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.
