VacuSeal vent-secured roofing system uses special vents said to harness wind power to lock roof membranes in place. The system reportedly provides optimal performance while maximizing opportunities for retrofit and monolithic deck applications. Negative pressure venting pulls air and moisture from under the membrane to maintain insulation dryness and R-value. There are no cold-weather limitations for installation, no VOCs, and no odor. The system’s V2T vents are mad from UV-resistant PVC, contain no moving parts, require no penetrations, and provide performance regardless of wind direction. The product is UL certified with uplift certification at 195 psf negative pressure.
