CHOMARAT’s Eco-Friendly Roofing Reinforcements Offer Benefits of Glass and Polyester

CHOMARAT announces the launch of its new generation of reinforcements for roofing felt: Rotaflam^TM Neo, developed in collaboration with Norafin.

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 non-woven materials (Puncture, Fire & tear resistance ) in a single layer.

Joining Chomarat and Norafin technologies for excellent products
Rotaflam^TM Neo is the result of a joint development between Chomarat, which has been active on the roofing market for 40 years, and is an expert in the design and production of laid scrim, and Norafin, a specialist in hydroentanglementnon-woven for 35 years.

Rotaflam^TM 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. 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.

Combining improved performance and thinner membranes
"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^TM Neo pass all the European fire resistance tests (BROOF T1,T2, T3). "Rotaflam^TM 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^TM 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.
