Horizontal Sliding 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.

 

Each individual secondary glazing panel can be lifted up into the top of the outer frame and then swung inwards to facilitate removal. This allows access for cleaning and maintenance of the secondary double glazing.
