Air Sealing a Leaky Attic Floor in Sea Girt, NJ
Upon inspecting the attic of this homeowner in Sea Girt, NJ, we discovered that the floor was not properly air sealed. Without air sealing, warm air from the homes conditioned space escapes into the attic during winter, needlessly heating the attic and increasing energy bills. This also leads to discomfort in colder months. In summer, the attic can reach temperatures over 140 degrees Fahrenheit, and without proper air sealing, this heat infiltrates the indoor space as hot air seeps through gaps in the attic floor. Upon examining these images, we can observe gaps in the floor that are approximately 1/2 inch wide, including gaps around the pipe and several open drill holes. To solve these issues, we use ZypFoam sealant to seal top plates, sill plates, and any exposed holes or gaps in the attic floor before insulation. This process creates a more effective thermal barrier between the attic and conditioned living space. By air sealing the attic, we significantly enhance comfort and energy efficiency in this home.
