The A & R Progetti showcases are designed to minimize the risk of robbery and vandalism. The glasses used in the display cases are extra clear, to guarantee the best transparency index. The compliance with the safety requirements against anthropic damage can be modulated according to the PVB layers that make up the laminated glass according to UNI 7172, 9186 and 9187 standards, and is determined by our technical study according to the client’s requirements and specific requirements of the exhibit. of the architectural context. Our showcases can be certified according to the requirements of resistance to burglary, respecting the classification of the EN 1627 standard.
The structure, the anchoring systems of the exhibit and the window opening mechanisms are designed to ensure maximum stability and minimize stress related to gravity, impact and natural or anthropic movements. The engineering of the opening systems ensures smooth and slow movements to avoid vibrations or dynamic stresses to the structure that can be transmitted to the finds. The structures are equipped with adjustable anti-vibration feet for the absorption of vibrations coming from earthquakes, road or underground traffic.
The anchoring systems of the finds are studied according to the state of preservation: they ensure a correct exhibition layout and the minimum visual interference with the finds, avoiding specific stresses or obstacles to the natural settling movements of the constituent materials. The contact points between the exhibit and the support are made of “pad” materials such as silicone foam, cork, felt or polyethylene free of volatile acid emissions. In order to prevent possible electrolysis phenomena, in particular contacts between metal support and a different metal or alloy article are avoided.
