Aluminium Casement Windows Supplied and Fitted

The most popular window style in the most modern material, aluminium creates smooth, slimline frames. Aluminium casement windows have a flush sash which fits perfectly against the frame, for a look that complements traditional and newer homes. With over 150+ RAL colours, a range of window furniture and glazing options, the possibilities have never been greater.

Aluminium casement windows will protect your home whatever the weather thanks to their weather-tight seals and draught-proofed frames. They’re able to achieve energy A+ ratings in frames that are inherently robust, so upgrading your windows to aluminium casements will ensure your home is kept safe and secure.

    Replacement aluminium casement windows in Ipswich, Essex and Suffolk

    With U-Values as low as 0.9 these windows have an energy A+ rating. The frames are also fitted with a special polyamide thermal barrier, which traps the heat within the home and stops the cold from entering the room.

    When it comes to safety these windows really excel. With finger-safe hinges and side hung hinges that comply with fire exit regulations, your family’s safety is always in mind. They’re fitted with multi-point locking systems, which secure the window frame to the pane at several points. This significantly enhances its durability and protection, preventing forced entry.

    Aluminium windows only need an occasional wipe down with a damp cloth to get rid of dirt. They’re able to last at least 45 years and will continue to perform and look like new over their lifespan.

    Slimline aluminium casement windows in a range of modern styles and designs

    With powder coating that can be specified in more than 150 RAL colours, we can readily accommodate any tastes. From contemporary Anthracite Grey, to elegant Chartwell Green, or traditional Cream frames, aluminium choices are among the widest.

    Aluminium windows can be installed with either double glazing or comfort glass units. Our Comfort Glass option outperforms triple glazing thanks to the inclusion of a tough laminated layer and an effective low-e coating. Not only are they thermally insulating, but they’ll also reduce the external noise.
