Air sealing the attic floor is one of the most important energy-saving and comfort-enhancing upgrades you can make if you are using blown or batted insulation in your attic. The most important and overlooked air leaks are often hidden throughout your attic space. Air leaks between your home and your attic can bring in dust and unwanted temperatures year-round. Blown and batted insulation materials have a high air permeability and are not considered air barriers. Air leaking through insulation is similar to air moving through an air filter, which reduces the insulation’s thermal resistance. The correct way to complete an attic is to combine air sealing the attic floor with insulation, which creates a thermal barrier.

Perkins Inc. specializes in multiple solutions for sealing air leaks at the attic floor to increase efficiency, air quality, and comfort in your home. We offer various solutions and products to achieve air sealing the attic floor, but we only perform this service if the old insulation has been removed from the home. Removing the old insulation from the attic is the most important task to ensure the effectiveness of the air seal. The air leaks between the house and the attic are often widespread, and it can be challenging to locate them under the insulation. Digging and searching for these leaks by hand typically destroys the coverage of the insulation, and there is no guarantee that all the areas of interest will be found. It is an inefficient and difficult process to try to air seal with existing insulation, and the results will not be satisfactory.
