REBATES OF FRAME TO WALL
The perimeter profile of the frame can be chosen by the customer based on his preferences and does not affect the price. It is possible to choose different types for each side. Types of profiles: “L” – “Z” – “T” see drawings.
TYPES OF WALL AND RELATED FASTENING SYSTEMS
The sub-frame is not mandatory, is optional. These fire rated shutters can be installed directly to the masonry wall using dowels with subsequent sealing of the gaps. Or with screws on certified fire-rated plasterboard or calcium silicate partitions (called flexible by the standard) or on certified metal structures insulated with rock wool and protected with a double or triple layer of plasterboard.
Below the schematic representations of the main types of fastenings.
