    Frequently Asked Questions

    What is sash in sliding window?

    Vertical sliding sashes are windows that open by moving vertically. These windows comprise two window sashes within frames. One sash is placed in front of the other, both seated in frames equipped with vertical grooves. These grooves enable seamless upward and downward movement, eliminating the risk of friction and potential damage between the frames.

    What are the different types of sliding sash windows?

    There are 3 main styles of sash window to choose from; your choice will depend on which suits you home's aesthetics and, potentially, which period it dates from. Georgian: feature 'six over six' panes. Victorian: feature a 'two over two' grid design. Edwardian: include panes which are 'six over two' in design.
