The layer of foamed thermal ,insulation, is the weakest member of the ,insulation system, and therefore the structural response of the ,insulation system, will depend largely on this layer. Elastic deformation of the system leads to a reduction in volume of the ,insulation system, and an increase in density and thermal conductivity of the foam layer, which leads to an increase in the U-value of the ...
