Polyethylene foam foiled by metalized film is the polyethylene foiled by a film with aluminum spattering. The multipurposeness of this material consists in heat-reflecting layer which allows decreasing the warmer thickness and makes it one of the most effective types of heat insulation. It is mainly used in building works for insulation and isolation of different buildings and engineering constructions. It has the same properties as the polyethylene foam: freeze-thaw resistance, water proofing, high absorption qualities, vapor- and soundproof, high elasticity and tension. It causes no harm in everyday use.
