Lembit NRO fireproof weldable roofing paper is used to make the top layer in multilayer roofing. It can be used to make new or renovate old roof coverings. Due to its high strength and elongation capacity, it is recommended to apply it to insulation exposed to mechanical factors. The roofing felt is fastened to the base by welding using hot air or after training using a gas burner and mechanical fasteners.

Papa is used in systems that allow the implementation of roofing in terms of fire resistance - REI; layered roof covers according to PN-EN 13501-2: 2005. The test was carried out for REI according to PN-B-02851-1 and PN-EN1363-1: 2001 for REI 15, RE 20, REI 30, REI 45. Roof covers and load-bearing parts of layered roof covers are classified according to the standard in resistance classes REI fire.

• Product use: Top covering, for single or multi-layer coatings. Papa meets the criteria of increased resistance to external fire Broof (t1) and is used in systems that allow roofing in the field of fire resistance - REI.
