Aluminium Sliding and Bi-fold doors for every project

Aluminium is the perfect material for the construction of Sliding and Bi-fold doors. Aluminium’s lightness, its material strength and its insulative properties allow large sections of glass to be held and still make large doors easy to operate.

Each of Hydro’s in-house building system brands, SAPA, WICONA and TECHNAL produce a range of sliding aluminium products for the building industry – for both commercial and domestic applications. We’re able to offer architects, specifiers, metal builders, fabricators and homeowners a range of innovative, reliable and aesthetically pleasing aluminium sliding systems. Find out more about Hydro Building Systems here.

In addition to the Hydro building system brands, our extrusion plants and rolling mills are able to produce aluminium extrusions and rolled products for your own building systems, building applications, cladding and roofing. Hydro extrudes and rolls building industry products for a large percentage of Europe’s aluminium building product brands in a range of different sizes and applications.

Why choose aluminium for sliding or bi-folding doors?

Sliding or Bi-folding doors made from aluminium are strong, durable and highly corrosion-resistant. Compared to alternative frame materials such as wood, aluminium products don’t need regular painting or staining to keep them weather-proof. Hydro aluminium sliding doors and bi-folds can be specified in a range of finishes and treatments to make them extremely thermally efficient, desirable and virtually maintenance free in almost any environment.

Aluminium sliding doors and bi-folds are among the best-insulated on the market – the thermal technology in Hydro Building System products is such that aluminium frames are able to outperform plastic competitors (uPVC) for insulative properties.

uPVC and wooden windows and doors are liable to expand and contract with temperature changes. In comparison, aluminium as a building material is highly stable – there’s no movement in the products that would make windows or doors difficult to operate due to swelling.

Low carbon, 'Greener' aluminium for buildings

Hydro CIRCAL and Hydro REDUXA hangtags hanging on aluminium scrap


Hydro CIRCAL is our range of products made with recycled, post-consumer scrap. Using recycled aluminium, Hydro is able to drastically reduce energy use in the production phase while still being able to offer high-quality aluminium products.

Operating the most advanced aluminium sorting technology in the industry allows Hydro CIRCAL to provide some of the highest recycled content aluminium in the market. Currently we offer Hydro CIRCAL 75R that contains a minimum of 75% post-consumer scrap. The higher the recycled content, the lower the carbon footprint.

Hydro REDUXA is our series of low-carbon aluminium. By using renewable energy sources like hydro power, Hydro REDUXA reduces the carbon footprint to 4kg CO2e per kg of aluminium (less than a fourth of the global average). The result is aluminium with one of the world’s lowest carbon footprints – maximizing sustainable opportunities for our customers in the construction industry.

Using renewable energy from water, wind and solar, Hydro can produce cleaner aluminium than ever before.
