Please hover over each image to learn about details.

Frameless Sashes on Fixed Panels

On many sliding patio doors, even the fixed (non-sliding) panels are built inside a full sash frame, which leaves a chunk of visible aluminium around the glass. With the frameless sash design used in the Stellar Aluminium system, the fixed panels have no visible internal frame on the inside face.

Ultra-Slim Interlock

The slim 35 mm centre frame where the panels meet lets in more natural light and gives you a wider, uninterrupted view. Its minimalist design creates a sleek, modern look while maintaining strength and security. Perfect for maximising your glass area and brightening your living space.

Powder-Coated Finishing

The stellar aluminium profiles are coated with a durable powder finish that resists fading, chipping, and scratching. This high-quality finish keeps your doors looking fresh and vibrant for years with minimal upkeep. Available in a wide range of colours to perfectly match your home’s style.

Polyamide Thermal Break

A clever insulating barrier built into the aluminium frame that stops heat from escaping and cold from getting in. It improves energy efficiency, helping keep your home warmer in winter and cooler in summer. This means lower energy bills and a more comfortable living environment all year round.

Smooth Sliding Track System

High-quality rollers and a precision-engineered track allow the panels to glide effortlessly with minimal effort. You get a quiet, smooth operation every time you open or close your doors. Built to handle daily use while maintaining long-lasting performance.

Inline Sliding

The door panels glide smoothly along a single track, allowing them to open and close effortlessly without tilting or folding. This design saves space, making it ideal for areas where swing doors aren’t practical. Perfect for creating a seamless connection between your indoor and outdoor spaces.

Easy Installation

Engineered with precision to make fitting quicker and easier, reducing installation time and disruption to your home. All components are designed to slot together seamlessly, ensuring a perfect finish every time. Makes the process smoother for installers and hassle-free for you.

Do you love these options?

200mm Cill as Standard

Comes with a sturdy 200mm deep cill that directs rainwater away from your home, protecting your floors and walls. It’s built for durability and weather resistance, ensuring long-lasting performance. Provides a neat, finished look to the base of your sliding patio doors.

Trickle Vent

A discreet built-in vent that lets fresh air flow into your home, even when the doors are closed. Helps reduce condensation and improves indoor air quality without compromising security. Keeps your home feeling fresh, comfortable, and well-ventilated all year round

Styles & Configurations

Ultra Slim Stellar Sliding Patio Doors

The 2 panel option remains a popular choice, pairing one fixed pane with a smooth-gliding sliding panel for a simple yet elegant finish. For those who want a wider view and more natural light, the 3 panel design offers a central sliding door framed by two fixed sections, creating a balanced, symmetrical look. If you’re working with a generous opening, our four-panel configuration delivers maximum impact, with two sliding doors that can meet in the centre or stack neatly to one side for a seamless indoor-outdoor transition.

Every configuration is engineered with a precision double-track system, allowing panels to glide effortlessly while keeping the frame slim and stylish. We’ve kept the design of sliding aluminium doors intentionally refined, so a triple-track system is not available on this model. To ensure optimal weather resistance and smooth operation, the sliding panels always run on the exterior track.

We offer aluminium patio doors in a variety of configurations, ensuring there’s a perfect fit for every home and lifestyle. Choose from practical 2 panel layouts, versatile 3 panel arrangements, or impressive four-panel designs for larger openings.
