    Aluminium windows with tilt and turn functionality

    Exceptionally Insulated

    Aluminium is a thermally insulating material, and those thermal abilities can save you money on your energy bills

    Superior Strength

    Aluminium’s innate strength and sturdiness means it can hold larger panes of glass

    Super Slim

    Aluminium frames provide super slim sightlines, so you have an unobstructed view of the outside

    Long Lasting

    Aluminium is robust and can last for more than 45 years

    What are aluminium windows?

    Aluminium frames undergo rigorous extrusion mechanisms, with the profiles being welded together to a specific shape. During this process, they are fabricated to minimise the heat transfer of cold elements with thermal break technology. That's why aluminium windows offer unparalleled security and durability. The innate strength allows for large panes of glass to be held and with the edge of the aluminium frame being as close as 50mm to the glass, you can take advantage of more views.

    Why choose aluminium windows?

    Sleek & slender sightlines

    With slim frames it allows for wider expanses of glass and unobstructed views of the outside

    Lightweight, thermally sound design

    Featuring a unique polyamide thermal break, our thermally broken aluminium frames achieve A+ energy ratings and low U-values with ease.

    Effective protection against corrosion

    Finished in an anti-fade, anti-rust and anti-corrosion coating, our aluminium windows are exceptionally strong and weather-resistant.

    Long lasting security

    Able to last up to 45 years, the majority of our aluminium windows are tested to PAS 24 as standard.

    100% recyclable

    Durable, strong and endlessly recycled, aluminium is one of the most sustainable construction materials available.

    Peace of mind

    Backed by a 10-year guarantee and a commitment to exceptional craftsmanship and customer satisfaction.

    Insulate your home in Tonbridge, Rochester and Canterbury

    Aluminium windows provide excellent levels of energy efficiency. With U-values as low as 0.9 W/m²K and an energy rating of A+, you’ll soon see an improvement in your home’s performance and a significant reduction in your heating bills. Aluminium achieves such outstanding thermal performances through a number of sophisticated features. This includes thermally broken frames which keeps the heat inside and stops any draughts from entering by breaking up currents of airflow. Aerogel is included to further enhance the insulation abilities, as well as either our high-quality double glazing or comfort glass and warm edge spacer bars.

    If you’re looking for an environmentally friendly window material option, aluminium is a great choice. It is 100% recyclable material and loses almost none of its quality when recycled. It can be melted down and re-formed numerous times for an extensive lifespan. When you want to reduce your carbon footprint and help to protect the environment, aluminium windows are perfect.

    Slimline aluminium windows in a range of styles and designs

    Aluminium windows offer an excellent range of choices. Our range includes casement, tilt and turn and bay windows, as well as bespoke windows. These are custom designed to individual requirements, so you can choose any shape, size and style. We’ve previously installed aluminium windows in an array of shapes, including triangular, arched and round.

    Aluminium window frames have a smooth finish that no other material can achieve, so it’s assured to add a premium and modern touch to any home they’re installed on. Our premium aluminium windows can be designed in over 150+ RAL colours. So, whether you’re looking for sleek grey, elegant Chartwell green or classic white, we can install the ideal solution to add kerb appeal to your property. Depending on the style, they can be fitted with either our high-performance double or comfort glass. And with a range of window furniture elements to choose from, you can add the decorative finishes to perfectly add style to your home.

    Aluminium windows have a unique thin-framed design

    Aluminium windows are popular with homeowners who are looking for a slim window frame. They boast distinctively thin frames that will add an ultramodern and sleek aesthetic. Not only do they add style, but the thinner frames create panoramic views of the outdoors, so you can enjoy the views from the comfort of your home. They’ll allow an abundance of natural light to flood into your home, for a bright atmosphere inside.

    Although the design is formed of larger glazing panels and slimline frames, it still excels in its thermal insulation performances. With a draught-free design and high-tech frames, your home will be kept a comfortable temperature all year round.

    Aluminium is the strongest window material available

    Aluminium is a naturally strong material and is the most durable construction material you could choose for your new windows. So, you can be sure that your home is protected. Its inherent strength allows large areas of glazing to be supported with slimline frames.

    All of our aluminium windows have undergone rigorous testing and they meet all the current Building Regulations requirements for total peace of mind. We also test the security measures to common burglary methods, so they’ll keep unwanted intruders out of your home.

    We fit our range of aluminium windows with multi-point locking systems as standard to ensure that home security is maximised. Multi-point locks bolt the windowpane to the frame at several points, significantly increasing their resilience. So unlike older locking features which are only secured at one point, our aluminium windows will stay intact from extreme forces. If you’re looking for even further home protection, we can include additional security measures into your bespoke aluminium windows.

    Aluminium windows will perform for years to come

    If you’re looking for a replacement window option that will last for years to come, then our high-performance aluminium is for you. They boast a lifespan of at least 45 years, and with just basic maintenance they could continue to perform for even longer. We suggest just wiping the frames with a damp cloth every so often to remove any dirt.

    We finish the aluminium frames in a powder-coated protective layer which stops the colour from fading. It also protects the frames from rotting, corroding and splitting. Our premium aluminium has a triple weather seal, so whatever the conditions outside, they won’t weaken in their performance. So not only will they look like new, but you’ll still be benefiting from their excellent performances for many years.
