Air Leaks

When areas of your office are not properly sealed, outside air can leak in to your building causing reduced comfort. Additionally, outside air mixes with air from heating and cooling systems, which contributes to large amounts of energy waste. A quick and easy solution to prevent such air leaks is to add weatherstripping and air sealing to windows and doors. This is cost-effective and will reduce your office's electric bills. Below you will see methods that will help you identify and seal these leaks with appropriate materials.

What can you do about it?

Weatherstrip and caulk around all entrance doors and windows.

Weatherstripping and caulking limit air leaks that could account for 15% to 30% of heating and cooling energy requirements.

Seal air leaks.

Use caulk, foam spray, and weather-stripping around electrical outlets, cable and other wiring.

Air Sealing vs. Insulation

Insulation is like a fuzzy wool sweater on a winter day. It will certainly keep you warm if the air is calm. But if the wind picks up, you are going to need a windbreaker to keep the breeze from carrying away the heat. Air sealing is like adding the windbreaker. It keeps the conditioned air where it belongs.
