Vapour barrier film – price

Price is an important factor when choosing a vapour-permeable membrane. The Homeseal LDS 100 polyethylene vapour barrier offers excellent value for money. This product is characterised by high resistance to damage and moisture, ensuring effective protection of the building structure for many years to come. The price of a vapour barrier film depends on the area, but as mentioned above, it is a worthwhile investment in the long-term protection of the building.

Installing a vapour barrier on the roof

Homeseal LDS 100 is an effective vapour barrier membrane for roofs, particularly recommended for structures with a layer of mineral wool. Installed on the inside of the building, it prevents water vapour from penetrating the insulation layers, protecting them from damp. Thanks to its high resistance to mechanical damage, the membrane is suitable for both pitched and flat roofs. Its width and length allow for the efficient covering of large roof areas without the need for numerous joints. Using this product as a vapour barrier beneath mineral wool extends the service life of the entire roof system. This solution is recommended both for new-builds and for the thermal retrofitting of existing buildings.

Using a vapour barrier film in the bathroom

The Knauf Homeseal LDS 100 vapour barrier film is also used as an effective moisture barrier in rooms with high humidity, such as bathrooms. It protects wall and ceiling partitions against the migration of water vapour, which could lead to mould growth or the degradation of insulation materials. When applied to internal walls or beneath plasterboard, it provides long-lasting protection for the building’s structure. Thanks to its flexibility and durability, the membrane works well with drywall systems. Using Homeseal LDS 100 as a vapour barrier in bathrooms helps maintain the correct indoor microclimate. This solution is recommended in modern residential construction, particularly in areas exposed to prolonged moisture.
