    Replacement aluminium casement windows in Ipswich, Essex and Suffolk

    With possible U-Values of 0.9 which gives these windows an energy rating of A+, your home will feel warmer than ever and your heating bills reduced. This is achieved with innovative Aerogel technology which has the lowest thermal conductivity of any solid material. 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 benefit from modern manufacturing processes which eliminate any need for upkeep. So, you won’t need to worry about repainting or varnishing the frames. They 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 a powder coating that can be designed in over 150+ RAL colours and authentic woodgrain effects, they can easily accommodate any homeowner’s individual tastes. From contemporary Anthracite Grey, to elegant Chartwell Green, or traditional Oak frames, aluminium choices are incredibly versatile.

    Aluminium windows can be installed with either double glazing or comfort glass units. Both utilise innovative specifications to ensure that the warmth is kept inside and the cold out. This is achieved through a design that uses two panes of glass that surround an argon gas-filled chamber. Our advanced Comfort Glass options are designed to outperform triple glazing thanks to the inclusion of a tough laminated layer and an effective low-e coating. So, not only are they highly thermally insulating, but they’ll also reduce the external noises that enter your home.
