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.
Colours shown above may not appear exactly as intended due to monitor settings on your computer.
|The requirements are 1/150 (Section 9.19.1 of the Canadian Building code of Canada).|
|The base flashing of this model was designed to be incorporated within the roof membrane (Torch-down Roll) and does not require a curb box. The neck of the ventilator is insulated to prevent condensation.|
|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.|
