Fiberglass Insulation Companies Lakeland Florida
Fiberglass insulation is made of silica sand and recycled glass, both abundant resources. Producing fiberglass insulation requires melting the materials in a fossil fuel–burning furnace, which consumes substantial amounts of energy and generates greater amounts of air pollution than the manufacture of other insulation types.
If installed properly, there is little danger of inhaling fibers, which are throat, eye, and skin irritants. Although the Occupational Safety and Health Administration still requires cancer warning labels on fiberglass insulation products
Fibers can escape into the air during installation—or if ductwork is not sealed properly—becoming a problem for residents. Because of the concern that fiberglass emits phenol-formaldehyde, some manufacturers have switched to nontoxic acrylic binders.
Loose-fill fiberglass seals air spaces best since it is blown in, preventing air movement and heat loss. Low-density batts are most commonly used, but can lose up to 50 percent of their R-value in cold climates due to moisture infiltration.
