Insul-Quilt has gained a reputation among builders and architects for providing maximum environmental noise reduction. As a result many builders and architects began to use our Insul-Quilts in other projects. These include casinos, airport buildings, mixed-use buildings, retirement facilities, hospitals, schools, office buildings and apartment buildings, as well as hotels and vacation resorts. It is increasingly being used in structures at or near airports, freeways, and other high environmental noise areas.

Insul-Quilt is a state of the art material, which may not only be installed in plenums, but also can be installed directly on walls and ceilings. Weighing only .4 lbs. per square foot it is significantly lighter than most other professional grade materials, yet it absorbs in many cases as much as twice the noise as other materials.

Insul-Quilt is made of a blanket of glass-wool, faced with white fiberglass cloth and backed with aluminum foil. It is approximately two inches thick and four feet wide and is manufactured in varying lengths. Insul-Quilts can be manufactured to each individual client’s needs and even though the standard color-schemes are black and white fiberglass cloths, at our client’s request this cloth can be provided in numerous colors.
