Should You Insulate Attic Rafters?

If you want to save money on heating and cooling while making your home more comfortable, insulating attic roof rafters is one of the best investments you can make. Insulation keeps the heat inside during winter and out during summer, significantly reducing your energy consumption and improving your comfort.

Top Benefits of Combining Attic Insulation and Pest Control

Insulating your attic can be a DIY project, and there are multiple products available. Fiberglass batts are easy to unroll and fit between attic rafters, and they can be purchased with or without facing or a vapor retarder. If you choose to use fiberglass, it’s important to keep it away from recessed light fixtures and soffit vents so the air can escape properly.

Another option is foam board insulation, which is a rigid solution that resists moisture and has a high R-Value per inch of thickness. Spray foam is another good choice for tight spaces between rafters, because it expands to fill gaps and create an airtight seal.

The most effective attic insulation strategy is a “warm roof” approach, which involves insulating the rafters, sealing the space between joists and installing a new attic floor, which can help maintain a comfortable climate in the living spaces below. However, it’s important to have proper ventilation in the attic, typically through soffit and baffle vents, as well as a ridge vent up top.
