Versatile flush sash window designs

They say it’s often the little things that make the biggest difference. Each window is intricately made to meet your unique requirements, no matter how big or small your home improvement project is.

We offer flush sash windows with fully welded, full mechanical, or mechanical/weld joints to create a style that will perfectly complement your home’s existing character. With a variety of authentic timber-replica finishes and classic extras like Georgian bars, decorative glass, or beautiful leaded detail to choose from, literally any look can be achieved.

Can you put UPVC windows in a conservation area?

Those living in listed buildings and conservation areas must take extra care that window and door replacements do not differ from the original design. So, first things first, be sure to check with your Local Authority whether your home is in a conservation area or not.

Thanks to technological advancements, high quality timber alternative windows (like ours!) are designed to pass strict regulations in conservation areas. Robust, secure, and revitalising, you can count on our advanced flush sash windows to retain classic aesthetics whilst fully complying with the latest conservation rules in your area.

High performance flush sash windows

Performing to some of the highest energy efficiency levels around, our flush windows are A rated as standard and can accommodate 28 mm ECOMax double glazing or 32 mm Comfort Glass with ease.

Combined with modern multi-point shoot bolt security locks, stylish lockable handles and a convenient lockable night vent facility as standard, security issues associated with real timber - such as dry rot, pest infestation and warping - are a thing of the past with exquisite flush sash windows.

What is a window sash?

A window sash is a frame that holds the glass panes within a window. It is the movable part of the window that can be opened and closed, usually consisting of vertical or horizontal panels that slide or pivot.

What is the difference between a casement window and a sash window?

A casement window is hinged at the side and opens outward like a door, while a sash window has one or more movable panels that slide vertically or horizontally within the window frame. Casement windows provide unobstructed views and better ventilation, while sash windows offer a traditional aesthetic and are often found in older buildings.
