Eurovent BAU LDPE Construction Foil 0.2–0.5 mm, 4 × 25 m, 100 m²

Eurovent BAU construction foil is an LDPE polyethylene moisture barrier film designed to limit moisture migration into floors, screeds and building structures. It is suitable for professional construction and renovation work where a protective or moisture-resistant separation layer is required.

Eurovent BAU is manufactured from low-density polyethylene (LDPE), providing good mechanical strength and tear resistance. The material is resistant to weather-related exposure, including rain, snow and dirt.

With an Sd value of approximately 50 m, the foil provides high resistance to water vapour diffusion. Its primary applications include floor and screed underlays, as well as protective layers for thermal and acoustic insulation.

The foil is available in 0.2 mm, 0.3 mm and 0.5 mm thickness options. Each roll measures 4 × 25 m, providing 100 m² of material.

In addition to moisture protection, Eurovent BAU can be used as a temporary protective covering during construction, installation and finishing work.

Applications & Usage

Eurovent BAU moisture barrier foil is primarily used as a separation and moisture barrier layer in floor constructions. It can be installed beneath floors, screeds and concrete layers according to the specified building design.

The foil can also serve as a protective layer for thermal and acoustic insulation.

During construction and finishing work, Eurovent BAU can be used as temporary protective sheeting for:

• Windows and joinery

• Roof surfaces

• Facades

• Building materials

• Installation and finishing areas

Related System Products

Depending on the construction design and installation requirements, Eurovent BAU can be combined with:

• Eurovent sealing and adhesive tapes – for sealing foil overlaps and joints.

• Eurovent vapour control membranes – for additional vapour control where a separate vapour barrier layer is specified.

• Eurovent geotextiles and protective accessories – for layer separation and substrate protection during screeding and concrete work.

The selection of additional materials depends on the specific floor or building assembly.
