Our external wall insulation (EWI) build-ups showcase the different system configurations available for a range of substrates, performance requirements and aesthetic preferences. Each build-up illustrates the layers and compatible products used, from adhesives and base coats to insulation and decorative finishes. Sika offers EWI systems featuring platinum insulation boards, rockwool insulation, phenolic insulation and insulated concrete solutions, all of which are designed to improve thermal performance, enhance facade appearance and ensure long term durability.
