Situra Inc., North Tonawanda, N.Y., offers the FlamLINE™ torchable waterproof expansion joint, used with torch-applied roofing and waterproofing membranes. The product is manufactured from a proprietary copolymer with polyester reinforcement. Its superior qualities allow for monolithic seam vulcanization, tri-directional movement and high fire resistance. The adhesion to the waterproofing membrane sheet is torch-welded. The torchable membrane is heated and the liquefied asphalt penetrates into the FlamLINE dimpled surface for a homogenous bond. The product is compatible with torchable asphaltic and coal tar pitch membranes, as well as peel and stick membrane.
