More Info

Slimline aluminium windows will become a key focal point of any room. This allows homeowners to truly capitalise on the view outside year round. Our aluminium windows will allow fresh air to freely circulate around the building, ventilating all of the rooms. Our windows not only effectively prevent draughts, but they also seal hot or cool air inside of the property. This ensures that these aluminium windows will not let the inside heat out or let in cold draughts.

Features & Benefits


We offer a variety of finishes for our aluminium windows. You will be able to choose from a range of internal and external finishes to design your windows to match your project perfectly. All of our aluminium windows are treated in a 12 stage chromate conversion coating process, which increases the resistance of the aluminium. The colours used on our windows, known as Fiji colours, are extremely resistant to scratches or scuffs. This helps to keep your windows looking nicer for longer.

Low Maintenance

Our Visiline aluminium windows are easy to keep clean, with maintenance free, powder coated Aluminium. This means that, even in the most extreme weather, your windows will remain in optimal condition. Our aluminium windows require minimal upkeep, are extremely durable and have a long life span. This means that you can rest assured that your windows will stay looking as good as they do at installation. Our windows also have triple glazing and a triple gasket seal which offers protection from the outdoor elements.

Natural Light

With maximum panel widths of 1400/2400mm (opener/fixed) and heights of 1600/2400mm (opener/fixed), our aluminium windows invite an abundance of natural light into your building. Aluminium is well known for its durability and is capable of holding bigger panes of glass than any other material. Therefore, our slim aluminium windows can offer you panoramic views and extreme performance. Not only do our windows improve the appearance of any home, but they will also make your property feel warmer through solar gain.

Peace of Mind

Our aluminium windows are completely compliant with the PAS 24 2016 security test. Our Visiline aluminium window and door systems have been tested by an independent third party and have been judged to be extremely secure. This means that our aluminium windows meet enhanced security performance requirements. Specially designed concealed hardware prevents our windows from being levered at the hinges. Many of our products, including our windows, are fully Secured by Design accredited, which means that they have received police recognition for their security.

Heat Retention

Visiline aluminium windows have superb thermal insulation through the integration of a fibreglass-strengthened composite profile. The windows’ thermal insulation can decrease the demand on your heating and cooling systems. This energy efficiency means that you will be able to keep your ideal temperature year-round. The insulation of the aluminium windows also helps to reduce noise pollution. Our aluminium windows are able to effectively minimise the impact of outside noise on your daily life. This can help improve your overall quality of life.
