| Armstrong Rubber and Plastic foam insulation materials taking that oak moulds as base material close air bubble by that foam risen forms innumerable in inside of material, 0.026 W/mK, realizes heat preservation only because of the air heat conduction modulus therefore that Armstrong oak moulds foaming heat-barrier material is to but be not that oak moulds material depending on shutting the air steeping an inner. Shut resisting that bubble structure can't have outstanding at the same time aqueous vapour seeps through an ability , the vapor parclose forming built-in across, uses material now that the entirety insulating layer, be a vapour barrier , two kinds functions two combined into one. Even if material marks a wound outside do not affect an entirety's be separated by vapor sex. The tradition heat insulator is separated by a vapor but if rock cotton , the glass wool depend on supercrust aluminium foil only, once aluminium foil is derided , the tier of rock cotton , glass wool have no an inner at all because of being Kaikong structure detering aqueous vapour from seeping through an ability , aqueous vapour is extremely easy to seep into but is makes heat preservation become invalid. |
