Energy-Efficient Windows for Indianapolis, IN, Homeowners

Significant amounts of energy are lost through old, broken, and drafty windows, which can drive up heating and cooling costs. At L.J. Stone Company, Inc., we aim to help Indianapolis homeowners combat these issues with our high-performance, energy-efficient replacement windows. Designed to insulate your home and minimize heat transfer, our windows will help maintain a comfortable interior temperature so you can spend less time fidgeting with the thermostat and enjoy lower monthly energy bills.

A Guide to Energy Efficiency

energy efficient windowsWe always want our customers to be 100% satisfied when they turn to us for replacement windows. One way to ensure this is to discuss some of the many confusing terms that are associated with energy efficient windows, including:

  • U factor – This term is indicative of how easily heat energy can pass through a window. Windows with low U factors will typically insulate better than those with higher U factors.
  • Solar heat gain coefficient (SHGC) – The SHGC of a window indicates the amount of solar radiation that can pass through it. Windows with low SHGCs will more effectively block radiant heat from a home and keep it cooler. However, in cooler climates like ours, retaining some solar heat may be beneficial, especially during the winter months. We’ll help you decide which SHGC level will best meet your needs.
  • Visible transmittance (VT) – This term refers to how much visible light is transmitted through a window. Though a high VT will help maximize daylight in your home, it’s important to remember that the special coatings used on window glass to block UV and infrared light will diminish VT to a certain degree.

Now, let’s focus on the energy efficiency of the replacement windows from L.J. Stone. We proudly install these outstanding windows because they are chock-full of energy-saving features, including:

Would highly recommend LJ Stone!

“Excellent experience from beginning to end! They removed our old bathtub/shower surround and installed a new bathtub/shower with glass door and did a fantastic job. Looks even better than we imagined and has completely updated the look of our bathroom. High quality materials and a very rich look. Everyone was very friendly, professional, informative and kept us updated throughout the installation process. Would highly recommend LJ Stone!”

Sean D.

Great experience!

“LJ Stone came in and replaced our shower/bath with a new shower. The installer came in and to be honest, we hardly new they were here. It only took them a day and a half, and the next day I enjoyed a nice warm shower. What impressed me most was how clean they were in the process. For taking out an old tub, and doing a bit of drywall work there was virtually no cleaning we needed to do behind him. The only way you knew he had been here was the wonderful shower he left behind. Great experience!”

Rob H.

They were here for two days, were right on time, and did a fantastic job! I have always recommended LJ Stone, we had windows, siding, and a new bathroom installed in Greentown, IN by LJ Stone that’s why we keep coming back, great company and you back up your products!”
