The RG variant is absolutely hermetically sealed, as there are no joints on the inside. Another special feature is the ALU RG-TG guide rail system. This is a thermally insulated system that guarantees tightness between the guide rail and the window in rainy conditions.
The advantage of systems closed on the room side is, in addition to improved insulation properties, invisible integration on the room side. Since inspection is carried out from the outside, the box can be fully plastered on the inside.
