Flame protection cover for ERT rubber expansion joints, made of several layers of glass fiber fabric with a surface cover of silver- coloured high temperature resistant silicone aluminum -glass fabric. Screw, nuts and washers of brass. It reliably protects the expansion joint against radiation heat and direct flames up to 800 C for 30 minutes. The flame protection cover is resistant against oil and chemical influences as well as against ageing and weathering. Because of its split design the flame protection cover can be mounted subsequently or re-opened. The dimensions have been chosen in such a way that also the counter flanges are completely covered. The allowed range of movement is not restricted.
