PCT No. PCT/GB82/00127 Sec. 371 Date Dec. 14, 1982 Sec. 102(e) Date Dec. 14, 1982 PCT Filed Apr. 28, 1982 PCT Pub. No. WO82/03821 PCT Pub. Date Nov. 11, 1982.Insulating material is formed in a continuous strip and comprises a web of flexible impervious polymeric material in which individually spaced elongate pockets have been formed transversely across the elongate strip. Insulation material is located in the pockets which are covered by a sheet of impervious foil material, such as aluminium foil, which forms one outer surface of the completed web of insulating material. The foil is heat sealed to the polymeric material so that the insulation material in the pockets is totally encompassed by impervious material, thus minimizing deteriorization of the insulation properties of the insulation material. The insulation material can be foamed in the pockets or can take the form of powder or foam granules. The construction of the web of insulating material allows the material to be folded into a relatively small volume for the most economic transportation, while in use as an insulating material, the pockets are butted together to form a most effective insulation layer for pipes in buildings, loft insulation, cavity wall insulation or insulation attached to preconstructed wall portions of timber frame houses. |
