IKO AquaBarrier AVB Air & Vapour Barrier is a self-adhering, non-permeable membrane providing superior performance in wall assemblies where an air and vapour barrier is required. AquaBarrier AVB is manufactured by integrally bonding SBS modified asphalt to a high density, cross-laminated woven polyethylene film. The backing surface is an easily removed silicone release paper. AquaBarrier AVB membranes are available in both standard and low temperature grades in a variety of roll sizes and can be applied to all common substrates such as gypsum, OSB, concrete, CMU and plywood. AquaBarrier AVB provides an effective barrier to moisture vapour transmission and air leakage when installed according to IKO specifications and used with S.A.M. or S.A.M. LVC Adhesive. Application temperature for AVB Low Temp must be between ‑10°C to 10°C (14°F to 50°F). The IKO AquaBarrier line is designed for numerous applications such as masonry cavity walls, metal cladding systems, curtain walls and parapets and also includes tape and mastic products for specialized detail areas.
