Construction foil
BAU
Eurovent® BAU construction foil is made of low-density polyethylene (LDPE). It limits moisture penetration from the surrounding environment towards the building structure. The material provides high mechanical strength and resistance to weather conditions such as rain, snow and contamination.
Advantages
- Waterproofing
- Tear-resistant
- UV-resistant
- Quick and easy installation
Application and Technical Data
Eurovent® BAU construction foil is primarily used as an insulating layer beneath floors, screeds and other floor constructions. It can also be used as a protective layer for thermal and acoustic insulation used in construction.
Thanks to its mechanical properties, Eurovent® BAU can also be used as a protective foil for windows and doors, roof surfaces, façades and building materials during installation and finishing works.

System Products
To achieve maximum protection of floors, screeds, and structural layers, Eurovent® BAU should be used together with:
- Eurovent® sealing and adhesive tapes, which ensure airtight joints and protect against moisture penetration,
- Eurovent® vapour control membranes, which additionally protect building structures against water vapour migration from the interior side,
- Eurovent® geotextiles and protective accessories, which improve separation and protect the substrate during screed application and other wet construction works.
The use of complete Eurovent® system solutions ensures effective protection of working surfaces, increases the durability of underlay layers, and minimizes the risk of damage during construction.
GOOD TO KNOW
Is BAU a typical attic vapour control membrane?
That is not its primary role. BAU is an LDPE construction foil intended mainly as an insulating and protective layer for floors, screeds and building work.
What does it do under a screed?
It limits moisture migration and protects adjacent layers from construction moisture, in accordance with the floor design.
Can BAU protect materials during renovation?
Yes. Its mechanical properties allow it to be used as a protective foil during installation and finishing work.
BAU or a conventional roof vapour control layer?
This depends on the application. The proper roof vapour control layer should be made using a product specified for the particular construction build-up.
Is BAU waterproofing for every below-ground application?
It should not be treated that way. Damp-proofing or waterproofing must be selected to suit the specific building solution.
