Abstract
Abstract A support net is covered on each side with a carrier web having an external metal IR-reflecting coating and superposed thereon a protective coating which is substantially transparent to infrared radiation. The metal coatings and the protective coatings are thin enough to be substantially permeable to water vapor. The support net carries the load and allows water vapor to pass through because of its open net-like structure.
