The importance of air sealing the building envelope prior to insulating can not be understated. A building that is not properly sealed can lead to air leakage, moisture penetration causing mold and mildew, heating and cooling issues, many more issues depending on the circumstance.
Our team will always recommend air sealing a building envelope prior to providing insulation services. 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 create a healthier indoor environment.
More than any other time of year, you notice your home’s air leaks in the winter. Most people call these air leaks “drafts.” You may feel these drafts around windows and doors and think these leaks are your major source of wasted energy. In most homes, however, the most significant air leaks are hidden in the attic and basement. These are the leaks that significantly raise your energy bill and make your house uncomfortable.
But locating leaks can be difficult because they are often hidden under your insulation. In cold weather, warm air rises in your house, just like it does in a chimney. This air, which you have paid to heat, is just wasted as it rises up into your attic and sucks cold air in all around your home — around windows, doors, and through holes into the basement.
