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.
