Air Sealing & Weatherstripping
Reducing the amount of air that leaks in and out of your home is a cost-effective way to cut heating and cooling costs, improve durability, increase comfort, and creating a healthier indoor environment. Caulking, spray foam and weatherstripping are a few simple and effective air-sealing techniques that offer quick energy savings. Caulk is generally used for cracks and openings between stationary house components such as around door and window frames, spray foam is used in the attic to close air bypass areas and weatherstripping is used to seal components that move, such as doors and operable windows.
Air leakage occurs when outside air enters and conditioned air leaves your house uncontrollably through cracks and openings. It is unwise to rely on air leakage for ventilation. During cold or windy weather, too much air may enter the house. When it's warmer and less windy, not enough air may enter, which can result in poor indoor air quality. Air leakage also contributes to moisture problems that can affect occupants’ health and the structure’s durability. An added benefit is that sealing cracks and openings reduces drafts and cold spots, improving comfort.
The recommended strategy is to reduce air leakage as much as possible and to provide controlled ventilation as needed. Before air sealing, you should first:
- Detect air leaks
- Assess your ventilation needs for indoor air quality.
With a Home Energy Audit by Wortman Central Air, we can identify where your home has air leaks and offer solutions. A blower door will help you see how much leakage is in your home and with the aid of an Infrared Camera these areas can be documented. If you're planning an extensive remodel of your home that will include some construction, review some of the techniques used for air sealing in new home construction and consider a home energy audit to identify all the ways your home wastes energy and money.
Insulation in your home provides resistance to heat flow. The more heat flow resistance your insulation provides, the lower your heating and cooling costs. Properly insulating your home not only reduces heating and cooling costs, but also improves comfort.
Heat flows from warmer to cooler until temperatures equalize. In your home, this means that in winter, heat flows directly from all heated living spaces to adjacent unheated attics, garages, basements, and even to the outdoors (see air sealing). Heat flow can also move indirectly through interior ceilings, walls, and floors -- wherever there is a difference in temperature. During the cooling season, heat flows from the outdoors to the interior of a house.
To maintain comfort, the heat lost in the winter must be replaced by your heating system and the heat gained in the summer must be removed by your cooling system. Properly insulating your home will decrease this heat flow by providing an effective resistance to the flow of heat.
We can blow in insulation (Fiberglass or Cellulose) in many spaces. From your attic, cathedral ceilings, floors to wall insulation. For a proper assessment call us for an Home Energy Audit.
