Additions, ADUs and garage conversions in the valley usually mean stucco walls, so nail-fin windows have to be flashed before the stucco goes on. The energy forms set the U-factor and SHGC the windows need.
New construction windows have a nailing fin around the frame and are set into open framing before the siding or stucco goes on. They are used in new homes, additions, garage conversions and ADUs, and when a full-frame replacement takes a wall down to the studs. The fin is lapped with building paper and flashing so water runs out, not in.
In the valley, the wall around the window is usually stucco, and the order of work matters. The window is set and flashed, the stucco crew laps its paper over the fin, and only then does the stucco go on. If that order is wrong, water can get behind the stucco at the corners. We work with your builder's schedule.
Windows for new construction must meet the California energy code like any others, and the builder's energy compliance documents list the U-factor and SHGC the windows need. Bedrooms need egress windows big enough to climb out of, and glass near doors, tubs and floors may need to be tempered. We check the plans and measure the rough openings before anything is ordered.
