Create a home that you can enjoy no matter the weather with our energy efficient windows and high performance glazing options.

Aluminium Windows

At D&I Windows, we offer a wide range of windows, including uPVC, timber and aluminium frames. When it comes to energy efficiency, aluminium windows are your best bet; aluminium is considered to be one of the best materials on the market; it is solid and durable yet lightweight and highly energy efficient.

Our windows come in a range of styles and configurations to suit the appearance and requirements of your home as well as your budget. Our aluminium windows are available in tilt and turn and casement window designs. Not only are our aluminium windows a stylish and modern addition to your home, but they are excellent and energy efficient; their slim, sleek frames work as natural insulators. Our aluminium windows come with polyamide thermal break technology, which creates a barrier which slows down heat transfer to prevent heat from escaping through the frames, keeping your home warm in the colder months and cool in the hotter months.   

Another benefit of aluminium is that it is corrosion resistant, so when you install our aluminium windows, you won’t have to worry about the costs of maintenance or fixing them as they are made from the highest quality materials that require minimal upkeep, meaning they stand the test of time, this is ideal for busy homeowners. 


Double Glazing Windows

Upgrade your underperforming single glazing windows with our energy efficient double glazing windows, which come with U-values as low as 1.4 W/M2K to keep your home protected and comfortable. Double glazing works by trapping air bubbles in between two thick glass panes which slows down heat transfer so that heat can’t escape your home creating a cosy and comfortable space you and your loved ones can truly enjoy. 

Located in the North of Britain, we understand that the winter months can be extremely cold, so avoid being caught out by underperforming and outdated windows that let the cold in. At D&I, we want to ensure that your home is warm and dry all year round; with our aluminium windows, you don’t worry about draughts, leaks or mould; our expert installers will fit your double glazing windows tightly so no air can escape.

Triple glazing works the same as double glazing but includes a third layer of glass for ultimate thermal efficiency and comes with U-values as low as 0.9 W/M2K, which is one of the lowest values on the market right now.
