What is it?

Polymer-modified bitumen or modified bitumen (MB) sheet membranes are composed of reinforcing fabrics that serve as carriers for the hot polymer-modified bitumen as it is manufactured into a roll material. MB roof system membranes are composed of multiple layers, much like BUR membranes. MB roof systems typically are installed as a two-ply system and almost always are fully adhered.
A roof system composed of a built-up roof membrane with two plies or three plies and a polymer-modified bitumen membrane cap sheet is commonly referred to as a ‘hybrid’ system.
