    More about Owens Corning Residential Floors Products

    Floor insulation has many benefits for homeowners and contractors alike. Home floor insulation helps improve temperature control year-round — keeping homes cooler in the summer and warmer in the winter. In multi-level homes, floor insulation can also reduce noise transfer between levels, creating a quieter and more peaceful living space. By improving energy efficiency, comfort, and durability, floor insulation is valuable in helping to create a more comfortable home.

    For insulation under floors that are exposed, located above unconditioned spaces, or part of multi-level designs, our mineral wool and fiberglass insulation products offer significant benefits. These products are available in a range of R-values to support energy efficiency and indoor comfort. Our fiberglass floor insulation products are available in batts and rolls, some featuring advanced technology for improved handling and flame spread resistance. These insulation batts are also well-suited for noise reduction between floors to improve acoustic comfort.
