WebPolyurethane is a closed-cell foam insulation material that initially contains a low-conductivity gas in its cells. As a result of the high thermal resistance of the gas, spray polyurethane insulation typically has an initial R-value around R-3.4 to R-6.7 per inch. In comparison, glass wool typically has an R-Value of only R-3 to R-4 per inch. Webthe density range of polyurethane density reported in the literature [1]. The different relative densities obtained vary from 0.33 up to 0.85. This is a density range more spread than in previous published works devoted to high density polyurethane foams [1,10,14,15]. For the latters, the rela-tive density was limited to a maximum of 0.6. 3 ...
