Fiberglass Insulation

Here at A Plus Insulation, LLC we offer Fiberglass Insulation. Typically manufactured in two different forms — pre-cut batts and rolls, and blown-in loose-fill — fiberglass.

Fiberglass is a traditional form of insulation. It is made from very fine fiberglass slowing down the spread of heat, cold and sound. This is typically found in older homes.

Advantages

  • Fiberglass insulation is inexpensive.

  • Fiberglass
    does not shrink.
    
  • Fiberglass
    insulation does not burn.
    
  • Fiberglass
    insulation is available in medium- and high-density options (roughly
    R-11 and R-15 for a standard 2-by-4 wall and R-19 and R-21 for
    2-by-6 wall)
    
  • Blown
    fiberglass surrounds everything inside wall cavities, providing a
    more consistent layer of insulation.
    

Disadvantages

  • Protective gear must be worn when installing/removing: the tiny slivers will lodge in skin and are small enough to be inhaled.

  • Unless
    you use plastic-sealed batts, fiberglass insulation requires a vapor
    barrier to protect it from moisture.
    
  • Fiberglass
    blankets do not seal wall and ceiling spaces very tightly.
    
  • Fiberglass settles and sags, so its R-value decreases over time.

  • Standard fiberglass can be crammed into smaller spaces to improve its R-value, but it needs venting if this is done (to avoid moisture buildup which will destroy its efficiency).

  • Once wet or damp, insulation may become moldy, which can spread to wood or other areas.

  • Fiberglass can be a warm and cozy environment for rodents to set up a nest.

  • Over the years, it can sag, fall out, or collapse, leaving air gaps where air can penetrate the house.

  • It is difficult to set batts into small spaces and unusual/awkward gaps.

  • Some fiberglass insulation still uses formaldehyde as a binder, which leaks out into the air. Inhaled slivers of fiberglass irritate the alveoli and can cause lung disease.
