TECHNONICOL vapor barrier film

Polyethylene vapor barrier film

Application areas

The main function of the TECHNONICOL vapor barrier film is to protect the insulation from water vapor generated indoors. Vapor barrier significantly reduces the possibility of moisture condensation in the building envelope. Moisture, in turn, negatively affects the thermal conductivity of the structure and increases the risk of fungi, bacteria and mold.

Description of material

TECHNONICOL vapor barrier film is made of high-density polyethylene and is designed to protect the roofing pie structure from steam generated indoors. It has excellent water and vapor resistance, which minimizes the penetration of internal excess moisture into the building envelope.

Storage

  • Rolls must be stored on pallets, indoors or under a canopy in a horizontal position at a distance of at least 1 m from heating appliances.
  • The pallet can store up to 55 rolls stacked on top of each other.
