Insulation in the attic is an important part of a home upgrade that can reduce air leaks, improve comfort and save energy. The right insulation type, R-value and professional installation can make the difference between a comfortable, efficient home and one that’s drafty and wasteful.

Upgrading Attic Insulation is a cost-effective way to boost the thermal performance of your home. It’s also a great way to help reduce your carbon footprint.

The R-value (thermal resistance) of attic insulation is determined by how well it blocks the transfer of heat between spaces. Different climate zones require specific levels of R-value. Local and state building codes typically stipulate minimum R-value requirements.

How Proper Attic Insulation Boosts Indoor Comfort Year-Round

ENERGY STAR provides tips on how to properly measure your attic for insulation and how to choose the best type of insulation. ENERGY STAR also has information on incentives and rebates for attic insulation.

There are a variety of materials that can be used for attic insulation, with different pros and cons. For example, blown-in insulation, which is a loose-fill material such as fiberglass or cellulose, can settle over time and lose R-value. On the other hand, spray foam can seal gaps and cracks and offer a great air barrier.

Rigid foam insulation, which is made from panels or boards of polystyrene, polyisocyanurate, or polyurethane, provides a high R-value per inch and resists moisture absorption, making it durable and long-lasting. It can be installed over existing attic insulation or can be nailed to the structural components of the attic. It requires a skilled installer, however. It is also more expensive than other types of attic insulation.
