  • Sliding Patio Door and Frameless Corner Window Replacement
    Sliding Patio Door and Frameless Corner Window Replacement

    We were hired to replace an older aluminum sliding patio door and a frameless corner window in the kitchen. Frameless corner windows are beautiful, but they are single pane and this home is in the Palm Springs area, where heat is a huge issue. This homeowner wanted to increase the energy efficiency of her home with her replacement windows. In order to achieve this, we installed a post at the corner and used Milgard Tuscany Series Windows with SunCoat Max and Argon for heat control. It turned out beautifully and now she has beautiful replacement windows that are also energy efficient!
