Designer Door Company’s Sliding Patio Doors: Aesthetic, Efficient, and Secure

Our sliding patio doors are installed with Argon gas filled double-glazed units for optimal thermal performance, with triple glazing, acoustic glass and reinforced glazing options available.

High-security 6-point locking systems are built into every patio door we design, and the doors are internally glazed as an additional safety feature. Our sliding doors are designed with a dual-purpose anti-lift mechanism which prevents panes being levered from the frame.

Our sliding door configurations offer a remarkable degree of functionality with our easy-glide system, and they can be opened and closed with astonishing ease. For accessibility, they also come with a low threshold option.

With interlocking door leaves, our sliding patio doors provide a robust barrier against the harshest of Northern Ireland’s seasonal weathers.

Our sliding patio door systems are not only aesthetically pleasing but also create a seamless flow between your home and the outdoors with less frame and more glass.

Our uPVC patio door range is easy to maintain, will never rot, rust or flake, and come in a large range of RAL colours with a foiled woodgrain finish available.

Our aluminium patio doors come in two, three, or four-panel options, such as our Triple-track sliding doors, which add a contemporary feel to any home improvement project. The thermally broken aluminium frame has a slimmer profile, with a dual layer of powder coating for optimal protection.

We offer our aluminium sliding doors in standard black, white, and anthracite grey, with almost any RAL colour available on request. 

Alternatively, we provide aluminium bifold doors and french doors too!
