Rotaflam 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 hydroentangled nonwoven for 35 years.
Rotaflam Neo is made up of a fiberglass and/or polyester-based laid scrim, a nonwoven and a glass veil. The nonwoven is made through hydroentanglement, which 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.
By combining their know-how, the two companies 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. 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 also reduces the environmental impact of this solution.
