Horizontal Sliding Aluminium Secondary Glazing

Horizontal Sliding 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 & provide ventilation without interfering with curtains or blinds.

Horizontal Sliders are available in our Economy Odd Leg, Slim-line Equal Leg, Luxury Subframe and Heavy Duty systems. Units can be joined with coupling sections allowing both large and ribbon windows to be successfully treated.
