Flashing corners provide for transitional flashing: flashing from one geometric plane to another geometric plane.
Flashing corners may be used in many areas of a wall system. Parapet walls, electrical boxes and most commonly window pans.
Energy Star requires window pans under all windows to qualify as an Energy Star home. So Window pans are more important than ever before. Using Flashing Corners is the best way to create a window pan.
Lightning Flash Corners and Lightning Flash XL Corners are ideal for window pans. Lightning Flash Corners are smaller and designed for aluminum and vinyl windows. Lightning Flash XL corners are larger, and may be best under wood windows, commercial windows and doors. The GS 100 series is designed for recessed windows.
