You get close to a window or exterior door of your home. Then you feel a cold draft, even though your furnace is running and the door or window is closed. That draft is a sign you need air sealing around your windows and doors. In today’s blog, Air Authority explains how to seal windows and doors to make your furnace more cost-effective while keeping you and your family comfortable.
Weatherstripping is the easiest and least expensive way to seal doors and windows from the cold. You can find weatherstripping at your local hardware store. This is adhesive-backed foam, felt, or other soft material that comes in long strips that you can install between a door and the side door jamb. Air Authority notes that weatherstripping also goes at the tops and bottoms of window sashes to help prevent air leaks due to windows.

Door sweeps go along the bottom of exterior doors to prevent air from entering your home from the gap between the door and bottom jamb. Be careful with the thickness and material of a door sweep because a sweep can damage your flooring or carpet over time. Door sweeps come in rubber, drip-cap, and brush types. Door snakes are long, skinny tubes filled with weighted items. Door snakes are temporary, and they fill the gap underneath exterior doors easily and efficiently.
Caulking represents a quality, semi-permanent solution for air sealing. Apply caulk where the window or door frame meets the building on the outside. On the inside, use temporary caulking to keep your windows shut for the winter if you don’t plan on opening them until spring. Simply peel the caulking away from the window and open it. Air Authority recommends high-grade silicone caulking for best results. Follow the instructions carefully because caulking won’t cure properly if the temperature gets too cold shortly after installation.
Foam fill insulation expands after you spray it into an open space. Consider minimally expanding foam fill for gaps around pipes, vents, and cables that penetrate your walls. Larger holes may need multiple applications of spray foam. Use this insulation outdoors because spray foam can have an odor after a while. Air Authority wants your home’s interior to be as comfortable and odor-free as possible!
