Problems in Predicting the Thermal Properties of Faced Polyurethane Foams

Abstract

The thermal properties of polyurethane foams vary during service life depending on environmental conditions, the manner in which they are enclosed in the building partition, or if covered with facing membranes during their production. The effect of facing materials on thermal performance of the composites may range from a slight improvement of dimensional stability to a substantial reduction in the rate of loss of thermal resistance. Faced …
