DESCRIPTION OF PROPERTIES

Fiberglass insulation is made from silica, sand, limestone, boron, product from resin, and cullet.

Fiberglass used boron to improve flexibility, but this materials is a finite recourse.

Partially recycle, max 35% from recycle materials (post-industrial recycled glass)

expensive productive chain environmental P.O.V.

much more expensive than mineral wool

US insulation that is produced with acrylic binder, rather than phenol-formaldehyde binder.

 PROS

Long life expectancy and durability, low maintenance.

Contain an average of 25% recycled material: 18% post-consumer bottles and 7% post-industrial cullet.

the possibility to be reused or recycled.

 CONS

Fiberglass insulation is an irritant and must be installed carefully, using proper protective gear and precautions.

There are few opportunities to recycle fiberglass at the end of its useful life.

In some document is reported that fiberglass may have the "same potential for inducing cancer as asbestos fibers of the same dimensions". Even if that is not proved it should be handled with caution.

Erosion for sand and limestone mining.

Air pollution during manufacture process due at the energy use.

High embodied energy, more than 15 times cellulose insulation.

Workers and installation process has to be under control.
