The best in steel-look windows

Architectural quality, with modern technology

Our signature ALUCO windows collection is inspired by traditional, industrial steel windows and the highly sought-after heritage, Art-Deco and Scandi-style. Combining cutting-edge technology with artisan designs and craftsmanship, we create striking but minimalist metal frames featuring slim sightlines and iconic grid-like designs. With styles ranging from classic heritage to contemporary, these versatile windows, with matching exterior doors, have the ability to completely transform a home, flats, apartments or commercial buildings, letting in more light and creating luxury spaces.

Custom-designed with elegance

The desirable steel look created for any home

Aluco windows are completely bespoke and made to your precise sizes, design, colour and handle options. We create fully opening windows in a side-hung or top-hung design with optional fixed panels. All feature symmetrical and balanced styling, typical of classic metal windows, with the slimmest possible frames, in five design options, allowing the maximum amount of glass. Colour-matched mullions, transoms or glazing bars create the grid-like pattern, or you can opt for fully glazed windows with sleek lines, suitable for new or existing openings, timber frames, or stone surrounds.

Aluco Windows – timeless style with 21st-Century technology.

Perfect as a replacement for old metal windows, in new build openings or when you desire to enhance your home with this distinctive and sought-after style, Aluco windows deliver a classic industrial finish, desirable slim sightlines, and provide maximum natural light whilst delivering optimum security and weather performance, and excellent energy efficiency. Frame depths of 70mm suit replacement applications, whilst narrower frames suit stone mullions or timber subframes.

Aluco steel-look windows also have unique features that are unavailable in comparable steel-look windows. Thinner glazing bars, the widest choice of handle styles and colours, and even structural bay poles when replacing existing bay windows. Every window we craft for you is unique and designed just for you.

Latest generation thermally insulated frames, protected by a beautiful and durable colour finish, work with high-specification glass to deliver windows with excellent insulation, helping save money on your energy bills. Of course, security is first-class with multipoint locking systems operated by a choice of stylish yet robust window handles. Extensive sealing and great design ensure Aluco windows provide optimal weather protection. Choose from an array of colour options from a single colour or dual colour if you prefer a contrasting look from inside to the outside of your home. All Aluco windows can be dressed with a number of handle options ranging from classic art deco, contemporary teardrop or the original steel look.

Despite their classic styling, Aluco windows deliver functionality, practicality and safety. First-floor windows are available with fire-escape hinges, also providing an easy-clean facility, letting you clean the outside pane of glass from inside the room. Or we can provide safety with optional window restrictors, preventing children from opening the windows too wide. Every detail of these windows is carefully thought out to give you stylish windows that are designed for everyday and family living.

Aluco offers several options for styling. The Traditional design is perfect for cottages and character properties, with its horizontal glazing bars and classically styled frames. The flush design option provides a uniform appearance with horizontal and vertical bars to match the sizes of the frame profiles. Steel-look has the most authentic styling with the right size glazing bars and suitable period handles. Also available is our Slim Design, using the thinnest possible frame profiles, and the Equal Sightlines version creates a fully symmetrical window with dummy sashes in the fixed panels. Nothing looks or feels like Aluco Windows – giving you the best possible styling, performance and always beautiful aluminium windows.

Just completed house renovation, using all the internal bespoke doors with glass panels. Absolutely delighted with the quality of doors and service. I was assisted every step of the way in getting the right size and format of extremely tall door. Keiran has been exceptionally helpful to deal with over the months from ordering to completion. 10/10I never usually do reviews but but I would say the whole experience and end result that has been achieved has been amazing.

So pleased with our new Aluco bifold doors, the best we could find on the market! We wanted bifolds with maximum glass area and no bulky frame and the Aluco doors were the perfect choice. Stunning, deep matte black colour, high quality, great choice of hardware and a first-class service. Highly recommend!

I recently had 3 sets of ALUCO exterior crital styled steel framed doors fitted to my property as part of an ongoing renovation. After looking around at various options Aluco was the only manufacturer that I felt could deliver the style I was looking for. With most other companies I thought the design was bulky and not finished to the finesse Aluco has achieved . Based on my experience I can honestly thoroughly recommend this manufacturer and will look to use them again on any future projects
