SL 35 bi-folding door
This non-insulated system is ideal for your terrace, balcony, swimming pool, outdoor kitchen and as an indoor partition
Some projects are suited to the use of non-insulated bi-folding doors. The SL 35 can be used as balcony glazing, as glazing for under glass canopies, swimming pools and outdoor kitchens, or in any situation where thermal insulation is not important such as internal partitions.
The SL 35 is also perfect for commercial uses such as kiosks, outdoor restaurant areas, office partitions and as balcony glazing for non-insulated facades.
The SL 35 can be designed to fold outwards, inward, to the left and/or to the right, depending on your needs. Thanks to their cutting-edge technology, these systems are incredibly easy to operate and the outer panels can be cleaned conveniently from the inside by simply pulling out the hinge pins.
