They were designed to reduce labor requirements for installation and have become increasingly popular over bur system applications.
Torch applied roof membrane.
The workhorse paradiene 20 tg base ply absorbs roof stresses while the granule surfaced top ply paradiene 30 tg shields the base from the elements and mechanical abuse.
This installation process gives torch down roofing a uniquely watertight seal making it a great choice wherever water damage is a serious concern.
In a two layer torch down roof the system is complete at this point.
When the two layers are pressed together they form a seal.
App atactic polypropylene uses plastic type modifiers not rubber.
Torch down roofing consists of multiple modified bitumen membranes applied with a propane torch.
The top membrane sheet to a torch down roofing system is a smooth cap sheet.
Demonstrating how torch applied modified bitumen felt membranes are installed along with high performance insulation to create a warm roof construction.
Paradiene 20 tg 30 tg is a multi ply system.
Atactic polypropylene app is heat torch applied modified bitumen membrane that provides a greater re cover system uv resistance and increased durability for roofs with high traffic movement.
