Where Does Air Infiltrations Come From?
Someone has to take the blame. In cases of leaks and air infiltration, each of the following is guilty as charged:
Doors: frame, sides, bottom, threshold
Windows and patio-doors
Air conditioner and air vents
Electric outlets and switches
Hatches and ceiling lights
Joints between baseboard and floor
Unsealed wall openings for technical installations
And every little leak we easily forget.
You must inspect these strategic points in order to make your house as air tight as possible. The more you seal, the more you save, the more you enjoy. Sealing and weatherstripping can help you take care of these problems at a very low cost.
