Home Wall Insulation Products

Home wall insulation helps slow the movement of heat throughout the walls of a residence, which helps keep indoor spaces cooler in the summer and warmer in the winter months. Residential wall insulation can improve comfort and help lower heating and cooling bills. The best type of insulation for walls depends on factors like climate and wall construction. The R-value of insulation, a measure of its resistance to heat flow, is essential. Homes in colder climate zones generally need insulation with a higher R-value for better protection against the cold. Both exterior and interior wall insulation play important roles in the home. Exterior wall insulation supports thermal comfort and energy efficiency, while interior wall insulation enhances acoustic comfort, together creating a more comfortable home environment. 

Interior insulation can help reduce noise between rooms and is often used in walls between bedrooms, bathrooms, or living spaces. Exterior insulation provides an effective barrier against outdoor temperatures and is commonly installed along basement, foundation, and exterior-facing walls. Whether insulating interior walls for noise control or exterior walls for added protection, choosing the right material makes a big difference. 

Owens Corning offers fiberglass, mineral wool, XPS, and spray foam products for various wall applications and conditions. Fiberglass insulation is often used in interior walls, such as between bedrooms, bathrooms, or home offices, to reduce noise and improve comfort. It is available in flexible batts, rolls, and loosefill options, making installation more manageable for both new construction and retrofit projects. Our mineral wool products are ideal for areas where fire protection and sound control are essential, such as furnace rooms, laundry rooms, and garage walls attached to the house. It provides moisture resistance for foundation walls (both interior and exterior) and below the slab, making it a strong choice for basement and garage walls, as well as other areas where damp conditions are common. XPS insulation products can be used above grade as continuous insulation on exterior walls in wood or metal-framed homes to help create a continuous layer of insulation that improves energy efficiency. Certain spray foam insulation can seal gaps and hard-to-reach areas, such as around window frames or electrical outlets, helping to create a tighter, more energy-efficient home.
