Description

Vapour control layers (VCLs) are essential for regulating the flow of water vapour in insulated buildings. Without these membranes, condensation can wreak havoc on the building structure, leading to long-term damage and increased heating and cooling expenses. Even a mere 3% moisture deposited within the insulation can reduce its performance by up to a third.

This Novia 1000 VCL not only manages moisture within your structure but also acts as an effective barrier against air leakage, preventing unwanted convection flows. To ensure a complete durable vapour seal, this Novia 1000 VCL should be used in conjunction with Novia's compatible butyl and foil sealing tapes throughout its lifespan. For a fully airtight and vapour-resistant system, it should be combined with Novia's breather membranes.

In terms of application, Novia VCL products are easily sealed using Novia's double-side butyl tapes, typically with a 75mm to 100mm overlap. However, some products may require a larger overlap for optimal performance. To reinforce the seal, a lap seal is applied on top using Novia's reliable foil tapes. For stronger tapes, choose wider tapes that align with your specific application and budget. To enhance overall airtightness, pre-applying butyl tape to studs or timbers at the fixing points is recommended. This preparation ensures a superior seal when applying staples or any final wall coverings like plasterboard.
