Fortex REFLEX (Vapor Barrier Alu) Reinforced foil with aluminum layer 1.5x50m, 75m2

Armored film with aluminum layer. The material is used as a vapor insulation barrier with a heat reflecting layer for walls and roofs. It is recommended to use adhesive tape for joining the seams of the material. It is used as a vapor insulation for walls and roofs with a heat reflecting effect. The material is covered with an aluminum layer on the inside of the room, creating 10-15 cm overlaps. The overlaps are glued together. Recommended adhesive tape - Juta Butyl tape.

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 considered. The external vapor insulation film looks like a regular film, but it 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, impurities, etc. will be visible, which will reduce the quality of the film during operation.

A high-quality vapor insulation film must be resistant to ultraviolet radiation. 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 prolongs the lifespan of the film. High-quality vapor insulation films are colorless or have a light, transparent color (e.g., blue) rather than pigmented. The film material must be supplemented with a UV stabilizer.
