Restraint Straps and Banding - Types and Application


Where floors, joists, rafters and flat roof trusses are built in or supported by hangers off the wall, its required to use lateral restraint by tension straps in accordance with the provisions in BS EN 1996-2:2006 and Building Regulation requirements. Lateral restraint straps are required at floor, rafter or flat roof member levels and in pitched roofs at ceiling joist levels. The masonry walls would also benefit from the lateral restraint by restricting movement of the separating walls and gable walls.
