Horizontal Sliders


Horizontal sliders are one of the most versatile and commonly used designs within our Secondary Glazing product range

As with all our secondary glazing windows and designs, the horizontal slider is designed to improve the overall efficiency of your home. Perfect for improving heat loss issues in the home, reducing external noise or reducing the amount of condensation from your old windows.

The horizontal sliders can be manufactured in combinations of 2, 3, 4 and 5 panels and each of the individual glazed sashes can be removed for easy cleaning and maintenance of the existing window frame.
