How do I know if a window is energy efficient?

• <div><p>Energy-efficient windows are judged on their performance according to a few different factors, including heat transfer, air leakage, light transference, and condensation resistance. If you're unsure whether a window is energy-efficient, look for an ENERGY STAR® label from the <a href="https://www.energystar.gov/">U.S. Environmental Protection Agency (EPA)</a>. If various products, including windows, meet energy-efficiency standards set by the federal government, the EPA issues this label to help consumers identify energy-efficient products.</p></div>

Do bow windows need support?

• <div><p>Bow windows need support because they are large and extend out from the exterior wall of the home. Bow windows may extend 1 foot to several feet from the outside of the home, so you’ll need to provide additional support to handle this weight. A window contractor will be able to provide the proper amount of support for your new bow window.</p></div>

Q: How do I maintain clean business windows?

• <div><p>Regular cleaning, non-abrasive cleaners, and scheduling professional services every few months help maintain clarity and shine.</p></div>

Q: How do bifold windows work?

• <div><p>Bifold windows work by using a track that allows panels to slide to the side and &quot;stack&quot; so they take up minimal space, leaving the largest opening. The sashes connect to each other with butt hinges or concealed hinges and to the window frame with the same type of hinges you&rsquo;d find on a casement window. Some manual bifold windows also have casement stays or another piece of hardware to keep your windows in place when they&rsquo;re open.</p></div>

Q: What is the difference between an awning window and a hopper window?

• <div><p>Awning windows are just like hopper windows except that they open the opposite way. Instead of opening inward, awning windows open outward with a hinge at the top. This creates a mini-awning within your window frame, which is where the name comes from. Hopper windows, on the other hand, open inward with a hinge at the bottom.</p></div>
