Fiberglass insulation is composed with primarily natural ingredients such as sand, and recycled glass. Installing fiberglass in your new or existing home reduces energy costs, improved the comfort of your home, and has a low cost compared to other types of insulation. Fiberglass can be installed blown in insulation, attic insulation, wall insulation and other insulation application.
Thermal performance and energy efficiency
Fiber glass insulation helps make buildings more thermally efficient by better retaining the desired temperature of enclosed spaces, whether they are heated or cooled. Its thermal performance reduces utility costs for building owners, conserves nonrenewable fuel sources and provides greater occupant comfort (when used in conjunction with appropriately sized heating and cooling equipment).
When exposed to moisture, fiber glass insulation neither absorbs nor holds water. If fiber glass insulation does get wet during or after installation, installers should visually inspect it on all six sides for contamination. If the material appears free of visible defects, installers must dry it thoroughly to restore its full R-Value. Once the area surrounding the insulation has also been inspected, cleaned and fully dried, the fiber glass insulation can be reinstalled and will regain its original R-Value.
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.
Fiber glass insulation is a naturally sound-absorbent material that significantly reduces sound transmission in wall, ceiling, floor and HVAC assemblies. The first inch of fiber glass insulation in a building cavity can increase an assembly’s sound transmission class (STC) value by three or four points in some constructions. Each additional inch can further increase the STC rating by two points.
Additionally, fiber glass insulation offers design flexibility. Greater amounts can be installed in some sections of a building to increase overall thermal performance and compensate for areas with lower thermal values, such as windows and doors. It enables a wide range of R-Values.
