Whatever Sunroom model you choose (S.75 TT, S.60 TT, S.40, or S.30), the frame is made of extruded aluminium, available in the thermal break or non-thermal version. Depending on your needs, all Sunroom folding doors can be packed inward or outward, on the right or left, or distributed on both sides for larger openings. The packing mechanism is very simple and is made with hinges and tracks that allow the panels to be packed next to each other so they almost disappear, creating a pack of overlapping panels to offer the maximum opening. The minimum footprint is one of the benefits of the Sunroom folding door systems and is a detail that should not be underestimated when choosing your glass system. When the panels are extended, on the other hand, the folding door will be hermetically sealed like a traditional glazed unit.
