    NextLevelWindow sash windows are designed to preserve the traditional beauty of period properties. Made from one or more mobile panels known as ‘sashes’ that form a frame to hold panels of glass, sliding sash windows open and close on a vertical slider.

    Available in uPVC or wood, our uPVC sash windows are made to measure and come with either an A or A+ rated energy rating as standard. Customise the look of your new double-glazed sash windows with a choice of colours, finishes, handles and glazing options – including decorative Georgian or Victorian bars for that cottage feel.

    The Benefits of NextLevelWindow Sliding Sash Windows

    Quality Build and Design

    Available as single or double-hung, which refers to how many sashes on the window can be opened, NextLevelWindow sliding sash windows offer a stunning level of detail visible on the outside and an equally impressive build quality hidden inside with customisable options in both uPVC and timber sash windows. Perfectly counterbalanced through a system of hidden runners and springs, the internal open and close mechanism opens and closes with a smooth and easy action. Our range of beautiful sash window colours preserve the authentic look of a classic sliding sash window. Customise your home by choosing from uPVC sash windows or timber sash windows. Select from a single colour frame or our dual colour options to create a different look on the outside of your home.

    Reinforced Against Intruders

    NextLevelWindow sash windows are built to keep you and your home warm, safe and secure. Made with toughened glass accredited by the British Standards Institute (BSI) and high energy ratings as standard, our double-glazed sash windows are draught free when sealed tight in winter and let the breeze flow in on hot summer days. There’s a range of security features built-in to both our uPVC and timber double glazed sash windows, including a security bar and reinforced sashes to prevent intruders trying to lever open the window. Choose to add lift restrictors to lock the sliding sash window open ajar for ventilation, preventing it from being opened fully
