Basic Construction of Fiberglass Insulation

Fiberglass consists of glass fibers arranged to form a strong material. As the fibers bunch together, air pockets form that limit heat conduction. It is commonly shaped into blocks called batts for insertion into wall stud cavities. Alternatively, workers may use a blown-in fiberglass technique to fill spaces in existing structures. In either installation method, workers need to wear masks to prevent breathing in the fibers. Workers also need to wear long-sleeved shirts and gloves, and don eye protection.

Advantages of Fiberglass

In a typical building, fiberglass should last about 50 years. Insects do not eat fiberglass. The material resists moisture and fire. It readily absorbs sound, helping to dampen noise between rooms of a house. Fiberglass usually costs less than other types of insulation. For environmentally conscious customers, the fiberglass may be sourced from recycled materials, and recycled at the end of its life.

Important Specifications for Insulation

The degree of insulation provided by fiberglass, or any other material, is known as its “R-value.”  Generally, the greater the thickness, the greater the R-value. Higher density material has greater insulating properties. Recommended levels of insulation for a home, depends on the climate. Pittsburgh rests in zone five, according to the International Energy Conservation Code maps. This zone translates to R-values of 38 to 60 for attic spaces. Wall cavities require R-13 to R-21, depending on the heating system.

Fiberglass offers a durable and cost-effective alternative for insulation. As long as homeowners choose installations that offer a sufficient degree of insulation for their needs, they should enjoy lower energy costs and a more comfortable abode for many years.
