Self Adhesive Vapour Barrier

A self adhesive vapour barrier is a sheet, usually polyethylene, used for damp proofing to prevent the build up of condensation in various building assemblies.

These highly effective vapour barriers consist of a reinforced aluminium composite that’s self adhesive on the reverse and protected by a detachable film.

The Benefits of Self Adhesive Vapour Barriers

Simplified Installation - The self adhesive backing eliminates the need for tapes, glues, or mechanical fasteners, streamlining the installation process and saving you time and labour costs.

Enhanced Airtightness - The self adhesion creates a strong, continuous bond to the substrate, minimising air gaps and leaks that could compromise the vapour barrier's effectiveness.

Superior Moisture Protection - Self adhesive vapour barriers are constructed from high quality materials that offer exceptional resistance to moisture transmission.

Improved Durability - These barriers are built to withstand the rigours of construction and offer long-lasting performance.

Self Adhesive Vapour Barrier Brands

Our ALUTRIX® self adhesive vapour barrier membranes are designed for use in a wide range of construction applications.

The membranes are suitable for use in the following areas; beneath mechanically fixed single ply roofing membranes, on self adhesive membranes, felt, asphalt or other liquid waterproofing systems, and profiled metal sheeting and standing seam systems.

Applications for Self Adhesive Vapour Barriers

Self adhesive vapour barriers are a versatile solution for a variety of applications, including:

  • Flat roofs (ideal for large commercial buildings)

  • Walls (particularly in high-humidity areas like bathrooms and kitchens)

  • Ceilings (especially below unconditioned spaces)

  • Basements

Choosing the Right Self Adhesive Vapour Barrier

When selecting a self adhesive vapour barrier, consider factors like:

Material - Common materials include aluminium foil laminates, polyethylene films, and composite membranes. Each offers unique properties to suit specific applications.

Permeability Rating - The perm rating indicates the rate at which moisture vapour can pass through the material. Choose a barrier with a low perm rating for maximum protection.

Size and Roll Length - Select a roll size that accommodates your project dimensions and minimises waste.

By incorporating self adhesive vapour barriers into your construction project, you'll ensure a moisture controlled environment, promoting better building performance and occupant comfort.
