Polymer Modified Bituminous Membrane Metal Roof System

There are two main types of bituminous roof systems built up roofing bur and multi ply polymer modified bitumen.

Polymer modified bituminous membrane metal roof system.

Polymer modified roof membranes have been in use in the u s. 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. That is they contain an adhesive backing. Sealing and repairing building cracks roofs sheet metal work bituminous felts and other types of roofing sheet membranes.

Sbs polymer modified bitumen membranes commonly are installed in hot moppings of asphalt similar to bur systems or cold adhesive. App polymer modified bitumen membranes typically are heat welded or torch applied.

But how do you. Sika also has self adhesive polymer modified bituminous sealing tapes which are laminated with aluminum foil on the upper side and contain no reinforcement. 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.

Some sbs modified membranes are self adhering. There are two types of mb roofing membranes. Since the mid 70s. Built up roofing bur bur systems have been used for more than 100 years in the united states.

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. A major advantage of mb systems over bur is that they generally use fewer layers and are therefore less labor and material intensive. Learn about modified bitumen app roofing systems. Modified bitumen sbs roofing systems.

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. Manufactured app membranes also contain an insulating layer for a more energy efficient roof. Elastophene flam elastophene flam is an sbs modified bitumen base ply for use in approved multi ply membrane and flashing assemblies. App modified bitumen roofing materials are produced in factories and sold in sheets or rolls.

Get to know more about one of the most popular commercial roofing systems. Elastophene flam is composed of a proprietary formulation of elastomeric styrene butadiene styrene sbs polymer modified. A modified bitumen membrane mbs roof is a system developed by taking the qualities of a bur system along with the qualities of a single ply roof.
