Vapour control layers are important for the performance of a liquid applied roofing system. Designed to help manage moisture within the roof build-up, vapour control layers reduce the risk of condensation and contribute to the long-term effectiveness of the insulation and waterproofing system. Sika's vapour control layers are designed to seamlessly integrate within liquid applied waterproofing systems as part of a complete system.
