Find the Right Home Insulation at Lowe’s

Whether you’re looking for attic insulation, basement insulation or another type of home insulation, we have it at Lowe’s. Insulating your home can increase your home’s energy efficiency, lower energy bills, and provide sound and moisture control. All of these factors can make the cost to insulate a good investment in your home.


There are many different types of insulation, including batt insulation, blown-in fiberglass insulation, reflective insulation, R-13 insulation, window insulation, radiant barrier insulation and roll-in insulation.

It can be used under floors, between studs in the wall and in attics, basements, ceilings and crawlspaces. Roll-in insulation keeps your home comfortable, while also providing soundproofing to help reduce unwanted noise.
