Although there are numerous ways to increase energy savings in your home, replacement windows can produce an immediate and substantial utilities cost reduction. While beautifully enhancing the interior and exterior appearance of the property, this home improvement offers superior climate control for?increased comfort and home resale value.
According to the EPA, substituting outdated, single panes with energy efficient, home replacement windows can save homeowners up to $35.00 per month on utility bills, and some local utility companies also offer substantial rebates on windows with certain environmentally approved ratings. There are also a number of qualifying tax incentives for homeowners who make the upgrade with home replacement windows.
R-Value and U-factor Ratings
Because of improved standards, most window manufacturers that construct home replacement windows, provide energy efficiency ratings for each product. This may include an R-value, or a U-factor, depending on the maker.
An R-value measures the thermal resistance of home replacement windows. Essentially, how easy it is for heat to pass through the substance. The number value indicates how resistant the window is to heat loss, the higher the value, the more energy efficient.
However, the U-factor indicates the level of heat transfer, factoring in the solar energy created by sunlight passing through, combined with the effects of wind, and indoor and outdoor temperatures. Most new home replacement windows incorporate this rating, a lower?value indicates the best insular quality.
Optional Ratings
VT Level ? Window glass can be treated to allow or hinder sunlight. The VT level measures the amount of light that will be visibly transmitted through the home replacement windows. The higher the VT rating, the more light that can enter the room; thus, requiring less electricity during daylight hours.
Solar Heat Gain Coefficient ? Similar to a greenhouse, light entering your home becomes heat when passing through certain materials, including windows. The SHGC indicates how much of the light will be converted to heat. The lower the value, the better the home replacement windows will prevent temperature fluctuations caused by sunlight.
Air Leakage ? This rating calculates the amount of air that can pass through the window frame area, using a cubic feet ratio formula. The stronger the seal and the less air infiltration, the lower the value.
Gas Fill Options
New home replacement windows can be purchased with chemical fills between panes, designed to increase energy efficiency ratings. Certain gases have properties that act as an invisible barrier that can reduce conduction and heat transfer.
Inert Argon and Krypton gases are denser than air and provide superior heat flow prevention. When suspended between the panes, these odorless, non-toxic gases form a barrier that improves the window?s performance.
Due to innovative advancements in window design, increasing energy savings in your home can be as simple as choosing new home replacement windows. The substantial value, beauty, and comfort will enhance your living space and produce lasting effects by providing a sound investment and helping conserve our world?s energy resources.
