ABSTRACT:
A system for protecting exterior building walls against damage from pressure waves generated by explosions on the building exterior. Exterior walls are constructed of multiple wall panels mounted in a circumferential framework of building elements formed by columns, a top surface of the floor below the wall and bottom surface of the floor above the wall. A series of guide tracks mounted in the circumferential surfaces extend perpendicular to the wall panel towards the interior of the building. Guide blocks on the perimeter of the wall panel engage the guide tracks so that the wall panel can slidably move along the tracks when a predetermined threshold force is applied to the exterior of the panel. An adjustable brake, on cooperating with the guide blocks and tracks, permits an accurate setting of the threshold force under which inward movement of the panel commences as well as the relatively constant force that acts during sliding.
