Sustainable Aluminium Windows

We all want to be as environmentally friendly as possible, so D&I is proud to be a provider of windows that are highly sustainable. Aluminium is a great material for recycling and the double glazing we use in our aluminium windows is made from sustainable materials. At the end of your product’s lifetime, it will not end up in as landfill but recycled for future use. However the lifetime of your aluminium windows is long, thanks to their natural durable and robust nature.

Improved Energy Efficiency

One of the main reasons we decided to partner with Sheerline is because their aluminium window includes a Thermavic® multi chamber thermal design that helps to thermally insulate your home. The double glazing that is used in this window is also of the highest quality, which gives your York home unbelievable thermal efficiency. Once installed these windows can achieve U-values as low as 1.4W/m2K. To learn more about how our aluminium windows can help your York home’s thermal efficiency, please call us.

Increased Security

The security of your York home we know is really important to you, that is why our aluminium window design incorporates a unique style of corner jointing that secures the glass to the unit without protrusions, preventing it from being pulled open. Combined with our cutting edge secure locking systems, your home will be safe from unwanted visitors, in fact our aluminium windows are so safe and secure they are PAS 24 enhanced security accredited and are Secured by Design certified. Install our aluminium windows in your York home to keep your family safe and secure.

Contemporary Design

One of the main design benefits of aluminium is that it’s natural strength allows it to support large amounts of glazing with very thin frames, so you are rewarded with windows that let in a large amount of natural light. Slim sightlines starting at 59mm, will give your York instant added kerbside appeal and their sleek design will complement any period of York architecture. If you are worried about customising your own aluminium windows, don’t worry our friendly team is on hand to guide you through the entire process.
