4-rib roofing panel is suitable for a sloping roof with a small and medium angle of inclination. These panels have a trapezoidal outer surface. Thickness ranges from 60 to 200 mm. The PA4 mineral wool sandwich panels for roofing are suitable for roofs with a slope > 5° (3° only with additional insulation), their fire resistance rate is high, up to 240 minutes.
Mineral (rock) wool has good thermal insulation properties, which is confirmed by the declared thermal conductivity of λ = 0.04 W/m * K. The MW panels have extremely good noise insulation properties. The weighted average specific acoustic resistance coefficient is Rw = 32 dB, and the acoustic absorption coefficient is αw = 0.1. Density of mineral wool filler: ρ = 100-140 kg/m3. The fire resistance of sandwich panels filled with mineral wool allows the product to be classified as: A1 – Non-flammable
The results of fire resistance tests of the MW panels show very high fire resistance indicators. Depending on the thickness and type of panels, they have a fire resistance class ranging from EI 30 to EI 240.
