It has long been recognized that adding fiber glass insulation to exterior and interior walls as well as floor and ceiling assemblies is a cost-effective way to improve noise control. But the product is not enough; how the product is installed is critical in accomplishing noise reduction.
The Blow-in-Blanket System, or BIBS, offers you both an effective acoustical material and an assurance of properly installed product. Here's why: BIBS uses only high quality fiber glass insulation, produced by CertainTeed or Johns Manville. Unlike other insulation systems that may leave voids or gaps, BIBS completely fills the space reducing sound transmission through the wall cavity. Testing has shown that fiber glass can add four to ten points to the STC (sound transmission class) of a wall or ceiling assembly. And fiber glass is permanent; it doesn't settle or deteriorate over time, so it doesn't lose it's acoustical effectiveness. |
