A specialized vapor barrier foil made of two layers of polyethylene foil, reinforced with a polypropylene mesh and metallized on one side with a layer of aluminum. By using a metallization layer, the product reflects thermal energy, enhancing the insulation effect, prevents the attic's airtightness, and at the same time constitutes a barrier against dust, wind and water from the outside. Reinforcement with polypropylene mesh guarantees high tear resistance, which prevents mechanical damage.

Features

• prevents condensation of water vapor over the thermal insulation
• protects thermal insulation against the harmful effects of moisture
• high resistance to tearing and mechanical damage
• prevents the occurrence of mold and fungus in
• prevents loss of heat energy
• protection of the roof structure and thermal insulation layer against the inflow of water vapor from the rooms
