Within the walls of timber frame constructions or where vapour control is needed: Novia 1000G AVCL (Air and Vapour Control Layer) is good to use within the walls of timber frame constructions or where vapour control is needed because it effectively regulates the passage of water vapour through the building envelope. By providing a strong barrier against moisture, it prevents condensation from forming within the structure, protecting insulation and timber from potential dampness and damage. This control helps to maintain the thermal efficiency of the building and contributes to the long-term integrity of the construction.

What is Novia 1000G AVCL?

Novia 1000G AVCL is a heavy-duty, reinforced air and vapour control layer (AVCL) designed to control air and vapour movement in building structures. It provides excellent moisture control, reduces air leakage, and improves the overall energy efficiency of buildings by protecting the insulation in walls, roofs, and floors.

What are the key benefits of using Novia 1000G AVCL?

Novia 1000G AVCL offers superior air and vapour resistance, reducing the risk of condensation and improving the airtightness of buildings. Its durable, reinforced construction ensures long-lasting performance, making it ideal for use in high-demand residential and commercial projects.

What applications is Novia 1000G AVCL suitable for?

Novia 1000G AVCL is suitable for a variety of applications, including walls, roofs, and floors in both new build and retrofit projects. It is commonly used in timber-frame and masonry construction to create a continuous air and vapour barrier, preventing moisture-related issues.

How do I install Novia 1000G AVCL?

To install Novia 1000G AVCL, start by ensuring that the surfaces are clean and dry. Unroll the membrane and fix it to the building structure using staples, battens, or other suitable fixings. Overlap the edges by at least 100mm, and seal the overlaps and any penetrations using Novia sealing tape to maintain airtightness.
