Knauf Vapour Panels are specially designed to provide high vapour resistance. The moisture-resistant plasterboards have a metalised polyester foil lamination, which creates an effective vapour barrier to minimise moisture dispersion, making it perfect for lining the internal side of exterior walls, as well as the underside of roofs and decks. 

High-performing plasterboards are long-lasting products. The performance does not change over time. Knauf vapour panels do not support or promote the growth of fungi or moulds. They are easy to install and do not require any special tools for installation.
