Designer Door Company aluminium windows are not only extremely elegant and slender, the A-rated, Low-E glass fitted as standard also makes these products one of the most energy-efficient window systems on the market. Like all the products from our windows range, our aluminium windows are manufactured to precise standards and come with the most sophisticated security features available to us.
Beautiful By Design.
Regardless of the project size, our high-quality aluminium windows will enhance the interior and exterior appearance of any home. A larger glazed area is achieved due to the slimmer frame, which allows for more natural light to pour into your property, and offers improved thermal efficiency properties, soundproofing and weatherproofing. And with global sustainability being one of our top priorities, all frames in our aluminium range are 100% recyclable, which helps reduce the carbon footprint.
