Welglaze’s PVC-U vertically sliding sash windows combine traditional looks with modern technology. They are designed to keep you and your family warm and comfortable whilst also reducing unwelcome, external noise.

Our PVC-U bay windows are fully reinforced with galvanised steel or aluminium profiles.

Optional bay pole jacking system is available for load-bearing situations.

All woodgrain foiled cills allow for any potential heat build-up due to the darker colour of profile.

Energy-rated windows can be used in the bay configuration helping to reduce the cost of heating your home.
