Unless your home was specially constructed for energy efficiency, you can probably reduce your energy bills by adding more insulation. Insulation in housing building provides resistance to heat flow. That means the more heat flow resistance your insulation provides, you’ll get lower costs.
Insulation comes in a variety of forms. Choosing the best insulation for the building can be tricky. You may want to consider the insulation that works best for you in terms of value. These considerations may include indoor air quality impacts, life cycle cost, recycled content, embodied energy and ease of installation.
Fiberglass insulation is a fiber material made from recycled glass which cuts down on the need for fresh resources of sand and glass. Fiberglass is one of the “green materials” that helps to reduce the amount of energy that goes into keeping a building warm or cool, thus lessening emissions from fossil fuels that are burned to generate electricity or heat. Due to its composition, fiberglass is known for its very low embodied energy with the total energy required to produce a product from the raw materials stage through delivery of fiberglass products.
Fiberglass insulation is available in several forms. Fiberglass is a lightweight fiber that can be blown into open spaces such as attics, or be installed in batt form, usually between studs, joists or rafters.
