The original blown-in wall system, commonly known as BIBS insulation, was patented and trademarked more than 30 years ago.
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.
