Will eps wall insulation panels keep my home equally cool in the summer as well as warm in the winter?” The answer is ‘Yes – these high quality insulation panels enhance the comfort in your home all year round.’ When the blocks are produced or molded, millions of air pockets are created which restrict the flow of heat. This action gives the expanded polystyrene sheets their insulating properties. Different specifications of foam construction require different R-values – different level of insulation for different applications and areas of a structure.
