Your home’s insulation is one of the key factors that create a comfortable environment, slowing the loss or gain of heat.
Since 1938, fiber glass insulation has been one of the most popular options for commercial and residential projects alike. Fiber glass insulation is trusted for its ability to reduce utility costs, increase comfort, and make buildings more energy efficient.
Understanding the Benefits of Fiber Glass Insulation
Typically manufactured in two different forms — pre-cut batts and blown-in loose-fill — fiber glass building insulation is used primarily for thermal and acoustical purposes in wall cavities, attics and other critical open spaces in building assemblies. One of its key advantages is value. Fiber glass insulation has a lower installed price than many other types of insulating materials and, for equivalent R-Value performance (i.e., thermal resistance), it is generally the most cost-effective option when compared to cellulose or sprayed foam insulation systems.
Durability
Fiber glass insulation is moisture and fire resistant throughout its life. This ensures safety and improves the value of your building. When exposed to moisture, fiber glass insulation neither absorbs nor holds water. Made from sand and recycled glass, fiber glass insulation is naturally noncombustible and remains so for the product’s life. It requires no additional fire-retardant chemical treatments. Many building codes also recognize fiber glass insulation as an acceptable fire stop in wood- and steel-framed wall assemblies.
Acoustic control
Naturally sound absorbent, fiber glass insulation reduces sound transmission in any setting. When acoustic control is a primary goal, fiber glass insulation can increase the sound transmission class (STC) anywhere between three and six points.
Sustainability
Between 1992 and 2000, the fiber glass insulation manufacturing industry recycled more than 8 billion pounds of pre- and post-consumer glass containers, eliminating the need for millions of cubic feet of landfill space. Fiber glass insulation has significant recycled content, with some batt and loose-fill insulation products containing up to 80 percent recycled glass. The other main ingredient in fiber glass insulation, silica sand, is an abundant, naturally renewing resource, limiting environmental impact in the manufacturing process.
