    Default Spray Insulation

    Can you use spray insulation in the walls of an existing home? Are there companies who will inject the exterior walls of your existing home, or do you have to remove drywall?

    Thanks,
    Glenn

    Default Re: Spray Insulation

    There are companies out there that inject foam insulation. They have to make two holes in each stud bay, basically every 16" but fixing small holes is a lot cheaper than replacing drywall!
