Attic Ventilation
Attic ventilation works on the principle that heated air naturally rises, primarily utilizing two types of vents:
- Intake vents, located at the lowest part of the roof under the eaves, allow cool air to enter the attic.
- Hot air exhaust vents, located at the peak of the roof, allow hot air to escape.
Taking advantage of this natural process, referred to as passive ventilation, is the most common way to vent an attic. In order to facilitate this exchange of warm and cool air, the general rule of thumb suggests installing at least 1 sq. ft. of vent for every 300 sq. ft. of attic floor, this all depends on the local building codes.
An improperly ventilated attic can cause moisture to be trapped which in turn can cause mold and potential damage to your attic system.
Attic Insulation
More than 90 percent of homes in North America lack adequate attic insulation. Many homes in Canada lack adequate insulation, costing homeowners more money on energy bills to keep their houses warmer in the winter and cooler in the summer. With proper insulation, you can save money and be more efficient with your energy — and you can start by properly insulating your attic.
If your attic is completely un-insulated, we’ll help you start from scratch. If your attic just needs a top up for maximum efficiency, we’ll help you there as well.
