BPP Polymer-modified bitumen membrane (-25°C) with 3-ply non-woven continuous filament reinforcement with high dimensional stability, stabilised with glass fibre. No-Fire Broof (t2) (t3)* Certification. INNOVA Line.
NOVA RF is a waterproofing membrane with waterproofing mass composition classified as BPE (Elastomeric Polymer Bitumen) according to Standard UNI 8818, comprised of:
• distilled bitumen modified with thermoplastic synthetic rubber elastomers with a radial configuration, which, due to the intrinsic and intimate homogeneity and stability achieved by the polymers used, gives the product reversible plastic deformation, thus recovering its initial dimensions within a variable time. The waterproofing mass is also characterised by very high cold flexibility, elongation and total springback, excellent fatigue strength and long-term performance.
• 3-ply non-woven heavy-weight CONTINUOUS FILAMENT polyester reinforcement with isotropic properties, stabilised with glass fibre for very high dimensional stability.
The outer surface of the membrane is covered with white ceramic slate granules, except for a strip along the edges without self-protection to facilitate overlap welding. The overlapping selvedge is coated with a hot-melt polyolefin adhesive film.
The bottom side is finished standard with a hot-melt polyolefin adhesive film.
NOVA RF has obtained Broof t2 and t3 classification for resistance to external fire exposure in special systems pursuant to UNI EN CEN TS 1187 and EN 13501-5
FIELDS OF APPLICATION
The membrane's very high mechanical strength and cold flexibility, combined with high resistance to weathering, allows its application as an exposed finishing layer of the continuous roofing sealing element in multi-layer systems, bonded to compatible membranes, or as an underlay for discontinuous roofing. It can also be applied as an exposed single layer for refurbishing works on the sealing element in polymer-modified bitumen membranes that are worn or no longer functional.
The product’s well-balanced components (layered compound and composite reinforcement), results in a membrane able to withstand the considerable thermal/mechanical strain generated on new or worn waterproofing systems, guaranteeing long-lasting high performance and safety.
The membrane is suitable for waterproofing roofs in general, pitched roofs, walls, tanks, and in all situations where a water barrier is required. It is particularly suitable in cases requiring a high capacity to absorb considerable structural strain (metal roofing, tensile structures, etc.).
Its characteristics make it suitable for all climates, even in particularly cold outdoor temperature conditions. It is not suitable for use on green roofs.
The membrane’s thermoplastic properties allow it to be regularly applied by torch or with a hot air generator, and in special situations, using compatible bituminous adhesives or by mechanical fixing. Due to its high adhesion, it can be applied to any type of substrate including: cement, brick, sheet metal, wood, all types of insulation panels, and other compatible membranes.
