Adhesives and Cements

With over three decades of experience producing modified bitumen, we understand the science of formulating systems that last.

Our SBS is a premium modified bitumen engineered specifically for elasticity. It is made to withstand even the harshest environments.

SBS is the most customizable of our low-slow commercial roofing products with glass, polyester and composite reinforcements. It can be installed with the widest variety of application methods including cold applied, heat weld, self-adhered, mechanically fastened, and hot applied applications.
