Batt Insulation for Your Home

Protect your home from outside air with batt insulation. Use this versatile material to insulate the garage and the attic, as well as your home’s walls, floors and ceilings. Shop for the right insulation for your next project at Lowe’s, where you can find exactly the type you need, as well as the most respected brands, including ROCKWOOL insulation and Owens Corning insulation.


Fiberglass batt insulation effectively insulates your home while simplifying installation, making it ideal for do-it-yourself projects. Advanced fiber technology creates a tightly woven network of fine fibers that make up a durable, high-performance layer of insulation. This insulation also cuts, splits and glides into place easily. Plus, it’s shed-resistant, which makes for easy cleanup.


Wool insulation is a natural alternative to fiberglass insulation that’s made from the coats of sheep. Some types of wool insulation are highly absorbent, which can help prevent the accumulation of mold and mildew in your walls.


As the name implies, soundproof insulation will help cut down on excess noise and echo in a room, especially if it has high ceilings or hardwood floors. If you live in an urban area, adding soundproof insulation will also shield your living space from noisy pedestrians and traffic.


Evaluate the different types of insulation available based on their R-value, which indicates the measure of thermal resistance. The higher the R-value, the more effectively the insulation can work to prevent heat transfer. Find R-19 batt insulation and R-21 insulation, which are ideal for insulating homes framed by 2-inch-by-6-inch lumber. To determine the right amount of insulation for your project, check out our R-Value Insulation Calculator.
