EXTECH's TECHVENT 5300 is a patented top-hinged industrial polycarbonate windows system that is designed to stay open during normal rainfall while keeping the interior dry. It provides massive natural lighting and ventilation and is great for new construction or retrofit work.
It can be operated either manually or electrically with an optional control system available, and it is available with thermally broken framing.
The TECHVENT 5300 is a very versatile system that can be installed in an individual punched opening or in continuous clerestory wings.
