The saving is calculated against an uninsulated roof, in Romanian climate conditions. The thermal resistance of the membrane assembly is R = 3,01 m²K/W, derived from INCD URBAN-INCERC test report no. 7039 / 18.10.2023.
The same installation position as in the two-layer version, but in the first stage two layers of Multistrat are installed, then Gold. The fourth layer, Multistrat again, is installed before the final board. Together with the sealed air layer, the assembly adds R = 3,01 m²K/W to what you have between the rafters.
