IKO AquaBarrier TG 0.5 m and 1 m Air and Vapour Barriers are used in wall membrane assemblies and waterproofing applications, with proven results of air/vapour resistance. AquaBarrier TG is manufactured from an inorganic reinforcing mat of high strength non-woven glass fibers that is coated with select SBS polymers and premium asphalt. The product can be applied to a variety of substrates such as concrete, gypsum and CMU. When installed according to specifications and used with IKO Spray or Mod Bit primers, AquaBarrier TG provides an effective barrier to moisture vapour transmission and air leakage. Micro-perforated film is bonded to both sides of AquaBarrier TG, on the top side to provide superior lap adhesion and on the heat welded side, where it completely disappears during installation.
