Advantages and disadvantages of aluminium film and aluminium foil film for waterproof coiled material
3, aluminum foil is aluminum sheet is very thin, because a single foil easily, and PE use a composite plastic film, some manufacturers will buy their own pure aluminum foil, combined with a thin layer of plastic film, this use is not easy to break.4, because the aluminum foil is a metal sheet, the strength of the coiled material is improved. The aluminum foil on the modified asphalt membrane, when exposed, although the durability will be longer than the aluminum film, and with the increase in service life, the foil will crack and oxidation, it is estimated that five years can be used. This is related to the use of the environment and the quality of the material.5, the same material with the two cladding, the comprehensive performance of the service life of aluminum foil almost, a little longer. Construction methods are basically the same.
1, at present our waterproof material standard seems to have no aluminum foil surface waterproof coiled material, the original self-adhesive coil has a variety is aluminum foil, before, it seems that SBS modified asphalt roll also has a kind. The thickness of aluminum foil affects the mechanical properties of the coil, and can not be compared without standard.2, aluminum film is in PE or PET plastic film on the aluminum plating, and its essence belongs to plastic film, in exposed use, generally two years plastic film will aging, completely lost the original reflection effect.
There is no pearl cotton in the middle of the aluminum mold, the heat insulation effect is not good.Aluminum foil film outer layer of aluminum foil is thinner, waterproof effect is better than aluminum film.
