Photo Album: Attic Air Sealed in Hanover, MD

The beginning of last summer, this client had us come out to her house and make a few suggestions about what could be done to make her home more comfortable, but she wasn't ready to go through with the work. After suffering through a long hot summer, and then a cold winter, she became eager to get the work done before the weather got unbearably hot again. By making upgrades to her two attics, we were able to give this client a nice and comfortable home all year long.

Attic Before Being Air Sealed

The attic in this picture is not ideal. There is insulation, but some of it is deteriorated (the parts that have black and gray spots) and there is no air sealing. This is a bad combination that does nothing to protect your house from extreme weather and dirty air.

Air Sealing Attic Penetrations

Even small cavities in your attic can create a lot of air leakage. We seal these up by applying a combination caulk (this technique is pictured here), foam board, and spray foam.

Install SunChuter Radiant Barrier

Installing a radiant barrier (that's the aluminum looking boards you see here) is a great way to reduce heat in the attic, which consequently affects the heat throughout the rest of the house. They work to reflect radiant heat rather than absorbing it.

Spray Foam Air Sealing

Here we have pictured a great air sealing product. Closed cell spray foam is expansive in nature and works to cover the desired area completely while forming an airtight seal.

Blown In Cellulose Insulation

After air sealing, choosing the right kind of insulation is also really important in making your home efficient and comfortable. We installed cellulose insulation here because of its high R-Value and density.
