Pitched Roof Renovation
Manufacturer: Saint Gobain Isover
Products: Premiumdach 1.000
Product category: Roofs
With the Premiumdach 1.000, Saint Gobain Isover offers a system solution for the renovation of pitched roofs. Both the Ultimate AP Supraplus-031 above-rafter insulation and the Ultmate ZKF-031 inter-rafter insulation felt are made of Ultimate high-performance mineral wool. Thanks to the continuous nominal value of thermal conductivity value of 0.031 W/mK, a U-value of less than
0.14 W/m2K can be achieved with a combination of 160-mm-thick inter-rafter and 100-mm-thick above-rafter insulation. Due to the significantly lower weight of the Ultimate solution compared to conventional rock wool, the desired U-values can be achieved even with low rafter heights and in the roofs of old buildings with limited load-bearing capacity.
