IMPROVEMENTS IN AND RELATING TO INSULATING SHEET MATERIALS

摘要

An insulating and barrier sheet material includes a core layer of a paper and outer linings of plastics material one of which includes a metallised plastics film. The sheet material is pliable and thin and can be used in a number of installation system situations to provide insulation and in some situations to provide a waterproof barrier to protect timber framing materials and prevent damage caused by water leakages.
