Within the walls of timber frame constructions or where vapour control is needed: Novia 500G 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 500G AVCL?

Novia 500G AVCL (Air and Vapour Control Layer) is a high-performance, reinforced polyethylene membrane designed to control the passage of air and vapour in building structures. It helps prevent air leakage and moisture buildup, enhancing energy efficiency and protecting insulation in walls, roofs, and floors.

What are the key features of Novia 500G AVCL?

Novia 500G AVCL is highly durable due to its reinforcement, offering excellent air and vapour control. It is easy to install and is suitable for use in a range of applications, including residential and commercial buildings. The membrane helps reduce condensation, improves airtightness, and increases the overall energy efficiency of a structure.

How do I install Novia 500G AVCL?

To install Novia 500G AVCL, ensure surfaces are clean and dry. Unroll the membrane and fix it to the building frame or surface using appropriate fixings, such as staples or battens. Overlap the joints by at least 100mm and seal all overlaps and penetrations with Novia sealing tape to ensure an airtight installation.

Can Novia 500G AVCL be used in both walls and roofs?

Yes, Novia 500G AVCL is versatile and can be used in both wall and roof applications. Its high performance in controlling air and vapour movement makes it suitable for use in multiple parts of the building envelope.
