Adding Insulation to Existing Attic

One of the best ways to save energy and reduce your heating and cooling costs is by putting more insulation in the attic. It can also help slow the buildup of heat that causes ice dams on roofs and prevents air from moving freely through homes.

This article describes how to determine whether you need more insulation, how much to install, what tools and materials are required to do the project yourself if you choose to DIY, important safety considerations and step-by-step instructions for getting the job done. It also provides advice on when to hire a professional.

Top Benefits of Combining Attic Insulation and Pest Control

The attic is often overlooked as an area where you can make significant energy savings in your home. The primary reason for this is that most homes are built with inadequate attic insulation, which allows hot air to escape into the living space below. Insulating your attic increases the R-value of your home and can greatly reduce your energy bill, especially in cold climates.

There are several types of attic insulation available to you, including fiberglass batts, cellulose and structural insulated panels (SIPs). Fiberglass is the most common and the least expensive option. It is made of recycled materials and offers an R-value between R-3.6 and R-3.8 per inch of thickness. Blown-in cellulose is a more eco-friendly choice, made from recycled newspaper and cardboard, and can be used with any attic ventilation system. It can be installed over existing insulation, but it is recommended that you add a vapor retarder underneath to prevent moisture from seeping into the attic and damaging your house.
