Built into every Sun product is a weep system that allows water to drain out of the product exterior. This prevents damage from water that might otherwise become trapped within the frame, sash or panel.
Sash & Frame Weep System
Any water that might happen to penetrate around the glass is drained to the exterior through the sash & frame weep system.
Fixed Lite Weep System
Fixed lites have weep slots that allow water to drain.
