The BIBS system with Climate Pro Fiberglass Insulation

JM Formaldehyde-free™ fiberglass building insulation offers the thermal and acoustical performance you expect from fiberglass—and it improves indoor air quality, because it’s made without formaldehyde. Why is that important? Because reducing overall formaldehyde levels in the home creates a healthier living environment, and choosing JM Formaldehyde-free™ insulation is one way of achieving that goal. JM offers a complete line of Formaldehyde-free™ fiber glass building insulation. Visit or for more information.

The BIBS system is a patented process for installing JM Climate Pro loose-fill insulation behind a proprietary fabric. Climate Pro insulation is blown in behind the BIBS system fabric for complete coverage and high R-value efficiency in any size or shape cavity. The BIBS system provides a custom fit for thermally and acoustically superior insulation in walls, ceilings and floors. When installed to exact specifications, the BIBS system with Climate Pro insulation does not settle, retaining its original R-value.

The BIBS system with Climate Pro blowing wool insulation is ideal for all wall cavities and the irregular and nonconforming areas around custom windows, arches, cathedral ceilings, and floors.

Note: In colder climate areas, vapor retarders are often placed toward the heated or conditioned side of the wall. This is done to reduce water vapor penetration into the wall from the building interior. Check your local building code for vapor retarder requirements.

Store insulation indoors. Keep insulation clean and dry at all times. When transporting, cover completely with a waterproof tarpaulin as necessary.

Only certified contractors can install the BIBS system. Contact your local JM sales representative for an authorized contractor.
