Insulating your attic is a relatively low-cost way to improve the energy efficiency, comfort and durability of your home. It prevents warm air from escaping in winter and cool air from leaking in summer, helping your HVAC system work less to lower energy bills. It also reduces noise and provides a barrier against pests.

When installing insulation, you can use one of three methods:

This method involves laying rolls of fiberglass batts or cotton or polyester wool over the attic joists. The joists should be insulated to the height of the ceiling drywall, with at least two layers of blanket or loose fill. The installer should also install polyethylene over the joists and seal all holes in the attic floor, attic hatches and structural components.

The next step is to insulate the attic floor and ductwork with a thick layer of blanket or cellulose loose-fill. This can be done with a variety of products that are typically sourced from recycled glass, newspaper and cardboard, or industrial waste. The product is blown into place by a machine that uses a pneumatic tube. If you choose cellulose, the installer should plan to add 20% more material than required to account for settling.

Rigid foam insulation is another attic insulating option. This product comes in panels of polystyrene, polyisocyanurate or polyurethane and is installed against the attic’s structural components. This type of insulation has an R-value greater than that of traditional fiberglass batts and is more durable.
