What are the benefits of fiberglass batts insulation?

One of the benefits of fiberglass batts insulation is that it's a natural fire retardant. Fiberglass batts insulation is considered Class A material, which means it has an exceptional ability to resist catching fire or continuing to burn after being ignited.

In a sealed container, a laboratory test showed conclusively that cotton batting under less pressure for about two hours could withstand open flame without igniting and then went out again when the flame was withdrawn. Another benefit of fiberglass batt insulation is that it doesn't require drafts from nearby furnaces or wood stoves to work properly because the dense insulating material resists airflow by molecular attraction instead of convection. In addition, fiberglass batt insulation does not absorb moisture from its surroundings like some other types of insulation.

As a Class A material used in building construction, fiberglass insulation can contribute to obtaining a Fire Code rating for a building because it's just not possible for flames to spread through fiberglass batts insulation very easily. Isocyanate is the primary component used to make most rigid foam boards, and some manufacturers incorporate this chemical into fiberglass batts insulation. The use of urea formaldehyde, a Class A material used to make some rigid foam boards, is limited in the United States because it emits excessive amounts of formaldehyde gas when exposed to heat, making any room with this type of insulation more dangerous for anyone with sensitivities to chemicals.

In addition to these outstanding safety features, fiberglass batt insulation has another added benefit: its low cost makes it one of the most affordable types of insulation available.

How does fiberglass batts insulation work?

You would need to install it inside an unheated space to feel the benefits.

The question is essentially asking, "Does insulation work to keep a room warm?" and the answer is no. That's not what insulation does. Insulation also assists in keeping heat from escaping through walls, ceilings and floors during winter months, however it has limited benefit if installed in unheated spaces such as attics or basements.

Fiberglass insulation is made of extremely small glass fibers held together by a binder. These tiny, lightweight particles are mixed with water or another type of solvent to form slurry, which is then poured into forms where the fiberglass mat takes shape. The mats are placed in compression so they can be handled more easily during construction.

Insulation helps keeps rooms warmer by reducing air movements that generate drafts within the home as well as reduce energy loss through walls via thermal conduction or convection currents outside of your property into your house. In essence, insulation works best when there are no holes for air currents to pass from one side of the insulation to the other or if there are no large temperature differences on either side of the insulation.
