When shopping for replacement windows, it’s important for you to look beyond buzzwords like “energy-efficient” or “eco-friendly.” Verify those kinds of claims and make sure you’re really getting a window that meets your needs.
Renewal by Andersen® of Rapid City, a local expert in awning windows installation, shares this simple guide to choosing the right energy-efficient window for your home.
ENERGY STAR® Rating
Check the ENERGY STAR label as this can give you all the information you need in determining a window’s capacity for energy efficiency. Look for the ENERGY STAR rating and, more specifically, the U-factor and Solar Heat Gain Coefficient (SHGC).
U-factor is the amount of non-solar heat that escapes through the window. Meanwhile, SHGC is the measure of how much solar heat passes through the window.
Frames
Various materials can be used for window frames. Some of the popular choices include wood, vinyl, composite, and aluminum. Naturally, these materials have different rates of heat transfer, and some may be more suited to particular climates. Ask your local window contractor regarding the best options for your region.
Glazing
Whether you’re planning for a double-hung or casement window replacement, you should know all your options when it comes to window glazing. The most common types of glazing are gas fills, low-E coatings, reflective coatings and heat-absorbing tints.
Gas fills, which fills the space between glass panes with inert gases like argon or krypton, is often used in regions with colder climates. Low-e coatings, while costing a bit more than regular windows, can help reduce your energy loss by 30-50%. Reflective coatings can significantly cut down a window’s SHGC, so it’s commonly used in hot climates. Heat-absorbing tints usually come in gray or bronze tints, which help reduce the sun’s heat and glare. Blue and green tints, however, allow more penetration of natural light.
