Windows and doors are most concerned about performance. After all, a window or door that isn’t performing up to par means that energy is leaking out and because of this you could literally be sending money out of the window. Luckily for homeowners, the National Fenestration Rating Council provides ratings on all types of Energy Star windows. Companies that manufacture doors and windows aren’t required to use these rating systems, but many of them do. Before you purchase a new window or even door, learn about what these types of ratings mean.
Understanding The U-Factor
The U-factor is the rate that a window, door or perhaps skylight conducts non-solar heat flow. Just like in golf, a lower number is better — a lower quantity designates a higher level of energy efficiency. One thing to consider when comparing U-factors is whether it is covering the entire window or maybe door or just the glass. However , if you’re getting the U-factor from the Nationwide Fenestration Ranking Council, and not the manufacturer, you can be sure that the rating covers the frame and spacer material, as well as the glass.
Understanding Solar Heat Gain Coefficient
Another rating to consider is the solar temperature gain coefficient. This measures the solar radiation that is released into the home. The lower the photo voltaic heat gain coefficient, the actual less warmth is released, which is ideal for climates that are warm most of the year. On the other hand, a high solar power heat obtain coefficient means that the windowpane will help keep a house warm in the winter and in cold climates. There is no one perfect sun heat acquire coefficient for all climates so you should choose the right 1 based on where you live, as well as the orientation of the wall.
How Companies That Install Windows And Doors Can Help
If you’re not sure what type of windows or door is right for your home, work with a company which installs them. They’ll be able to help you choose the right one for each exterior surface of your home. A wall that will faces west might require a very different type of window than one that faces north, so make sure to consider the orientation and any shading done by large trees as well as other landscaping.
While the ratings are important, these kinds of ratings won’t matter at all if the doors are installed incorrectly. Look for a company that is experienced in installing them correctly and professionally. When interviewing companies, ask what type of warranty they offer — the standard guarantee from the manufacturer isn’t enough. To make sure you’re working with a qualified company, ask them what additional warranties they offer to their customers. Some will not offer anything additional, but some will offer up to a five-year warrantee on labor. Your manufacturer’s warranty isn’t valid if the installation is done incorrectly so it’s vitally important that your windows and doors are installed perfectly the first time.
