Fiberglass is a type of fiber primarily composed of glass that is used in a wide variety of applications, and is predominantly employed as a residential and commercial thermal insulator.
Fiberglass is an attractive choice for home insulation because it poses no fire hazard.
This thermal insulation (made from fiberglass and its alternatives) conserves 12 times as much energy as is lost in its production, and it may reduce residential energy costs by up to 40%.
Commonly found in blanket form, called batts, it is available in bags containing standard pre-cut lengths and widths.
Batts are available in different thicknesses
With the thicker batts offering a higher resistance to heat flow. This resistance is known as R-value, with common R-values for walls being R11 to R19, and R30 to R38 for ceilings.
An Alternative – Cellulose
Cellulose, a plant-based insulator, is the oldest form of home insulation and, at times, has been produced from sawdust, cotton, straw, hemp, and other plant materials with low thermal-conductivity.
When inhaled, particles can cause coughing, nosebleeds, and other respiratory ailments. Very fine airborne particles are capable of becoming deeply lodged in the lungs and are believed by many to cause cancer and other serious afflictions. OSHA considers this threat to be serious enough that it requires fiberglass insulation to carry a cancer warning label.
PINK FIBERGLASS LOOSEFILL/BLOWN-IN
Appropriate for both new build and remodeling projects, loose fill insulation molds into the shape of your wall cavity with complete compression and gap-free insulation coverage. This product provides superior performance using less material than other sources. It is high in R-value, can fit any cavity and is especially a favorite in attic spaces.
PINK FIBERGLASS BATT
Made-to-fit, pre-cut fiberglass batt insulation comes in a variety of sizes and R-values. It can be used on its own or in conjunction with other insulation solutions for even greater energy efficiency. Batts can be customized to fit your particular walls, floors and ceilings.
