Attic Heat Retention Prevention

The attic is one of the most attic insulation areas to conserve energy in your home. It reduces air flow between the living spaces below, allowing your HVAC system to maintain comfortable temperatures and decreasing your monthly energy costs. But if your attic is poorly insulated, your home’s air conditioning will be working much harder than necessary during the summer months.

Without adequate insulation, the sun’s radiant heat is absorbed by your roof’s surface and then transferred into the attic space below. This transfer occurs through three mechanisms: conduction, convection, and radiation. Insulation reduces all three, minimizing the heat transfer and preventing it from entering living spaces below.

Key Attic Insulation Considerations

Attic ventilation is also key. An inadequately ventilated attic will trap heat, leading to hot shingles and making it difficult for your cooling systems to maintain a comfortable temperature. Proper attic ventilation can also help prevent the formation of ice dams in winter.

Before adding any attic insulation, it’s essential that a professional performs a thorough attic air seal. Tiny leaks in the attic floor and penetration points allow heated air to escape into your living spaces, reducing the effectiveness of your cooling system. A professional can use spray foam or foam board to air seal these areas, with the latter being easier for a retrofit installation. Once these areas are sealed, blown-in insulation can be added. When properly applied, this material conforms to irregular spaces and fills gaps uniformly.
