The OMG OlyVent is 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 breathers, the OMG OlyVent offers many unique features for better performance and design.
- The one-way OlyVent features a Duro Nitrile rubber valve, allowing trapped air pressure to escape, which helps to reduce blistering of the roof system and damage to roof insulation and the roof structure. The two-way breather, combined with the one-way vent, helps reduce moisture.
- Made from heavy gauge, spun aluminum for strength and durability.
- The conical shape and broad base opening allow for greater performance than standard, cylindrical designed vents, allowing for easier installation and a better-performing flashing detail.
- A simple identification feature distinguishes the one-way vent from the two-way breather, allowing roof inspections to be completed quickly and thoroughly.
- The vandal-proof cap design provides security while preventing the entry of wind-blown rain or snow.
- The versatile, one-way vent and two-way breather can be used with single-ply or BUR applications.
