Full Product Description


The Product

The Horizontal Slider is undoubtedly the most frequently used type of secondary glazing. Its uses are therefore widespread, being applied to high rise or low-level commercial properties, historic buildings as well as all kinds of domestic dwellings. Our solutions provides sensitive solutions to the problems created by noise and sound pollution.

How it Works

Generally available in two, three or four paneled versions. The secondary glazing panels are fitted with brass rollers, ensuring the smoothest sliding action. Twin brush seals provide excellent high sealing efficiency. This has been scientifically proven to eliminate draughts, increase thermal insulation and give greater improvements to the security of the primary windows. The security issue is further enhanced with the use of the latest locks and handles.

In 2 and 4 panel horizontal sliders, all of the secondary glazing panels are able to move. 3 panel horizontal sliders are available in systems where all secondary glazing panels move (CO3), or a single pane can be fixed (SS3)
