    Abstract: Thermal insulation structures include a polymer foam layer adhered to a multi-layer sheet having a non-cellular layer of a heat-resistant thermoplastic and a second non-cellular layer of a polylactide resin. The polylactide resin is a surprisingly good barrier to the diffusion of atmospheric gases into the foam layer and of blowing agents out of the foam layer. Accordingly, the diffusion of atmospheric gases and blowing agents is retarded substantially. This greatly reduces the loss of thermal insulation capacity of the structure due to the replacement of the blowing agent with atmospheric gases. The multi-layer sheet exhibits excellent thermal stability, even when the polylactide in the polylactide layer is highly amorphous.
