Web15 de jun. de 2024 · Mechanical properties: high-density foam has greater mechanical properties (compressive stress resistance, tensile strength, tear strength, thermal shrinkage) then low-density foam. Insulation properties: low-density foam has a lower λ-value then high-density foam (therefore it has better thermal insulation behavior). 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.
