British Gypsum Gypframe Security Sheet has been specifically engineered and designed to provide added resistance to determined attacks when used within the cavity of the GypWall SECURE system. This includes a lightweight security wall in accordance with the BS 5234, some acoustic insulation, fire resistance and being able to install an additional steel sheet for added safety. The on-sight testing has shown that the system provides substantial protection from attacks using hand tools and a good barrier when using power tools. It has wide application including pharmacy and data storage rooms or cash desks.
