Attic ventilators

You’re aware of the importance of ventilating the interior of your home. But do you know that it is also important to ventilate the attic? In fact, the National Building Code requires that this empty space be adequately ventilated.

Why should you ventilate the attic?
In wintertime, the difference in temperature between the attic space and the outside causes condensation and frost. Ice may even accumulate on the roof. As a result, the roof of your house could be damaged by water seepage. In summertime, this empty attic space attains undesirable extreme temperatures. All of these phenomena resulting from a lack of ventilation cause numerous harmful effects to your house’s structure.

THE solution
The attic must have an air inlet at the base (such as a soffit), as well as an air outlet located at the top of the roof (attic ventilator). The combination of the attic ventilator and the soffits creates a chimney-like effect that allows for proper ventilation of the attic.

Venmar technology, a trusted name
Venmar has developed a unique and patented attic ventilator. Commonly called a roof vent or powered roof ventilator, it provides better corrosion resistance thanks to its galvanized steel components, its baked polyester paint finish and its innovative design that prevents rain and snow infiltration. Its exclusive gutter evacuates the water created by condensation, thereby preventing the premature deterioration of materials. Finally, because it has a multi-slope base, the attic ventilator is easy to install, and the fine screen prevents any obstruction of the ventilator.
