Abstract: An opening in a building wall is closed by a building closure such as a window or door. A mounting part of the closure arrangement is received in a space between two countersupport surfaces formed by a U-channel or opposite L-members that protrude perpendicularly from the sill or jamb surface of the wall bounding the opening. Mounting brackets secure the U-channel or L-members to the wall. On one or both sides, a respective damping element is interposed between the mounting part and the respective adjacent countersupport surface. The damping element may be a plastically deformable metal strip. When an explosion force acts on the closure arrangement, the damping element is first plastically deformed to absorb energy, before the remaining force is transmitted into the building wall. The two damping elements on opposite sides damp forces from the positive and negative pressure waves of the explosion.
