This R value is larger than the required 1.00 and is therefore acceptable.
In the case of a known K and thickness of alternative materials to be used in combination,
convert all K values to R by dividing the thickness of each material by its K value. Add R values
of the proposed materials as shown in the previous example.
Exemple:
K value = 0.75
Thickness = 1
R value = Thickness/K = 1/0.75 = 1.33
