Microlite® fiberglass insulation is a lightweight and highly resilient blanket-type thermal and acoustical insulation made of flame-attenuated glass fibers bonded with thermosetting resin. The fibers that make up Microlite® are noncombustible and do not support fungi. Microlite® fiberglass blankets are also unaffected by oil, grease and most acids.


Microlite® fiberglass insulation is used in a variety of appliance, equipment and office furniture applications which require high thermal and acoustical efficiency in a minimum space, such as acoustical panels/partitions, pipe wrap kits, HVAC equipment and other appliances.


Microlite® is a lightweight fiberglass blanket that uses minimal space to give excellent thermal and acoustical insulation. The countless air spaces in Microlite® create effective sound absorption as well as thermal properties. Perceived noise from air movement and mechanical equipment is noticeably reduced.

Because of its resiliency and flexibility, this fiberglass blanket resists settling, breakdown, sagging from vibration and damage from impact. Microlite® fiberglass insulation forms easily around corners and curves. It is easily cut to size or shape with a knife or in die cut presses.
