Novia Polythene Vapour Control Layer DIY Kit 1000 Gauge – 100m2

For application as a vapour control layer in walls of timber frame constructions or situations that necessitate the regulation of water vapour passage, Novia 1000 VCL is made of medium specification, virgin-grade blown polythene material. With a green tint, the 1000G polythene retains its full CE approval as a vapour control layer.

This 100m² DIY kit consists of one 4m x 25m 1000 gauge Vapour Control Layer, two 30m x 30mm butyl tapes and one 45m x 75mm foil tape. It is cheaper overall than paying for the individual items combined and Novia AirSeal310 Sealant 310ml. Not only is it more convenient, but it ensures you order the adequate number of tapes as well as the correct types for your vapour control layers.

Vapour Control Layers (VCLs) are designed to be installed on the interior (warm side) of insulated buildings in order to regulate the movement of water vapour, which naturally forms due to normal building usage. When constructions lack these membranes, condensation is likely to form within the building structure. This condensation can potentially cause long-term damage to the building and result in substantially higher heating and cooling expenses in the short term. Even a small amount of moisture, as little as 3% deposited within the building’s insulation, has been proven to hinder insulation performance by up to one third.

In addition to managing water vapour, this product also serves as a barrier against air leakage, preventing energy losses caused by undesired convection currents. To ensure a complete vapour seal throughout the entire lifespan of the product, Novia compatible butyl and foil sealing tapes are advised. For an airtight and vapour-resistant system, Novia 1000 VCL is best used in conjunction with Novia breather membranes.

Application

• Novia VCL products are secured using double-sided butyl tapes with a 75mm to 100mm overlap. Larger overlaps may be necessary for specific products. A lap-seal is then applied using Novia foil tapes. Choosing a wider tape strengthens the seal, so base your choice on application and budget. To improve airtightness, pre-apply butyl tape to the studs or timbers where fixings will be placed. This significantly improves the resulting seal when using staples or other fasteners on the membrane or final wall covering like plasterboard.
