EcoSmart – Home Air Sealing Services
Sealing your home from air leaks
is a smart choice. Homes consume an alarming 21% of the energy used in the United States. Most of that energy is spent heating and cooling your house. And even worse, a significant portion of that energy may be spent heating and cooling your backyard and front porch, through leaks and holes in your building envelope. Air sealing can reduce those issues.
Although some of the air leaks in your home are visible to the untrained eye — around old and untreated doors and windows, for example — much of the average home’s air leakage takes place in areas you don’t see. One of these areas is referred to as stack effect or chimney effect. In this scenario, cold air infiltrates your cellar through leaks and cracks in the foundation and walls, and begins rising. It works its way up through the floors and/or walls, then up into your attic through structural defects, holes in your ceiling, recessed lighting, leaky duct work, the furnace flue, the plumbing stack, or a poorly sealed attic floor. A home performance contractor doing air sealing work in your home will generally focus on the basement and attic sealing to minimize the stack effect, and thus the unwanted air movement throughout your home.
Perhaps equally important, air sealing is crucial for maximizing the performance of insulation
, the other major component of your home’s building envelope. Insulation provides a range of thermal resistance, know as R-Value. The R-Value of insulation is determined under the assumption that there will be no air infiltration throughout the insulation, i.e. it assumes that there will be adequate air sealing around the insulation. Once insulation is left exposed to air movement (air moving up through your attic floor, for example), R-Value decreases.
The Benefits of Sealing Your Home
Home air sealing not only help retain your home inner temperatures, but it helps improve the efficiency of your insulation. Window seals, door seals, duct seals, and attic sealing can all dramatically improve your energy savings and your comfort level.
Air sealing in an average North American home can lead to up to $600.00 in annual energy savings. Furthermore, Connecticut’s unique Home Energy Solutions program, sponsored by the Connecticut Energy Efficiency Fund
, can dramatically reduce the upfront cost — meaning that your home can be more comfortable, healthier, greener, and more energy efficient, for a very affordable rate. Contact us
