BIBS must be installed by a licensed, certified, and trained professional. Working with a contractor who understands the correct density, proper materials, and has been property trained is critical to the success of this popular system.
BIBS insulation is installed using pure “blowing wool”, another name for specially engineered fiberglass only from manufacturers Johns Manville, CertainTeed, and Knauf Insulation. Fiberglass installed from any other source is not considered BIBS, for example cellulose is not considered BIBS.
BIBS insulation is also installed with a certain type of fabric, available only through Service Partners and their subsidiaries.
How do you know whether you’re getting the real thing or a knockoff system by an untrained worker? Check with BIBCA, the Blow In Blanket Contractors Association by visiting the contractor referral map or call the BIBCA office at 866-330-2427.
