This homeowner contacted us because she wanted to save on her heating costs. Air sealing top plates is important in stopping conditioned air from leaking into the unconditioned attic space. Top plates are at the top of every wall in every home. During construction, there is a quarter inch gap left. This gap allows warm air to escape in the winter and cool air to escape in the summer. Our team air sealed all the top plates in this attic. This homeowner will save on her heating costs and her home will be more comfortable year round.
