Blown in Blanket Insulation System (BIBS)

A blown-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 BIBS insulation are made with 20-30% recycled glass, making it an eco-friendly insulation option.

Benefits of BIBS Insulation System

BIBS insulation delivers the highest R-value available on the market today. Benefits of BIBS insulation include effective sound insulation as well as natural resistance to mold, mildew, pests, and fire. Its capacity for creating a sealed, energy-efficient insulation system makes BIBS a favorite among builders and homeowners alike.

High-Density Loose Fill Insulation

When applied as a blown-in blanket insulation system, fiberglass wool offers the highest R-values in the industry. Depending on the thickness of your walls, the R-value for a BIBS insulation system can range anywhere from R-15 (3.5” thickness) to R-56 (13” thickness). This insulation method also seals thermal gaps in odd-shaped spaces and around penetrations like pipes, wires, and sockets. BIBS is a strong choice to create an energy-efficient insulation system.

The density of BIBS fiberglass loose fill insulation offers reduced air permeability, which helps prevent infiltration from outdoor allergens and dust. Fiberglass wool is also resistant to pests, mildew growth, and mold. With BIBS insulation, your home is protected against potentially harmful airborne spores as well as frame-damaging infestations. BIBS holds its shape over time and won’t shift after installation so your insulation will provide even protection for years to come.

Fire Resistance

Fiberglass wool is naturally non-flammable and non-combustible. BIBS meets ASTM C764 testing criteria for smoldering combustion and ASTM E136 for non-combustion. It is also formaldehyde-free and free of noxious odors. BIBS’ added fire-resistant quality can be useful in fulfilling specific building codes during new construction projects.

Fiberglass BIBS Insulation System Cost Comparison

When compared to standard fiberglass batt, blown-in blanket insulation offers higher R-values and full-seal 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 insulation 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 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 or crawlspace 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 Insulation Installation

Blown-in blanket insulation systems are a popular choice for sidewalls, attics, and crawl spaces. 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 insulation 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 crawl space to be filled. Technicians make an installation hole in the barrier fabric to fill the open wall cavity. Using a pneumatic blowing system, technicians then fill the open space to seal all edges, electrical wires, and openings. This process reduces the need for measuring, cutting, and seaming rigid insulation or batt pieces. The fabric insulation barrier also reduces installation mess and simplifies contractor cleanup.
