Polymer Modified Bituminous Membrane Metal Roof System

Modified bitumen sbs roofing systems.

Polymer modified bituminous membrane metal roof system.

Get to know more about one of the most popular commercial roofing systems. Some sbs modified membranes are self adhering. App modified bitumen roofing materials are produced in factories and sold in sheets or rolls. Elastophene flam elastophene flam is an sbs modified bitumen base ply for use in approved multi ply membrane and flashing assemblies.

Modified bitumen is a type of asphalt product that can be applied in a number of ways to the roof in both hot and cold temperatures. The sheets themselves are inherently waterproof. Sbs polymer modified bitumen membranes commonly are installed in hot moppings of asphalt similar to bur systems or cold adhesive. Since the mid 70s.

The two main polymer modified bitumen membranes on the market are sbs and app membranes. The use of polymers mixed with the coating bitumen improves flexibility toughness and low temperature properties. There are two main types of bituminous roof systems built up roofing bur and multi ply polymer modified bitumen. A standard mbs roof system should have a base sheet or ply similar to the bur system then a waterproofing sheet similar to single ply.

Modified bitumen roofing is generally low maintenance and can last for decades. The variety of single ply roofing membrane adhesives available gives contractors some flexibility in their choice of material. Polymer modified roof membranes have been in use in the u s.

Modified bitumen roofs have a lot of advantages over other types of membrane roofing and are often seen as the modern alternative to the built up roof. Sealing and repairing building cracks roofs sheet metal work bituminous felts and other types of roofing sheet membranes. Sika also has self adhesive polymer modified bituminous sealing tapes which are laminated with aluminum foil on the upper side and contain no reinforcement.

Manufactured app membranes also contain an insulating layer for a more energy efficient roof. That is they contain an adhesive backing. A major advantage of mb systems over bur is that they generally use fewer layers and are therefore less labor and material intensive. Built up roofing bur bur systems have been used for more than 100 years in the united states.

App polymer modified bitumen membranes typically are heat welded or torch applied. But how do you. Elastophene flam is composed of a proprietary formulation of elastomeric styrene butadiene styrene sbs polymer modified.
