A89LS - Aluminum Lift & Slide Doors
Smooth & silent slide action operation
The A89LS aluminum door system is an ideal solution for connecting interior space rooms with the outside balcony, terrace or garden area. Providing both a smooth & silent slide action operation, it can bring the benefits of a beautiful day outside, into the living space.
By the way of its design & operation, the A89LS is a great space saving opening & does not encroach the free space beyond the internal or external confines of the frame, without any compromise. Available in two different options, with regard to the level of thermal performance, standard or highly insulated.
The design & arrangement of the system profiles enable luxurious openings of large dimensions, accommodating double & even triple glass unit compositions, which in conjunction with the constituent parts & innovative technical solutions, help achieve a high level of thermal & acoustic performance.
