Fiberglass – Good

Fiberglass insulation is the most common form of home insulation and is made from a silicate fiber primarily composed of glass. As an insulator, it slows the spread of heat, cold and sound in structures. In homes, fiberglass insulation can be installed in various parts of the building envelope. It can be pink, yellow, white or green, depending on its manufacturer, and has a spongy feel. Commonly found in blanket form, called batts, it is available in bags containing standard pre-cut lengths and widths. Batts are typically stapled into place. It also comes in bags as loose fill that can be blown into attic, wall and floor cavities

The Positives:

  • Less expensive than the other insulation products
  • It poses no fire hazard.
  • May reduce residential energy costs up to 40%
  • Very good for sound and noise reduction.

The Negatives:

  • Does not seal wall and ceiling spaces very tightly.
  • Fiberglass settles and begins to sag over time.
  • As it loses its overall effectiveness over time it begins to create more dust and particulate matter throughout your home.
  • If particulates from fiberglass are inhaled, it could cause lung damage or lung disease.
