MIDLAND, Mich. -- Dow Roofing Systems LLC, (DRS) will cease the sale of TPO (thermoplastic polyolefin) and PVC (polyvinyl chloride) roofing membranes and accessories in North America, effective January 31, 2011.

Dow Building Solutions strategy is to focus on its market leading insulation and adhesive solutions along with ongoing development of differentiated roofing innovations for the future.
