  • Reinforcement offers advantages of both glass and polyester
  • Combines performances of laid scrim and nonwoven materials
  • Joint development between Chomarat and Norafin

Chomarat has launched a new series of reinforcements for roofing felt: RotaflamTM Neo, developed in collaboration with Norafin. This is the only reinforcement of its kind on the market that offers the advantages of both glass and polyester and that combines the performances of laid scrim (strength and dimensional stability) and nonwoven materials (Puncture, Fire & tear resistance ) in a single layer.

Joint development between Chomarat and Norafin

RotaflamTM 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.

Combination of fibreglass and/or polyester-based laid scrim, non-woven material and glass veil

RotaflamTM 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: due 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.

The membranes produced with RotaflamTM Neo pass all the European fire resistance tests (BROOF T1,T2, T3).
