Knauf StoneWool FKD-S Thermal λ=0,035 W/mK, A1 1000X600X50mm

DESCRIPTION

FKD-N Thermal is a solid rock wool board specially designed for external thermal insulation systems. The product has improved thermal characteristics, lower thermal conductivity coefficient λ = 0.034 W/mK which contributes to improving the thermal efficiency of the building. The product is non-combustible class A1, offers sound insulation, is resistant to ageing and chemically inert. It also has absolute transpiration with a coefficient of resistance to water vapour diffusion, μ=1 (the same as air) and therefore helps to maintain the best possible "breathability" of the masonry.

The dimensions of the product do not change when temperature fluctuations are strong.

ADVANTAGES

Fire protection - Fire reaction class A1 according to EN 13501-1, practically non-combustible material

Thermal insulation - Low coefficient of thermal conductivity λ= 0,034 W/mK

Sound insulation - Excellent sound insulation due to the structure of the material's fibres

Transpiration with a resistance to water vapour diffusion coefficient of μ=1
