Rockacier B Nu Energy under bituminous membrane for flat metal roof (FR)

[Product by ROCKWOOL France S.A.S. Please check availability in your country] ROOF COMPOSITION from inside to outside : - Ribbed steel sheet 0.75mm (wide span possible) - ROCKACIER B NU ENERGY stone wool insulation: 100mm to 160mm - Metalic and Plastic fastening (Cold bridge breaking) : 4 fasteners / m² (χfixation = 0.001 W / K) - Two bituminous layers membranes mechanically fixed ROCKACIER B NU ENERGY is an uncoated double density bare stone wool insulating board. The orientation of the fibres is controlled during manufacture, providing enhanced mechanical performance. APPLICATION : It is used for inaccessible flat roof insulation made of ribbed steel sheets or wooden elements (Classe B). ADVANTAGES : - Best alliance between thermal performances (λ and thermal confort) and fire safety (Non-combustible Euroclass A1). - Excellent mechanical strength due to straightened fibres. - Acoustic performance. - More efficient installation due to the Long Length format (2400x600mm and 2400x1200mm, not available for all thicknesses). - Dimensional stability. - Rot-proof and non-hydrophilic.
