Energy Efficient Windows for Nashville Homes

Our energy efficient windows at The Window Source of Nashville are designed to withstand extreme heat and cold while also providing four-season comfort and energy savings. This keeps your house warm or cool while also saving you money throughout the course of the windows’ lifetime.

Want proof? In addition to meeting or exceeding the requirements for ENERGY STAR® Version 6.0 in all 50 states, we also surpass those for the Northern Zone by up to 48% with certain glass packages. Below are four common ratings that are provided for windows certified by the National Fenestration Rating Council (NFRC):

  • U-Factor – A measure of the rate of heat flow through a window. A lower U-Factor indicates a higher performing window that can help reduce heating and cooling costs.
  • Solar Heat Gain Coefficient (SHGC) – The amount of solar radiation allowed to pass through a window. The lower the number, the less solar heat gain and UV rays the window permits to enter.
  • Visible Light Transmittance (VT) – Ranging from 0 – 1, visible transmittance is a measure of how much light passes through the window. The higher the number, the more light that can pass through.
  • Condensation Rating (CR) – CR measures how well a window resists the formation of condensation on the inside surface. CR is expressed as a number between 1 – 100.The higher the number, the better a product is able to resist condensation.

The Window Source team replaced all the windows in our home. Not only do they look beautiful but our home is less drafty and was warmer this winter.
