If you need to insulate your home, start by shopping insulation – from spray foam to fiberglass & more – with quality brands like CertainTeed and Roxul. Lowe's supplies your weatherproofing and soundproofing needs with an array of home insulation products. To stop cold or moisture from seeping in through doors or windows, try house wrap or garage door weather stripping. If your attic or basement needs insulation, you should compare the R-value (grade given for heat resistance) for each product in making your selection. Higher R-value typically means you’ll better insulate your house or garage. Other factors, like local weather conditions, humidity and wind, may also affect the best insulation choice for your needs. Learn more about energy-efficient insulation options or visit Lowe's for assistance. For standard attic or basement insulation, we carry top brands and products including Touch n' Foam spray foam insulation, GreenFiber cellulose blown-in insulation and more.
