration with Norafin.
Chomarat claims that this is the only reinforcement of its kind on the market, because it offers the benefits of both glass and polyester and combines the performances of laid scrim (strength and dimensional stability) and nonwoven materials (Puncture, Fire & tear resistance ) in a single layer.
According to Chomarat, Rotaflam Neo is the result of a joint development between itself and Norafin. Rotaflam Neo is made up of a fibreglass 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. Chomarat explains that using a laid scrim that combines glass and polyester offers two benefits: thanks to its intrinsic properties, the glass adds stability on the roof, but also on the membrane production lines, while the polyester brings elongation and strength.
“By combining our know-how, we can offer a reinforcement that rises to the challenges of the waterproofing market, offering improved performance, while reducing the thickness of the membranes. The reduced weight of the bitumen significantly cuts the production costs of the membranes,” explains Marlene Berthouze, Roofing Market Manager at Chomarat. Moreover, the membranes produced with Rotaflam Neo pass all the European fire resistance tests (BROOF T1,T2, T3). “Rotaflam Neo improves the fire resistance of the waterproofing membrane and does away with the need to include certain chemical additives in the formulation. Which means that the environmental impact of our solution is also reduced!” she adds.
“Rotaflam Neo is the perfect addition to our range of reinforcements, and it was well received by the entire profession at the Waterproof Membranes 2015 conference in Bonn,” explains Raphaël Pleynet, Business Director, Composites and Construction Europe at CHOMARAT.
