One of the most effective ways property owners can save money on heating and cooling costs throughout the year is by making sure the building has enough insulation. Insulation plays a key role in minimizing heat loss that occurs through the roof and walls of the building. A qualified Atlanta roofer can evaluate commercial and residential buildings to determine if they have the proper amount of insulation.
The laws of thermodynamics dictate that warm air will naturally flow toward cooler areas. This means the cool air from an air conditioned building in the summer will attempt to flow outside. When the temperature drops outdoors, cool air from outside will try to flow toward the heated air inside.
The insulation's density, type of material and thickness determines its level of resistance. The industry measures the resistance by a standard called the R-value. The higher the thermal resistance of an insulation product, the higher its R-value will be.
The US Department of Energy is responsible for setting R-value standards for buildings all across the country. Climate is one of the biggest factors involved in assigning the proper R-value. Buildings in regions with extremely high or low temperatures require insulation with a higher resistance to heat.
Very few attics are heated or cooled and many lack sufficient ventilation. This makes this portion of the building the least energy efficient. When the temperature falls during the winter months, the attic is usually as cold as the air outdoors. When the temperature rises during the hot months, that attic may be as much as 40 degrees hotter. The best way to control heat loss is to install enough insulation.
A reputable roofing contractor has the knowledge and tools to determine if a building's insulation meets the current standards. Because the DOE adjusts the standards occasionally, an older building may not have as much insulation as it needs. Adding more is a relatively simple process that pays for itself with lower energy costs year round.
The heating and cooling system does not have to work as hard in a building with the correct amount of insulation. In addition to lowering monthly energy bills, ensuring the insulation meets current standards can extend the lifespan of the heating and cooling system saving the building owner the expense of premature replacement. There are many types of insulation but the three most common are fiberglass, cellulose, and foam. An experienced roofer can outline the advantages and disadvantages of each type to assist the consumer in making an informed purchasing decision.
