SBS (Styrene Butadiene Styrene) bituminous membranes are installed using a variety of methods, including:
- Heat welded seam method: involves heating the overlapped edges of the membrane with a propane torch to create a seamless, watertight bond between the two pieces of membrane.
- Cold adhesive method: involves using a cold-applied adhesive to bond the membrane to the roof deck.
- Mechanically fastened method: involves using special mechanical fasteners to attach the membrane to the roof deck.
- Ballasted method: involves placing heavy stones or pavers on top of the membrane to keep it in place, without the need for fasteners or adhesives.
The choice of installation method will depend on factors such as the type of roof deck, the local building codes and regulations, and the desired level of seam strength and durability. It is recommended to seek the guidance of a professional roofing contractor for the installation of an SBS bituminous membrane.
