Aluminium Secondary Glazing
Our Horizontal Sliding Secondary Glazing is extremely versatile, slides smoothly and is available with two to five panels. Horizontal sliders are perfect for sound and thermal insulation for casement windows, hinged windows, or any window that has vertical bars. Panels slide within the frame allowing easy access to the existing outer windows, providing ventilation without interfering with curtains or blinds.
Horizontal Sliders are available in our Economy Odd Leg, Luxury Subframe and Heavy Duty systems. Units can be linked with coupling sections allowing both large and ribbon windows to be successfully treated.
