Series 278
Single Hung
Tempco’s Series 278 Single Hung Window. This new, narrow frame family of products has many of the features found in the older, wider frame designs. All welded frame and sash, multi-hollow profiles, wide interlocks and dual weatherstripping at the meeting rails combine to provide outstanding performance. The head jamb doubles as a picture window. The addition of a transom/bendable picture window and T-mullion provides flexibility. You can choose from a wide selection of shapes and styles to give a distinct personality and look to your home.
