A59LS gives you great possibilities in applications of lift & slide doors, and is the optimized solutions in terms of construction and dimensions of its profiles and frames. With its high thermal and sound insulation, combined with excellent water and air tightness, A59LS meets all the requirements for energy conservation and environmental protection.

  • Key features
  • Technical Specifications
  • Performance
  • important dimensions of the door leaves that exceed by far any standard values: height up to 2.8 m, width up to 3.3 m; and max. leaf weight up to 300 kg
  • slender and robust, 3-chambered profiles, with insulating chamber equipped with wide thermal breaks in the central part,
  • 2-or 3-rail frames that enable the fabrication of doors with wide clear passage size
  • large glass thickness to be fitted in the door leaves (up to 42 mm) to bring flexibility in choosing the appropriate glass
  • fixed lites can be fabricated with glass mounted directly to the frame – a solution that is both aesthetic and economical
  • relatively low heat transfer coefficient for frames (Uf) assured by wide thermal breaks, polyethylene inserts and chambered profiles mounted in thermal insulation strips
  • high water and air tightness assured by specially-shaped gaskets and hardware that allow the leaf to embed on the frame in the final stage of closing the leaf
  • ability to mount most of the hardware for lift & slide doors available on the market
  • door version with a low-level threshold, which makes it easier to use the door especially by the elderly or disabled
  • doors can be mounted individually or as part of larger constructions: mullion and transom curtain walls or winter gardens
  • maximally simplified construction technology to reduce time and costs of fabrication
  • compatibility with other Ecowindows systems – common components can be used

We offer high variety of Aluminum windows and doors. Every order is custom made according to our customers requirements. Our modern construction solutions make it possible to create extremely large g lazed areas and improve building design and interior décor not available with most of our competitors, for example 25’ W x 9’H lift and slide doors. We have almost an unlimited potential in terms of both colors and their different shades for our aluminium components. Another key benefit for our products are the components utilizing multi point locking. This is achieved through a link gear running around the window sash, which operates pins which in turn lock into keepers located around the perimeter of the sash opening. Depending on the size of sash used, there can be up to twelve locking points on any one sash. In doors a six-point lock is used. This comprises of four compression roller pins, one latch and one dead bolt. All the locks on any one sash are operated by one lever and secured by one key. Further this creates insulating advantage as an even sash seal is achieved as well as enhanced security. Pleae note we can perform the installation or assit our customer in an installation consult capacity.
