  • SmartSun™ Glass

    SmartSun™ glass gives you the benefits of Low-E glass, plus it helps shield your home from the sun's heat by filtering out harmful UV rays.

    Ideal for: All Climates

    SmartSun™ with HeatLock Coating is also available on 100 Series windows. This prevents more heat from escaping your home but slightly reduces the visible light transmitted through the glass. 

  • Low-E Glass

    Low-E Glass reflects heat in the summer and helps to retain interior heat in the winter. 

    Ideal for: All Climates

    Low-E with HeatLock Coating is also available on 100 Series windows. This improves the U-Factor performance of the window but slightly reduces how much light comes through the glass. 

  • Sun Glass

    Sun glass has excellent thermal performance. This glass has a subtle tint that blocks out more heat from the sun.

    Ideal for: Southern Climates

  • Clear Dual-Pane Glass

    Clear dual-pane glass, which offers basic thermal performance, is in situations where codes allow its use. In North Texas, clear-dual pane glass does not meet energy code.

    See local code official for requirements in your area.


  • HeatLock® Technology

    HeatLock® coating reflects heat that likes to escape your home through window glass. It can be added to most of Andersen's glass options.

Decorative and Specialty Glass

  • Safety Glass
    Tempered safety glass is available on all products, and comes standard on all patio doors.

    Sound-Reducing Glass
    This glass helps reduce the volume of outside noise.  Available with Low-E, SmartSun and HeatLock coatings.

    Patterned Glass
    Let in light while obscuring vision and adding a unique decorative touch to your home. 


Screen Options

  • Illustrations of insect screens on casement and hung windows.

    Insect Screens

    For casement and awning windows, frames are available in White or Sandtone. For single-hung and gliding windows, stainless steel springs hold the insect screen tightly to the window frame and their frames are available in colors to match the product exteriors. Insect screens have gray fiberglass screen mesh.

  • Image of casement windows with insect screens.


    Optional TruScene® insect screens are made with a micro-fine stainless steel mesh, providing 50% more clarity than our conventional insect screens for a beautiful unobstructed view. They allow more fresh air and sunlight in, while doing a better job of keeping out small insects.
