Attic in Deal, NJ Requires Air Sealing Before Installing New Insulation

Wednesday, July 10th, 2024 by Michael Gloeckler

Challenge

After inspecting this home in Deal, NJ, we found the attic was not properly air sealed. Before installing any insulation, we need to air seal the attic. Homeowners lose most of their conditioned air through the attic. Top plates in the attic can have ¼ to ½ inch gaps, causing air leakage similar to having a window open 4-6 inches year-round, making it impossible to maintain a comfortable temperature.

Solution

We highly recommend air sealing the attic and would never install insulation before doing so. These images show the gaps in the top plate and drill holes, highlighted in green. By using ZypFoam sealant on these seams, we can meticulously air seal the attic, effectively "closing the window" and ensuring an airtight space before installing R-60 cellulose insulation.

After pulling back the exposed fiberglass insulation, we discovered gaps where conditioned air is leaking into the attic. This leakage increases the homeowner's energy bills and reduces their comfort.

We marked the gaps in the top plate with green highlights.

After pulling back the exposed fiberglass insulation, we found gaps and drill holes for wires and pipes through which conditioned air is leaking into the attic. This leakage contributes to higher energy bills for the homeowner and decreases their comfort.

We marked the gaps in the top plate, drill holes, and piping with green highlights.
