Faced Fiberglass Metal Building Insulation

Faced / Laminated MBI

Bay Insulation's faced MBI fiberglass is a resilient, flexible fiberglass blanket laminated to a high quality vapor retarder facing. It is the most common and cost effective solution used for insulating pre-engineered metal buildings.

Faced fiberglass can be installed as a single layer, or combined with unfaced MBI fiberglass and various support hardware to create a "High R-Value System".

FAQ's and precautions regarding metal building insulation»


NAIMA

NAIMA 202-96® fiberglass metal building insulations are blanket insulations engineered specifically for metal building construction. These insulations are certified by the NAHB to meet the 202-96® standard for flexible fiberglass used in Metal Buildings and are engineered and produced to maintain their stated R-value after the rigors of facing lamination, shipping, storage, and handling that occurs during installation. Bay Insulation uses NAIMA 202-96® fiberglass when laminating R-10, R-11, R-13, R-16, R-25 and R-30.

NIA

The NIA (National Insulation Association) standard provides a basis for quality control procedures of the lamination process and for certifying post-laminated R-Value.  Every Bay plant is compliant with the standard for "Certified Faced Insulation".
