Vertical Sliders

Smooth sliding uPVC sash windows

uPVC vertical sliders are the perfect combination of traditional design and modern performance. They work just like a traditional sliding sash window with the window sliding open wide to provide maximum levels of ventilation. Our sliding sash windows also feature a range of realistic heritage detailing. From traditional style hardware to run-through sash horns and authentic timer-effect woodgrain finishes, they tastefully replicate the classic aesthetic of sliding sash windows that were used in the 19th century.

As installers of both PVCu and Aluminium to the New Build market, the importance of on time delivery is totally time critical.
Over the last 20 years Quantum windows have worked closely with PGB to partner with us and deliver our offer to site.
Highly professional, and a pleasure to have worked with them so closely over the years.
