Question

What is the specific heat, thermal conductivity, density of polyurethane foam?

Answer 1

Insulation materials with higher thicknesses have lower long-term thermal conductivity values in general. The density of rigid polyurethane foam (PUR/PIR) used for building thermal insulation typically ranges from 30 to 45 kg/m3. For some applications, however, it can achieve 100 kg/m3.
