The VacuSeal Vent Secured Roofing System uses special vents that harness wind to lock roof membranes in place. Negative pressure venting pulls air and moisture out from under the membrane, keeping insulation dry and maintaining R-value.
No temperature limitations, VOCs or odors. Requires less glue, ballast and fasteners than other roofing systems. UL certified with uplift certification at 195 psf negative pressure.
