Roof Drains / OlyVents

OMG OlyVents are engineered to prolong the life of the roof system by reducing moisture within the roof system and trapped air pressure within the building. The one-way vent allows trapped air pressure to escape while the two-way breather, combined with the one-way vent, will help reduce moisture. Trapped air pressure and moisture can cause a reduction in thermal protection of the insulation and roof membrane system leading to roof deck damage. Available as either one-way vents or two-way...
