Tallahassee Roofing: Article About Replacement Window Considerations For Florida Homeowners
Many Florida homeowners find that the local climate causes some unique problems in home energy consumption. By installing replacement windows with spectrally selective glazes, homeowners can enjoy bright sunny rooms that are also cool and comfortable. Many Tallahassee roofing companies are also certified to install replacement windows, and they are more than willing to assist homeowners in choosing the best windows for the home's architectural and energy needs.
The sun's energy is made up of more than just the light that we see. It is also composed of infrared energy (IR) and ultraviolet energy (UV). For a homeowner's purposes, infrared energy is responsible for transmitting heat. Ultraviolet light is responsible for the breakdown of fibers and fades upholstery and carpets. Certain replacement windows are able to combat these effects.
Modern replacement windows combine several technological advances to create windows that are energy efficient, functional and beautiful. The National Fenestration Rating Council has devised testing standards and labels windows with regard to their energy efficiency. The NFRC label tells customers how well a window resists the flow of heat from the sun into the home and how well it resists the flow of heating or cooling energy to the outside of the home. It also tells homeowners how much visible light will come through a particular type of glass. All of these things are important for Florida homeowners.
The Solar Heat Gain Coefficient (SGHC) is the number that describes how much a window will allow a room to be heated by the sun.
A roofing contractor from Art Construction of Tallahassee FL can answer your questions about insulation or doors.
The best windows will have an SGHC close to zero. The worst rating possible is 1. These windows have a special coating that reflects infrared energy away from the window while allowing visible light to pass through.
Windows are responsible for the majority of a home's' energy inefficiency. To combat this, modern windows have two or three panes of glass with an inert gas sandwiched between the panes. This configuration operates on the same principal as a thermos bottle and prevents the window from "leaking energy." A window's ability to keep warm rooms warm and cool rooms cool is called the U factor. The lower the U factor, the better, with 1.20 being the worst rating possible. Triple pane windows have a lower U factor than double pane windows.
Special coating can be added to a window's glass that filters out damaging UV rays while allowing visible light to enter. The windows that are most effective in this regard have the coating applied to the outward facing side of the second of three panes of glass. In most applications, this type of treatment may be considered overkill. However, in a sunroom, it may be necessary. Currently, NFRC labels do not give information regarding UV filtration.
