Ventilation

A Word On Ventilation

Whenever you properly air-seal and insulate a building (either new construction or retrofit), you must develop a ventilation strategy.  Anyone who advises otherwise doesn’t fully understand the principles of cold-weather building.

When it comes to buildings, you can have it one of two ways:

1. Build a conventional structure that “breathes.” These buildings may have insulation, but they are literally designed to allow air to pass freely through their walls and roof. When the weather is calm, you may retain some heat, but the air inside will quickly become stale. When the wind is blowing, you will lose heat rapidly, but you’ll feel fresh air in the form of cold drafts.

2. Insulate and seal your building properly. By sealing your structure, you not only gain control over the indoor temperature, you also gain control of your indoor air quality. A proper ventilation system will filter outside pollutants (including allergens) while preserving the heat inside. The result? You can cut your heating bill in half, while enjoying fresh air year round.

We spend 90 percent of our time indoors. But the air inside of our homes, schools and businesses is usually several times—and up to 100 times—more polluted than the air outdoors. It’s not surprising that the American Lung Association and the Maine Interior Air Quality Council recommend ventilators in every business and home, especially where children and elderly residents live. 

Several northern states (including Vermont and Minnesota) already have require ventilators as part of their building codes. To learn more information about air quality, visit:
