The authors present a 3D gaseous transfer model and a simplified mechanical model. Thermal ageing and average volume change of ozone depletion potential foams with different facings are addressed. A formula has been suggested to correlate the elastic

Diffusion coefficients (D) of blowing agents and air in cellular plastic insulation are the key parameters in determining the thermal quality and dimensional stability of the foams. Measurement methods available for this purpose are briefly discussed

The commercially available closed-cell cellular plastic insulations are typically faced by gaseous impermeable metal foil to prevent transfer of gases from inside and from outside of the foam. Thus, the long-term aging properties of the foams will be

Chlorofluorocarbon(CFC)-based cellular plastics are facing the challenge of environmental protection. The cellular plastic industry has been looking for new blowing agents as alternatives for CFCs since the Montreal Protocol was signed in 1987. The p

A horizontal layer of expanded polystyrene foam (EPS) is widely used as a frost insulation of building foundations in the Nordic countries. The performance properties of the insulation depend strongly on the moisture level of the material. Experiment

Ageing of rigid closed-cell cellular plastic is the key problem to be solved in developing new foamed insulation. Diffusion-tight facing is one of the strategies to slow down the ageing process. As an example, n-pentane-based foam insulation was sele
