Abstract: A solar panel assembly including a solar panel spaced from a surface to create a gap and a barrier movable between an open position and a closed position, the barrier being adapted to inhibit airflow through said gap below said solar panel when in the closed position. The assembly may further include a rack supporting the solar panel and resting on the surface. The barrier may be adapted to move from the open position to the closed position upon detection of conditions indicative of a fire. In this way air flow below the solar panel is permitted during normal operation of the solar panel assembly but is inhibited upon detection of a fire.

Abstract: A flexible covering product is provided comprising a foil layer having first and second major surfaces, a protective membrane adhered to the first major surface of the foil layer, and a pressure sensitive adhesive on at least a portion of the second major surface of the foil layer in a quantity sufficient to adhere a majority of the flexible covering product to a building structure. The adhesive is preferably covered prior to application to a building structure with a release liner. Methods of use of this flexible covering product are also described.
