About the Integrity Wood-Ultrex 3-Wide Double Hung Window

The Integrity Wood-Ultrex 3-Wide Double Hung Window features three double hung windows, that when jointed together can impressively open up your room to the outside light. This mulled window's appearance is reminiscent of a traditional colonial style, but it has all the durability of a top of the line modern window.

As with all Integrity Wood Ultrex windows, this 3-wide double hung option has a durable, long lasting ultrex exterior that is as strong as steel and is virtually indestructible. The Ultrex exterior meets a solid pine interior that provides classic beauty and natural insulation. The structural integrity of this window is just as impressive as its asthenic beauty.

  • Impressive 3-wide mulled window joined together in one impressive unit
  • The top and bottom sash tilt and remove for user friendliness and allow the window to be easily cleaned and maintained
  • Reliable locking system that ensures the user's security
  • Multiple screen options

The lower the number, the more it will help reduce the use of air conditioning and energy use. In cold climates, a higher SHGC is desirable to collect heat from sunlight. SHGC typically ranges from 0.25 to 0.80.
