A termination bar is a metal strip used in roofing and construction to secure and seal the edges of various roofing materials. It is made of aluminum, with a width of 1 inches and a thickness of 1/8 inches.

Termination bars are commonly used with roofing membranes, such as PVC or TPO, to secure the edges of the membrane to the roof's perimeter, walls, or other structures. The bar is installed by screwing or nailing it onto the roof substrate or a suitable mounting surface, such as a parapet wall. The roofing material is then folded over the termination bar, creating a tight seal that prevents moisture and debris from penetrating underneath the membrane.

Termination bars are an essential component of roofing systems, as they help to ensure the longevity and durability of the roof. They are easy to install and are available in various lengths to accommodate different roofing applications. Additionally, they can be painted or coated to match the color of the roofing material, providing a seamless and aesthetically pleasing finish.
