Why Choose Our Green Energy Window?

Our windows are designed, developed, and engineered exclusively for Green Energy of San Antonio. You can’t get their superior features and benefits anywhere else.

Green Energy Windows

  • Cost – Our windows offer superior home energy efficiency in all regions of the country, but especially in Texas. When you replace a single-pane, clear glass window with our superior windows, you get an immediate return on your investment with dramatically lower energy bills. 
  • Efficiency – Green Energy Windows keep your house warmer in the winter and cooler in the summer. Our high-quality vinyl is a thousand times less thermally conductive than aluminum. This makes it prevent far more heat coming in during summer and heat going out during winter. 
  • Appearance – Green Energy Windows are gorgeous. Installing our windows will immediately upgrade the look of your house. 
  • Durability & Safety – When we say that our windows don’t break easily, we mean it. The three layers of double strength glass will take more than just a hammer to shatter them. Green Energy Windows last longer and keep you and your family safer. 
  • Upkeep Made with maintenance-free vinyl surfaces, our windows are incredibly easy to clean. The high-quality vinyl won’t pit, peel, or flake, and it stands up to harsh weather year after year. The occasional washing keeps them clean and beautiful, like new.

Traditional Windows

  • Cost – The amount you save when you purchase standard windows, you lose on your energy bills and when you sell your house. You get up to 80% of what you pay for Green Energy Windows back when you resell them, on top of your energy bill savings.  
  • Efficiency – Most houses come installed with aluminum-framed windows. As you may know, aluminum is an excellent thermal energy conductor. Unfortunately, this makes it a horrible material for energy efficiency.  
  • Appearance – Ordinary windows are just that: ordinary. No one is going to take notice of them, and they don’t add any curb appeal to your home.  
  • Durability & Safety – Single-pane windows break incredibly easy. Thieves looking to break into your home through a window will have no problem. Even if you take good care of windows with a wooden frame, they will eventually begin to warp.  
  • Upkeep – With wooden windows, you have to sand, repair, and repaint them year after year. Even then, they don’t age well.

“I would suggest [Green Energy of San Antonio] to anyone thinking of doing their windows. The company had the windows ready earlier than promised & installed all 6 in just a few hours. I’ve gotten many compliments on them and the house actually looks almost modern. The way they keep out sound & hot/cold is amazing. Definitely worth the money!!”
