If your home has big windows, this past summer’s scorching heat likely took its toll on both your body and your electrical bill. As the cooling fall weather sets in, now’s the perfect time to get ahead of next summer’s heat by installing a solar attic fan.
In recent years, large floor-to-ceiling windows have become a trend in many North American homes. Sleek and aesthetically pleasing, large windows are prized for the high amount of natural light they let into a building. However, big windows also mean big heat. Their expansive planes let in large amounts of heat on hot days and trap it indoors.
Worse, most large panes of glass are not built to open like smaller windows. This blocks airflow in the home, compounding heat buildup. And during heat waves like the ones we saw a few months ago, this massive buildup of heat forces your air conditioning to work extra hard.
Of course, replacing large windows with energy efficient models is a possible solution. But this often requires substantial investments of time and money. Fortunately, there’s an easy and cost effective way to keep your big windows, while cutting high electrical bills down to size.
Solar attic fans let you keep your big windows, without big heat
At iSolar Solutions, we’re proud to offer one of the fastest and most cost effective ways to tame the heat that big windows let in.
The solar attic fans in our bestselling FLEX line are the only retrofit-ready models on the market. Since they fit into the existing vents of most homes, this easy installation means they can start ventilating and cooling your home in less than 15 minutes!
Normally, hot air indoors rises and builds up in the attic. Passive vents then use differences in indoor and outdoor air pressure to circulate that hot air out. However, these vents don’t have mechanical parts, and often struggle to achieve adequate airflow. For proper ventilation, an attic must cycle out all the hot, humid attic air at least 6-10 times an hour. While they meet local building code requirements, these passive vents are just not up to the task!
Solar attic fans solve this by automatically switching on to increase ventilation when the sun starts to shine, when your attic needs to rid itself of that hot stale air. They give your home’s natural airflow a much needed boost, offsetting much of the heat that large windows let in. Studies have shown solar attic fans can lower indoor temperatures by up to 30°F (16°C). This cuts reliance on air conditioning by as much as six per cent. Also, there is the added benefit of cutting wear and tear on the AC unit itself.
Powered solely by the sun, all of this is achieved without adding any costs to your summer electrical bills.
Winter is coming. Is there still time to install one?
Yes! The mild fall weather is a perfect time to prepare your home for the heat of next summer. Our solar attic fans lack complicated wiring, so you don’t need to hire an electrician. Roofers and contractors can handle the job.
If you’re a DIYer, you can even install one yourself in less time than it takes to get an oil change for your car. Simply download the instructions on our website! Another option is ournetwork of trusted installers. These professionals are trained in all our products and thoroughly understand the science of proper ventilation.
Our solar attic fans are also modular. This allows for custom configurations if structural architecture or shade are challenges for installation.
You can purchase all of iSolar Solutions’ fansdirectly through our website. Finding the right model for your home is also a breeze – we offer a handy product configurator that helps you pick and choose.
