Casement windows

Our casement windows can be designed in an almost infinite range and combination of opening configurations, fixed frames and vents. From standard designs to more detailed requirements, every window is custom made to suit your home.

Top hung

Available either as a single, top hung sash within an opening or combined with a fixed frame or dummy sash for larger openings, our top hung windows feature concealed hinges within the side of the frame. When the window is opened, the top of the sash is pulled downwards away from the frame and the base of the sash pushes outwards.

Side hung

Designed with concealed hinges in the top and bottom of the frame, our side hung windows are a classic design and one of our most popular window styles.

The window pivots outwards from the side when opened and can be utilised as a single opening window or as part of a larger configuration.

Tilt and turn

A contemporary addition to our window range, inward opening tilt and turn windows offer the flexibility of being able to tilt the window open for part ventilation or completely open the window up to make the most of nice weather or to clean – making them perfect for non-ground floor use and locations with difficult access.

Fixed frame window

Fixed frames

Whether you are creating a single fixed frame as a picture window or incorporating a fixed frame within a casement window alongside top-hung, side-hung or tilt & turn sashes, they provide complete flexibility and are ideal for filling rooms full of light. Depending on the configuration you can even opt for dummy sashes to match openings.

Thermally efficient aluminium windows

The incredibly versatile Thermo65 is ideal for projects that require enhanced thermal performance, including larger openings.

Thermal performance

Thermal performance of the doors is measured as a U-value. When comparing products it is crucial to compare the overall U-value of the system and not just the U-value of the sealed glass unit.

Window energy rating

Window energy ratings (WER) provide an indication of the efficiency of a window and are calculated on factors including the system's overall thermal efficiency, air leakage and solar gain. The WER for a window is dependent on the configuration, number of openings and the glass specification and as such is unique to each individual window.
