BIBS® Technical Specifications

Technical data for the BIBS® system varies by country. The below data is specified by the insulation manufacturer for approved blowing wool fiber based on installation by a trained and certified contractor when installed correctly.

Standard Densities

The approved use fiberglass blowing wools must be installed to a specified density which correlates to an attainable R-value. R means resistance to heat flow, and the higher the R-value, the greater the insulating power.

Approved BIBS® Fibers

The BIBS® system can only be installed using approved fiberglass blowing wool. These fibers have been laboratory and field tested to help ensure a level of performance of this premium insulation system. The BIBS® system only recognizes specific brands of blowing wool insulation.

CertainTeed

The Optima® system of fiberglass blow-in insulation is a thermal and acoustical insulation for sidewalls, cathedral ceilings, and other closed-cavity applications. The insulation is an unbonded, white, loose-fill virgin fiberglass designed for pneumatic installation behind non-woven Optima®fabric (or equivalent).

InsulSafe® SP and Insulsafe® XC are fiberglass blowing wool insulations used in residential and commercial construction as a thermal and sound absorbing insulation in open (attic) and closed (sidewalls/floor) construction cavities.

Knauf Insulation - BIBS® Technical Specifications

Knauf

Knauf Insulation’s Jet Stream® ULTRA and Jet Stream® MAX fiberglass blowing insulation are unbonded, virgin fibrous glass blowing insulations designed with optimal thermal properties, in addition to excellent coverage and blowing characteristics. Jet Stream® ULTRA and Jet Stream® MAX fiberglass blowing insulation are installed in open attics of both new and existing structures and/or in closed cavity applications with the BIBS® system, in which ventilation is not required.

Johns Manville

The Johns Manville Climate Pro® offers greater consistency of coverage and low dust, resulting in more efficient and comfortable installations. It offers R-values from R-11 to R-70. 

Johns Manville Spider® loose-fill insulation is blown in behind the BIBS® fabric for complete coverage making it easier to install at R-15 and R-23 in 2×4 and 2×6 walls without bulging. The JM Spider® solution does not settle, retaining its original R-value and energy efficiency.
