ALUTRIX® self-adhesive vapour barriers are used in a wide variety of applications in the building industry. Suitable for all internal conditions, including very high humidity. Consists of a reinforced composite aluminium foil with a tenacious self-adhesive backing and removable release film. ALUTRIX® vapour barriers are quick to install and they create an airtight and vapour-tight seal.

Offers very high vapour resistance which is sufficient to accommodate extreme internal conditions such as buildings containing wet industrial processes, breweries, swimming pools, sports halls, kitchens and bathrooms etc.
