The process by which drop away panels work is as follows: Drop away panels are thin plastic panels which in turn have a low melting point. At 135 degrees the panels, which are framed by the Cool Shield Channel, will start to shrink at the edges. This causes the panels to fall to the ground. They are very light weight and pose no risk of injury. Most temperature activated fire suppressions systems activate at 150 to 175 degrees so the panels will be out of the way before a discharge. It is important to note that drop away panels are not smoke activated. We recommend checking with local fire inspectors prior to any purchase.
