Our uPVC Sash Window range are from Synseal Evolve VS fully featured A-rated profiles. Every sash window comes with stainless steel tilt restrictors to provide secure ventilation and allow access for cleaning. Metal key-locking sash hooks lock the two sliding sashes together when fully closed and travel restrictors can be specified to provide secure ventilation on ground floor or basement windows. This ensures the maximum security specification available while maintaining the traditional looks of a wooden sliding sash window.

uPVC Sash Windows do comply with fire escape regulations, keeping an equal split on the windows keeps the maximum clear opening for fire egress. On smaller windows the sashes can be specified as removable to allow the sashes to detach in the event of a fire. Toughened safety glass must be used in the lower sliding sash where the glass height of the lower pane is below 800mm from finished floor level. These details are specified to comply with current building regulations, at ESG Windows we are Certass registered and will provide a Certass certificate to confirm that your new sash windows comply with the regulations.

uPVC Sash windows offer a simple design alternative to casement or tilt & turn windows, due to the simply sliding design there is only one configuration available. Sash windows over 1500mm wide we will split in two the overall opening and couple two sash windows using a 30mm aluminium jointer, this ensures that the sliding sashes are not too heavy to ensure ease of use.

To add a more traditional look we recommend run-through sash horns, the fluted horns on the upper sash make the window look like a traditional wooden window. Astragal glazing bars give the look of genuine wooden Georgian bars with an internal spacer bar to give the effect of individual glass panes.

Our uPVC Sash windows are available in all standard upvc woodgrain foiled colours such as white, mahogany, rosewood and light oak. We also offer bespoke woodgrain foiled finishes such as Irish oak, chartwell green, anthracite grey, black and white woodgrain.
