Attic Protector® blow-in fiberglass insulation fills those hard-to-reach cavities and corners in attics. With the help of a portable blowing machine – which can be rented from your local home improvement store – installation is easy and efficient. When this insulation is applied to the recommended thickness and specifications, your home will benefit from energy efficiency and minimal heat loss. Plus, our Attic Protector insulation won't settle, decay, or provide food for animals or microbes for the life of your home.
