Abstract

Thermal insulation having a U-value of 0.2 or less is obtained by sandwiching a rigid foam core between two cover sheets at least one of which is of perlite having a thickness of at least 0.6 inches, a perlite content of at least 30% and a sizing content of not more than 35%. When the other sheet is not of perlite it may be roofing felt or paper.
