Thermal transmittance U-value (W/(m²K)
Calculation of the thermal transmittance is based on the numeric method according to EN ISO 10211 and EN ISO 10077-2.
- heat transmission resistance at the inner surface Rsi = 0.13 m2K/W
- heat transmission resistance at the outer surface Rse = 0.04 m2K/W
- The installation of insulation in the LIGNATUR element is not recommended. If insulation is required in the element due to the limited space, a special certificate from a specialist is required.
