Single Hung Window

  • T520

The T520 is a single hung window with the lower sash being operable and lifts up with the upper sash always being fixed. This window utilizes Iso bar technology which achieves a high level of performance when it comes to reducing the amount of hot and cold transfer from the exterior to the interior of your home. This combined with high performance 1” Low-e insulated glazing that gives a “one two punch” against the elements.
