Varibel steam brake - Effective humidity and vapour control

Designed to be used on the warm side of the wall or roof structure, the Varibel vapour barrier acts as an effective vapour barrier. The membrane is made of polyester and helps to maintain a good airtightness of the building structure. The unique property of the vapour barrier to allow bi-directional vapour transport means that it can handle vapour flow both outwards and inwards, promoting the drying out process and reducing the risk of potentially damaging condensation and moisture accumulation. The product is an essential component in modern construction projects where moisture and water vapour control is critical to maintaining high build quality and a sustainable indoor climate.
