At Quantum Performance Buildings products, we offer a full line of insulation materials. Fiberglass Bib System is a good alternative to the traditional fiberglass batts. It offers better coverage and more restriction to air flow. It’s not as cheap as fiberglass batts but it will provide extra energy savings which will pay for itself in the long run. Fiberglass bib insulation does not perform as well as spray foam, but it does a good job.
