Cool Roofs
Email:
Description :Save money. Stay cool. Lowering the temperature of buildings and homes can be easy. A cool roof is one that has been designed to reflect more sunlight and absorb less heat than a standard roof. Cool roofs can be made of a highly reflective type of paint, a sheet covering, or highly reflective tiles or shingles.
Nearly any type of building can benefit from a cool roof, but consider the climate and other factors before deciding to install one.Just as wearing light-colored clothing can help keep you cool on a sunny day, cool roofs material that is designed to reflect more sunlight and absorb less heat than a standard roof. Standard or dark roofs can reach temperatures of 150°F or more in the summer sun. A cool roof under the same conditions could stay more than 50°F cooler and save energy and money by using less air conditioning.
Benefits of Cool Roofs
A cool roof can benefit a building and its occupants by:
Reducing energy bills by decreasing air conditioning needs
Improving indoor comfort for spaces that are not air conditioned, such as garages or covered patios
Decreasing roof temperature, which may extend roof service life.
Beyond the building itself, cool roofs can also benefit the environment, especially when many buildings in a community have them. Cool roofs can:
Reduce local air temperatures (sometimes referred to as the urban heat island effect)
Lower peak electricity demand, which can help prevent power outages
Reduce power plant emissions, including carbon dioxide, sulfur dioxide, nitrous oxides, and mercury, by reducing cooling energy use in buildings.
