Flat Roof Ventilator Model #101

The ventilator functions with the combination of wind and pressure differentials, thus creating a vacuum like effect, removing moisture and stale air from within the attic space.

Building code requires ventilation for restricted air space or flat roofs regardless of air intake. The requirements are 1/150 (Section 9.19.1 of the Canadian Building Code of Canada)	Available in these standard colours: Black   Brown   Grey   Colours shown above may not appear exactly as intended due to monitor settings on your computer.
This model is design to be installed onto a wooden curb.
This model can easily replace two to three conventional gooseneck vents.
The air space between the underside of the roof deck and the insulation determines the area it can ventilate.
Standard colours: brown, black or grey. A limited selection of special colours is available at a slight premium. Click here to view your special colour options

N.B. The opening (hole) of the wooden curb determines the Net Free Ventilation Area and not the ventilator.

When specifying the size of the ventilator, remember to make an allowance for the thickness of the wooden curb as well as the roof membrane.
