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.
