NettetPU insulation materials are based on ridgid foam system with a close cell content of > 90%. Its material density usually range from as low as 30 kg/m3 to 100 kg/m3. In some cases high density systems of up to 500 kg/m3 are required. The thermal conductivity of ridgid foams are WLS 024, 025, 028, 030. NettetIn general, thermal insulation is primarily based on the very low thermal conductivity of gases. Gases possess poor thermal conduction properties compared to liquids and solids and thus make a good insulation material if they can be trapped (e.g., in a foam-like structure). Air and other gases are generally good insulators.

NettetStarting in the mid-90s, Trafag introduced gas density sensors. They are the first choice when continuous and long-term, drift-free insulating gas density measurement and data acquisition are required. Exposure of an oscillating quartz to gases of different densities causes a shift and damping of the resonant frequency. NettetROCKWOOL Comfortboard® 110 is a rigid, high-density, stone wool insulation board used as exterior continuous insulation in commercial applications.

Nettetstores, where they have to fulfill both insulating and mechanical requirements [3,4]. There is a number of references illustrating the effects of foam density on mechanical properties of PU foams [2,5]. The data are largely dependent on foam producer, as used substrates and production technology decide on intrinsic structure and foam density, and NettetHigh-density batts for a 2 by 6-inch (51 by 152 mm) frame wall offer R-21, and high-density batts for an 8.5-inch (216-mm) spaces yield about an R-30 value.
