STEICOflex 036
Flexible thermal insulation from wood fibre
Thermal conductivity 036 – Best protection against cold among natural insulating materials
With a thermal conductivity of λ 0.036, STEICO flex 036 has the lowest thermal conductivity of all common natural insulating materials. In other words: it insulates best. It can be used to significantly reduce the heating energy requirement of a building – and with it the heating-related CO 2 emissions. The thicker the insulation layer, the more CO 2 emissions - year after year. This adds up to a significant amount of CO 2 over time
Thanks to its high heat storage capacity, STEICOflex can buffer summer heat over a period of several hours. The majority of external heat fails to penetrate the building fabric and overheating of the living space is both delayed and reduced. During the evening and night time, when it is cooler, the stored heat can then escape outwards again. Wood fibre insulation materials ensure a better heat protection than synthetic insulation materials.

More about STEICOflex 036
STEICOflex makes an important contribution to noise protection. The high bulk density (volume weight) in combination with the unique fibre structure allow for high-performance sound insulation constructions.
Protection against moisture
The combination of rain protection and openness to diffusion ensures maximum protection against moisture.
Excellent insulation properties in winter
The so-called lambda value (λ) is important for protection against the cold. The lower the value, the better the insulation performance. With a nominal value of λD 0.037, STEICO protect 037 has the lowest thermal conductivity that can currently be achieved with facade insulation made from renewable raw materials.
A lower lambda value allows thinner insulation layers and enables greater energy savings.
Very good sound insulation
Where insulation systems made of rigid foam can even degrade sound insulation, STEICO protect 037 insulation boards make a valuable contribution to a quiet living atmosphere - thanks to their special fiber structure.
