Roller shutters in PVC box – top-mounted

Under-plaster roller shutter is installed after montage of windows but before the building’s thermal insulation is made. It can be installed on the wall but it’s necessary to take the dimensions of the box into account when planning the insulation of the building. It’s important to provide insulation for the surface between the box and lintel. It’s required to properly prepare window holes so that box of the roller shutter is fully covered by insulation or plaster.
