Blow-In Blanket®️ Insulation System (BIBS)

A Blow-In Blanket®️ Insulation System (BIBS) is made up of fiberglass blown-in wool specifically manufactured for use with this installation method. This installation method creates a tight fill around pipes and other irregular features to provide a high R-value and thermal protection in an easy, effective manner. BIBS is used in residential and commercial settings for its high density and big returns on energy costs. Many brands of fiberglass insulation are made with 20-30% recycled glass, making it an eco-friendly insulation option.

Benefits of BIBS Insulation System

  • High-Efficiency R-Values: BIBS delivers the highest R-value available on the
    market today.
  • High-density Insulation: BIBS fills thermal gaps in odd-shaped spaces and around penetrations like pipes, wires, and sockets.
  • Quiet Spaces: BIBS completely fills around objects inside the wall cavity, resulting in excellent sound control.
  • Indoor Comfort: BIBS non-settling qualities reduces air, moisture, pests, outdoor pollutants, and allergens within the framing cavities.
  • Safe Product: BIBS is naturally nonflammable, does not support the growth of mold, and contains no formaldehyde.
  • Environmentally Friendly: BIBS is made from either fiberglass blow-in wool – at least 25% recycled material – or cellulose – a plant-based fiber.

Fiberglass BIBS Insulation System Cost Comparison

When compared to standard fiberglass batt, BIBS offers higher R-values and consistent coverage, which can make BIBS slightly more expensive to install. When considering long-term energy savings, however, a BIBS insulation system can easily provide a positive return on investment. BIBS is usually less expensive than spray foam insulation. As a cost-effective high-density option, BIBS is a good option for large insulation projects.

Fiberglass BIBS Insulation vs. Blown-In Cellulose

Another form of blown-in insulation uses plant-based cellulose fibers, an eco-friendly insulation option. Blown-in cellulose has a slightly higher R-value and better air filtration rate than its fiberglass counterpart. Fiberglass BIBS, however, offers cost savings and may hold up better over time.

Fiberglass is cleaner to install and any dust created during installation is much easier to manage. Fiberglass BIBS also installs faster and blows further than cellulose, which means installers can reach difficult areas of your attic more easily. Fiberglass BIBS holds its shape and won’t shift over time, while cellulose may shift over time, causing gaps or uneven coverage in your insulation. 

BIBS Installation

Blow-In Blanket Systems are a popular choice for sidewalls, floors, and cathedral ceilings. BIBS is installed in new construction or existing homes with exposed wall stud cavities. Homes can be retrofitted to accommodate BIBS insulation, though this may require some light wall renovation, old insulation removal, and interior wall cleaning.

BIBS requires special equipment to blow the fiberglass wool into a pre-installed insulation fabric “netting.” The insulation fabric is fixed around the frame of the wall or cathedral ceiling to be filled. Technicians make an installation hole in the barrier fabric to fill the cavity. Using a pneumatic blowing system, technicians then fill the entire cavity, including behind and around electrical wires, plumbing, and other obstructions. This process reduces the need for measuring, cutting, and seaming rigid insulation or batt pieces. The fabric insulation netting also reduces installation mess and simplifies contractor cleanup.
