Buying Your Custom Windows August 7, 2013 When you need to replace old windows you have to pay attention to more than just the glass and frame. If your windows are irregular your openings may need to be altered to fit new ones. This could mean a choice between altering the openings or buying custom windows. Energy efficiency upgrades or stricter building codes may dictate which models you can choose from. Review all your options and compare costs before deciding to go custom. There are other reasons to consider going custom other than the sizing of your windows. If you’re buying windows that better compliment the style of your house you’ll have more options in terms of size and shape with custom work. Upgrading to energy-efficient models is another great reason to opt for custom windows, especially if you are replacing a treasured signature window like a bow or bay. Custom ordering allows you to determine the features and measurements you need. You want to choose the best glass for your climate and region – energy efficient glass comes with different options. You’ll also need to decide what material you want – vinyl, aluminum, wood, fiberglass, etc. There are other options as well – coating, gas, light transmittance, impact resistance, and more. Your choices should be based on where you live and what sort of weather you regularly deal with. Also, ask about the warranty: Most companies provide the same warranty on their custom windows as on their standard ones. The custom windows should also maintain the same performance ratings assigned by industry groups as the standard products. Once you’ve weighed your options and chosen to go with custom windows you have a few other options to consider. If your frames are in good shape you might not have to replace the entire window, just the glass. This could be a money-saving option that will also let you keep your existing look. You might be able to just order custom panes, unless they’re glued into the frame or you want to upgrade to a thicker glass. You can also order a custom replacement window, which is a new unit held together with a thin frame that’s inserted into the existing frame. The most expensive option is replacing the entire unit with a new window, including the frame, sash, and trims. Unless you have previous experience measuring and installing you want to hire a professional to help you before ordering your custom windows. It’s best to also let the professionals do the installation. You can have the best, most expensive custom windows, but you will have wasted your money if they leak air or water, so make sure to have them professionally measured and installed.
