Where Termination Bars Are Used
Termination bars are installed where a roof membraneMaterial - A single-ply membrane is a roof covering that uses one continuous layer of material to waterproof low-slope roofs. More transitions at a wall, parapet, curb, or other vertical surface and cannot wrap over the top. The bar is fastened through the membrane into the vertical surface, securing it in place, and a bead of sealant is applied along the top edge to prevent water from entering behind it.
Because the membrane stops at this point, it relies on mechanical attachment and sealant rather than membrane coverage to prevent water infiltration. As sealants or fasteners fail over time, water can work behind the membrane and lead to leaks at the roof-to-wall transition.
