- The Situra FlamLINE Expansion Joint is manufactured from a proprietary co-polymer with polyester reinforcement for thermal stability. The product's manufacturing permits 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. FlamLINE is compatible with torch-applied asphaltic and self-adhered membrane. All detailing is factory manufactured to suit site specific requirements.

All seaming is a proprietary vulcanization process, which results in monolithic and elastic seams.
