Thermally insulated panel

摘要

A thermally insulated panel comprises a pair of spaced facing channels, preferably of metal, which are fixed together in a structurally secure manner by use of a serrated rigid plastic sheet disposed therebetween and by a closed-cell foamed polymeric material which fills the voids between the rigid sheet and the channels. The channels are bound together and the spacing between them is sealed by means on the rigid plastic sheet which, in addition to securing the channels together, is permanently and monolithically sealed in place by the closed-cell foamed polymeric material. A thermal break is formed to prevent loss of heat across the shell of the panel.
