With the steady increase in the prices of commodities and utility bills, many people are looking for ways to save some dollars. What some homeowners may not be aware of, is that they can incur huge savings from installing energy-efficient windows.
The U.S. Department of Energy has determined that inefficient windows are the culprit behind energy loss of 30% or more in a home. Installing energy-efficient windows that conform to standards set by the National Fenestration Rating Council (NFRC) can reduce energy use, along with your monthly energy bills. High Point roofing and replacement doors and windows expert ABC Roofing & Exteriors, helps you determine the efficiency of your windows per NFRC.
How Efficient Are Your Windows?
The NFRC is an independent, not-for-profit organization that sets the only nationally accepted rating system that vets the energy performance of windows, doors, and skylights. With these fair, accurate, and reliable energy performance ratings, builders, code officials, contractors, and homeowners can compare products and make informed choices.
How Can You Measure Your Windows’ Efficiency?
The U-value is the rate by which heat flows through a window. The lower the U-value, the more energy-efficient a window is. U-value measures the entire window unit, thus, it is the only measurement accepted by the U.S. Department of Energy’s ENERGY STAR program.
Meanwhile, R-value measures the resistance of glass to the heat flow. The higher the R-value, the better the insulating properties of the glass. R-value, though, does not measure the overall window unit, and therefore is not an accepted form of measurement by the NFRC or ENERGY STAR.
Finally, Solar Heat Gain Coefficient (SHGC) determines if a product blocks a significant amount of heat caused by sunlight. A lower solar heat gain coefficient means that the window transmits less solar heat.
How Can You Get Energy-Efficient Glass?
Apart from top-grade roofing in Winston-Salem, NC, we offer installation windows made with ow emissivity glass. Low-E glass reduces the amount of heat that enters and escapes a home, increasing efficiency. Through microscopically thin layers of oxidized metal applied to the glass surface, most heat energy is reflected back to its source as filtered light passes through.
