BPP Polymer-modified bitumen membrane (-25°C) with 3-ply non-woven continuous filament reinforcement with high dimensional stability, stabilised with glass fibre. High-reflectance membrane. No-Fire Broof (t2) (t3)* Certification. INNOVA Line.


NOVA RF REFLECTA 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.
A special feature is the coating on the top side in special white slate chips with high solar reflectance (SR 0.699 / SRI 84.8%). The high reflective properties combined with high emissivity (E 0.911) allow less heat absorption during the day on the roof where the membrane is installed, and the subsequent transmission and emission of this thermal energy in the infrared range. This means a lower operating temperature for the membrane, and therefore a lower temperature in the rooms below the roof, leading to benefits in terms of energy savings and the longer service life of the membrane. Moreover, the edges of the top side are without self-protection and are coated with a hot-melt polyolefin adhesive film to facilitate overlay welding. 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.

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.). The high reflectance also ensures the highest possible yield of any installed PV systems thanks to the low operating temperature and increased radiance of the roof’s extrados.
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.
