Aluminium Sliding Doors

Slim, Strong, Stunning

Aluminium sliding doors are a sleek and modern solution that bring strength, style, and functionality to any property. Designed with slim frames and large glazed panels, they maximise natural light and provide uninterrupted views, creating a bright and spacious atmosphere.

One of the greatest advantages of aluminium patio sliders is their durability. Resistant to rust, warping, and weathering, they require minimal maintenance while retaining their performance and appearance for decades. Their slim sightlines make them ideal for contemporary homes, offering a clean, elegant look without compromising on strength.

Aluminium sliding doors are also highly energy-efficient, especially when fitted with advanced glazing, helping to maintain comfort throughout the seasons and reduce energy costs. Combined with robust security features and smooth operation, they are a practical yet stylish choice that enhances both modern living spaces and commercial projects.

✅ A wide range of styles, finishes, and configurations tailored to your needs

At UGS Ltd, you don’t just imagine your perfect space — you see it come to life before your eyes.

At UGS Ltd, all our doors can be supplied with either double or triple glazing, both designed to deliver outstanding thermal efficiency and year-round comfort. Whichever option you choose, you can expect excellent insulation and noise reduction, helping to create a quieter, more energy-efficient home.

For even greater performance, all glazing units are supplied argon-filled as standard. This inert gas reduces heat transfer through the glass, improving insulation, minimising condensation, and supporting long-term energy savings. The result is a warmer, more comfortable living environment with lower heating costs.

For enhanced security, glazing can also be specified with laminated or toughened glass, providing increased resistance to impact and greater peace of mind.

To add a personal touch, we also offer Pilkington decorative glazing, enabling you to choose from a variety of textures and patterns that enhance the character of your doors while maintaining light and privacy. For further options, explore our General Glazing, Specialised Glass, and Integral Blinds pages to discover the full range of premium glazing enhancements.

*Energy Rating show overall energy efficiency of the product. The entire window (the frame and the glass) is assessed to allow for heat loss, draughts and solar gain, giving a rating that indicates the overall impact of fitting that window in your home. 

*The R Value Measures resistance to heat gain or loss. Example, a typical insulated wall has an R-value anywhere from 12 to 19. 

*The U Value of the glass tells us heat loss through the glass, the glass edge and the frame. *The G Value of the glass tells us how well the glass transmits heat from the sun.

Modern aluminium sliding doors are designed with thermal breaks—insulating materials inserted between internal and external aluminium profiles—to reduce heat transfer and prevent cold bridging. When paired with high-performance double or triple glazing, good seals, and warm‑edge spacers, they can achieve U‑values that comply with current building regulations.

Yes — when specified correctly. Aluminium patio sliding doors can be fitted with multi‑point locking mechanisms, anti‑lift devices, and reinforced profiles to enhance security. Some systems also structurally bond the glass to the frame for increased strength.

The number of sliding panels depends on the width of your opening. You may see configurations from two panels up to six panels (or more with some systems). Many systems also include fixed panels behind which sliding panels stack. Some advanced designs allow all panels to slide (or pocket away) to create a fully open span.

Aluminium sliding doors are relatively low maintenance. Occasional cleaning with a mild soap solution is usually enough to keep them looking good. You should also regularly inspect and clean tracks to remove debris, and check seals and weatherstripping to ensure they remain intact and functional. Periodic lubrication of rollers (if the system allows) can help maintain smooth operation.
