Harness the Wind
The Dow Vented Roof System (VRS) combines a TIEMPO™+ 2000 TPO roofing membrane with an air-sealed assembly and release vent technology. This creates a system that neutralizes the power of the wind and keeps the membrane tightly secured to a monolithic deck or air barrier over steel or wood – all without the need for (and added cost of) fasteners, stone ballast, pavers or adhesives in the field of the roof
