Insulating exterior walls properly with fiberglass batting insulation is essential for protecting your home from the elements. Faced batts and rolls are lightweight, naturally thermal, and acoustical fiberglass made of long, resilient glass fibers.

The facing serves as an integral vapor retarder, reducing the potential for mold and mildew growth and making faced insulation an appropriate choice for external walls. Batts and rolls come in a variety of R-values from R-11 to R-38.

Applications for Fiberglass Batting Insulation

Fiberglass batting insulation can be primarily used to insulate:

  • Walls;
  • Floors;
  • Attics;
  • Ceilings.

The batt itself is very flexible material and usually fits with ease in between wall framing. This makes fiberglass batting insulation ideal for insulating large amounts of framing that may or may not be consistent throughout the structure.

Benefits of Fiberglass Batting Insulation

One primary benefit of fiberglass batting insulation that makes it specifically attractive for homeowners is its fire-retardant properties. The material itself poses little fire hazards and conserves more energy than other types of insulation, helping homeowners save up to 40% on energy costs.

More benefits of fiberglass batting insulation include its:

  • Ease of installation;
  • Budget-friendliness;
  • Resistance to mold and mildew;
  • Eco-friendliness.

Ultimately, fiberglass batting insulation contributes to a more comfortable home year-round.

Expected Lifespan of Fiberglass Insulation

Fiberglass insulation usually needs to be replaced every 15 to 20 years. Any type of water damage due to leaks can reduce the lifespan of the insulation.

This characteristic of fiberglass insulation, however, is offset by the insulation’s ability to conserve energy, keep your home comfortable year-round, and reduce energy bills by as much as 40%.

Fiberglass insulation tends to be a more budget-friendly option for most homeowners than other types of insulation.

Consulting the help of a professional insulation contractor is the best way to tell if your fiberglass insulation needs to be replaced or if it’s the right kind of insulation for your needs.
