OPTI-FC412 – Ridge vent for cathedral roof

This Cathedral-type roof vent exchanges the air from the attic with the combination of a 3-or 4-fin vent. It is the ideal system for preventing heat and moisture accumulation in the attic that damages the structural integrity of the building and its components. By exchanging air from the space between each roof truss with the air coming from the soffit, the stale air will be directed towards the vent and the introduction of fresh air will maintain the ideal temperature for the attic. There will be an uninterrupted exchange of air. There will be an exchange of air in the attic at a frequency of 418 ft ³/min, thus ventilating an area of 1000 to 1200 sq. ft.

Use

Ventilation is required by the Canadian Building Code. So a Good ventilation means keeping the attic space near the outside temperature to avoid excessive contrasts. With the help of soffits, for example In summer, the chimney effect created by the Optimum ventilator eliminates excess heat from the attic and thus helps maintain the integrity of the asphalt shingles. In winter, you will get a drier attic. So no matter what the season, Optimum Ventilators will help to optimize the comfort of your home!

Tightness of the roof or parts installed by the contractor are not guaranteed as they are out of the control of the manufacturer. It is the roofer’s responsibility to ensure that the base is properly waterproofed using the proper roofing products. The Association of Master Roofers (AMCQ) recommends using the following technique: Metal flanges: The metal flanges of all projections must be coated with a primer embedded in plastic roofing cement, covered with a fold of cotton saturated with asphalt or canvas, followed by a fold of 15-pound felt and another fold of cotton saturated with asphalt or canvas embedded in a bitumen. In addition, having no precise notion of the composition of the building such as the tightness of the vapor barrier, the insulation or the exact amount of air inlets; these elements do not allow us to give a guarantee on the final result. Proof of purchase showing the date, your name and the shipping address will be essential in order to make any warranty claim.
