Thermal barriers, building envelopes, and conduction—these are some of the unfamiliar terms homeowners encounter when upgrading attic insulation in an older home. Even if the specifics of how insulation works or what conduction entails are unclear, upgrading your attic insulation is still a wise investment. Here’s what you need to know about attic insulation, especially if your home is older.
The Proof
The Center for Cultural Sustainability, College of Architecture, suggests that homeowners prioritize four key upgrades when retrofitting an older home for comfort and efficiency. Insulation is one of these essential upgrades. Additionally, they recommend installing a radiant barrier, sealing and insulating ductwork, and ensuring proper attic ventilation.
The attic is not only an excellent area for achieving energy savings but also one that is easily accessible. Unlike some other home improvements that may require modifying or removing historical materials, upgrading attic insulation can be done without disturbing the original character of an older home.
Temperature Matters
The most significant temperature difference occurs between the attic and the outdoors in both warm and cold climates, particularly during the summer. Heat naturally rises and accumulates in the attic, often reaching scorching temperatures of up to 150 degrees. This space also absorbs a high level of solar radiation. Combined with the stack effect, where rising heat is trapped, an inefficient attic can lead to increased energy consumption and reduced home comfort.
By focusing your retrofit efforts on the attic, you can achieve more than just energy savings. Reducing heat buildup in this space and creating an effective barrier to prevent hot air from seeping into living areas will result in a comfortably cool home, making it a pleasant place to spend time. You and your household can enjoy your home as a sanctuary from the heat, maintaining comfort and peace of mind.
