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.
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.
Every Designer Door Company window comes with a WER ‘A’ Rating as standard. Designed for enhanced energy and thermal performance, Designer Door Company’s multi-chamber design minimises heat loss through the frame, whilst the Soft Coat glass, warm edge spacer bars and high-performance glazing reflects internal heat back into the home whilst absorbing solar energy from outside.
