Hydrokinetic metallic roof assemblies are designed to get rid of water. These systems are designed for steep slope apps. Steep sloped apps are located on household and professional programs exactly where drinking water can not continue to be to the roof system.
Styrene-Ethylene-Butylene-Styrene (SEBS): SEBS polymer is blended with asphalt inside a manufacturing facility. The SEBS modified asphalt is then reheated at The task web site in specially designed tankers or kettles. The new modified asphalt is applied inside of a fashion that is definitely nearly just like BUR.
The membrane is usually surfaced with mixture. SEBS modified mopping asphalt is extremely high priced and as a consequence not generally made use of. SEBS can be utilized to adhere MB sheets and not compromise efficiency in comparison to typical asphalt.
