Like humans and animals, your home’s attic needs to breathe to stay healthy. The mechanics of breathing for your home, however, are very different. 

In the winter, rising hot air inside your home can cause condensation to accumulate when it cools upon contacting your attic’s interior. This in turn can lead to mould, mildew and other airborne pollutants piling up indoors, causing health concerns. This condensation can also cause ice dams to form, leading to the potential for water damage to your roof shingles and to the inside of your home. During the summer months, a home without adequate airflow will trap hot air inside, leading to expensive air conditioning costs. 

To address these problems, buildings rely on two main methods to inhale and exhale – passive and active ventilation.

Passive ventilation

Most homes in Canada breathe through passive ventilation alone. This system uses roof vents that do not have any motorized or mechanical parts. Instead, it is the differences in air density between your home’s interior and exterior that causes air to flow in and out of these vents. 

Though relying on passive ventilation alone is enough to satisfy the minimum requirements of most building codes, the amount of ventilation your home gets can vary. Changes in indoor and outdoor temperature, wind speed, the amount of moisture in the air and even the design of your roof can affect whether your home gets enough airflow to ward off potential health concerns and water damage. To ensure your attic is breathing as well as it can be, you may wish to consider adding active ventilation systems.

Active ventilation 

Unlike passive roof vents, active ventilation uses a motorized fan to force air in and out of your attic. This ensures that your home is always breathing consistently, regardless of what conditions are like inside or outside. These kinds of vents are self-regulating and will turn on when passive roof vents need an extra boost. They will shut off automatically at times when passive roof vents have achieved enough airflow on their own. 

Due to their motorized design, active vents need energy to function, but that doesn’t mean you will be stuck with hefty electricity bills. Solar powered active vents, like the kinds produced by International Solar Solutions, provide homeowners with a cost-effective and environmentally-friendly solution for active ventilation.  

Active vents are also incredibly versatile. As we’ve covered before, they can be used to ventilate a large array of buildings, including storage sheds, modular outdoor offices and even portable toilets.

Whether active or passive, International Solar Solutions has options to ensure your home is breathing clean air

We now offer the SNOWVENTCO smart vent cover, featuring a built-in stainless steel micropore filter that guarantees only clean air enters your home. Homeowners can choose to have this cover installed over passive vents, or to have it fitted over our iSolar 19W-MOD-SNV solar-powered fan for active ventilation. Its clog-free design exceeds industry standards for airflow, while the hail-resistant pleated filter keeps out 99 per cent of unwanted elements, including snow, rain, animals, moisture and mould. The filter is also self-cleaning, using the outflow of warm air from the attic for this purpose.
