Exhaust Vents

This CSA approved 50 square inch NFA, type B static roof exhaust vent is designed for use on attics, with installation near the peak of the roof. It is snowproof, effective at diverting water, and allows for airflow to keep attics cool and dry. Constructed with a heavy-duty ¼ inch thick polypropylene shell and 304 grade stainless steel filter, it provides a no-clog, 99.99% impenetrable barrier to snow, rain, and other elements. Suitable for use on sloped roofs, it can be used as a house or shed vent. For best results, it should be placed over a 7 ¼ inch by 7 ¼ inch square hole or 8 inch round hole. Note: The vent hood should be installed in one piece and is not designed to come apart from the base, please check local building codes before installation.

This Type B, box style (50 sq inch flow) Roofers' INTAKE vent is for use on sloped roofs but may be installed LOWER on the roof (install according to local building codes) and used as an air intake vent. Based on the original Roofers' Exhaust Vent design, this INTAKE vent incorporates a built in heavy water deflector. Air steadily moves through the vent into the attic replacing rising warm/moist air.....while blowing snow/rain is kept outside. CSA approved and third-party tested indicating that the Roofers’ Vent provides 99.99% blockage of airborne elements—even at 175kph/110mph windspeeds.
