Choose Your Aluminum Sliding Patio Door Configuration

Every home is different and that’s why the Cortizo 4700 is made to measure, tailored to your exact specification. Choose from two or three-panel configurations or go larger with multi-track options to create impressive, fully opening walls of glass.

You can also customise the finish with a wide range of powder-coated colours, dual-colour options and even textured or anodised effects. Whether you want bold black, clean white, modern anthracite grey or a colour unique to your design scheme, you’ll find a finish to match your vision.

Homeowners today want bright, open spaces — and nothing achieves that better than large panes of glass. With the Cortizo 4700, you can enjoy breathtaking glazed surfaces that maximise light and transform your interior atmosphere.

By bringing the outside in, these sliding doors don’t just look great — they create a lifestyle. Think sunlit mornings in the kitchen, open-air entertaining with friends or simply enjoying an evening view from the comfort of your sofa.

Style means nothing without performance — and here’s where the Cortizo 4700 shines. Engineered to exceed modern energy efficiency standards, this system uses a thermally broken aluminium profile that reduces heat loss and improves insulation.

Depending on your glass choice, the doors can achieve U-values as low as 1.1 W/m²K, ensuring your home stays warm in winter and cool in summer. With rising energy prices and increased focus on sustainability, this kind of thermal performance is a smart investment in comfort and cost savings.

If you’re looking to add value, maximise light and create a seamless connection between your home and garden, the Cortizo 4700 Sliding Door is a truly stunning solution.
