Aluminium awning windows have a pleasant slimline architectural appearance, which make them one of the more discreet window types available. Often chosen because of their functioinal design, awning windows are ideal in situations where furniture or kitchen benches prevent easy access to the window. The unique chain winder allows easy operation without interfering with insect/fly or security screens. Another feature of the awning window is that it can be left partly open during inclement weather to allow continuous ventilation, while at the same time not letting in any of nature's undesirable elements.
