ELT-Pefoil 200 Building Polyethylene Vapor Barrier 3x45m, 135m2

UV stabilized 200 micron thick polyethylene film. Used as vapor insulation for walls and roofs. Material is stabilized against natural aging and UV radiation. Overlaps of 10cm-15cm should be glued or welded. Recommended adhesive tape is Tyvek Butil tape. Country of origin: EU. Vapor barrier films or vapor barriers are the simplest and most commonly used construction films. They do not allow water vapor to pass through in either direction (outside - inside or vice versa) and are considered "non-breathable" films.

However, this insulation provides protection against moisture, protecting both the insulation material itself and the building structure. Vapor insulation is used for roof, wall, and floor insulation.

The range of these films on the market is very wide, and the quality of the products varies, so when choosing a vapor insulation film, several conditions must be observed. The external vapor insulation film looks like a regular film, but this is a deceptive impression. According to European Union (EU) and Latvian building regulations, the film must be at least 0.2 mm or 200 microns thick. It must be made of primary polyethylene (polypropylene) rather than with secondary polyethylene additives, as is often the case with many of the offered vapor insulation films. This can be noticed "by eye" - if the film has secondary polyethylene additives, sand grains, dirt, etc. will be visible, which will reduce the quality of the film during operation.

A high-quality vapor insulation film must be UV stable. During the production process, a special chemical additive is added to the mass from which the film is made, which stabilizes the polyethylene molecules and extends the lifespan of the film. High-quality vapor insulation films are colorless or have a light, clear color (e.g. blue) rather than pigmented. The film material must be supplemented with a UV stabilizer.
