Designed to withstand up to six months of outdoor exposure, the TESCON VANA tape from Pro Clima is an all-round adhesive tape that can cope with even the harshest weather conditions. Measuring 60mm by 30m long, this roll is ideal for creating airtight bonds with roof-mounted vapour check, sarking boards, wall-lining membrane and more. It's backed with special PP fleece so it tears off with ease and the release film is a simple-to-use siliconised paper. Turn to Tescon's Primer RP if you're dealing with subsurfaces with an insufficient load-bearing capacity.
