When installing the frame, it is necessary to take into account the thickness of the insulation bags and choose the thickness of the rails in proportion to the thickness of the bags, so that after installing the packages on the surface you can apply facing material and strengthen it to the frame. To protect mineral insulation from moisture, insulation bags are installed on the waterproofing film, which is installed in each cell of the frame. Also, soft fibrous heaters need to be protected from moisture of the room. To do this, cover a layer of insulation with a vapor barrier film before lining.
