Standard Vertical Sliders
Combining cutting edge technology without losing the traditional authentic box sash character and style. The vertical slider has the strength and durability of the old timber box sash and incorporates all the classic features like Georgian bars, decorative horns and deep bottom rails. Not only do the sashes slide but they can also be tilted inwards for ease of cleaning and extra ventilation. Both top and bottom sashes can also be fully removed from the inside, ideal for maintenance, installation or access.
