These vents are perfect for rooftops and can be constructed with Galvanized Steel, Galvalume steel or aluminum. We also offer both manual and mechanical operation for these vents as well. Various designs allow for high volume, low volume or low profile depending on your building size and requirements.

Ridge Vent (low profile)

Construction: Each unit is factory assembled and ready for installation. Each vent features the Cor-A-Vent® ventilation core, a time-tested, economical, self-cleaning and durable core which has been in service since 1970. Steel parts are constructed with 24 gaugeGalvanized or Galvalume™

Design: The unit’s aerodynamic, low-profile design enhances the looks and performance of architectural roof systems. The unit moves toward the ridge on floating roofs and is fabricated to match your roof’s slope.

Ridge Vent (low volume)

Construction: Our low volume ridge vents are constructed of a 26 ga. steel exterior shell combined with internal components of 24, 20 and 18 gauge die formed sheet metal and machined parts.

Design: The low volume ridge vents are aerodynamically proportioned to exclude weather, and protect air passages and full outlet areas. They feature a continuous slot on the bottom of both sides of the windbands allows for drainage. They can accommodate up to 6:12 roof pitch and are fully protected by a 4×4 mesh galvanized hardware cloth bird screen. The vent also features an operable damper that opens to any degree, from full open to fully closed, with a pull chain operator.

Ridge Vent (high volume)

A high volume ridge vent is a natural ventilation system that provides a natural intake of fresh supply air and a natural evacuation point for hot air and fumes. Warm air naturally rises to the ceiling, natural ventilation lets it escape. This system has zero operating cost, zero maintenance costs and makes for a cooler and more comfortable facility.
