OPTI-iM412-B
4 Wings Roof Attic Vent with Insulated Base and Square Boot Flashing for Single-ply Roof (TPO or PVC)
The OPTI-iM112-B attic vent is designed for single-ply roofs and comes with a TPO or PVC boot flashing (see manufacturesr below) to weld to the roof for better waterproofing.The fin design and openings of the vent allow for optimal ventilation of the attic. The inside of the base is insulated, which prevents the risk of condensation. The ventilation power of this vent depends on several factors, including space in the attic and soffits being present or not. Under ideal conditions this vent has the capacity to ventilate from 100 to 350 sq. ft. It is always recommended to place a retention tray on the insulation under the vent.

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.
