Bare rock cladding

Rockbardage nu is an uncoated, single-density rockwool insulation board, machined on one edge to fit the specific geometries of cladding trays. It is available in two versions: straight lip or box lip with a 40 mm spacer. Advantages: Outstanding thermal and acoustic performance: 40 mm spacer to reduce thermal bridges and guarantee optimum thermal comfort. Thermal conductivity coefficient (λ) down to 0.033 W/m².K for optimum thermal insulation. High density and rigidity: Density of 50 kg/m3, the highest on the market, for improved flatness and a more aesthetic finish. Spaces out secondary framing and reduces the number of fixings per m². Increases the surface mass of the outer skin for better sound insulation. Easy to install for greater productivity on site: Excellent mechanical strength for easy handling. Easy to install, even in strong winds. Wide choice of finishes: Compatible with cladding manufacturers' Avis Techniques for great freedom of choice. Maximum fire safety: Reaction to fire Euroclass A1 (non-combustible). Fire resistance EI30 and E60 from 130 mm thickness to meet ERP building requirements. Excellent water resistance: Rot-proof and non-hydrophilic for optimum durability.
