What is Fiberglass Insulation?

Fiberglass insulation has been around since 1932. It primarily is made out of glass fibers, stone, or iron ore slag. Older fiberglass can possibly contain formaldehyde however, most manufacturers have produced formaldehyde free fiberglass since the early 2000's. Fiberglass insulation comes in many different colors and forms from loose fill (blown-in) and batt insulation both faced or un-faced. It is important to note that faced batt fiberglass has a paper backing to one side. This acts as the vapor barrier which, in our climate, should always be facing the heated side (toward the inside of the home).

Common Areas Fiberglass is Used:

  • Exterior Walls
  • Knee Walls
  • Attic
  • Rim Joist

Noise Reduction:

Some fiberglass products can be added during a new build or remodel in certain wall cavities to sound deaden walls or rooms. The fiberglass material is generally made out of iron ore slag or sand. This also makes the product not only act as a noise reducer but a fire-blocker as well. Most mineral fiber products have a melting point of around 2150°F.
