AluK: Heritage window designs. Customised, not compromised.

However, windows from this era are often accompanied by outdated performance, failing to meet modern standards or expectations. So, while the narrow steel windows found in former industrial buildings are typically replaced like-for-like during residential conversions, efficiency ratings and occupant comfort often suffer as a result. But there is a better way.

The experts at AluK have created and developed the slimline 58BW ST aluminium window system. It takes the best aesthetic qualities of steel windows and adds the inherent performance characteristics of aluminium.

Providing the narrow sightlines and timeless appearance of traditional materials, the system also offers superior thermal, acoustic and security performance. Plus, it’s available in a choice of colour and anodised finishes, with two frame depths and a range of configurations.

So, with the 58BW ST window system from the Experts in Aluminium, you can tick all the boxes, without compromise.

Balancing aesthetics and flexibility.

Refurbishing historic urban properties isn’t without its challenges, and considerations must be made. Key amongst these is the need to retain period features in order to comply with sensitive planning conditions.

The 58BW ST system has been designed and engineered to replicate the look of traditional steel window frames, allowing the appearance of refurbished properties to remain compliant, while delivering the performance and configurability that AluK’s cutting-edge solutions are known for.

Available in a range of traditional colours and anodized finishes – with top, bottom, side-hung, French casement and fixed light configurations – the system can be adapted to any industrial, commercial or residential conversion project.

• Narrow sightlines
• Available in a range of single and dual RAL colours
• Accommodates 24-32mm glazing units
• 58mm or 70mm frame depths
• Top, bottom, side-hung, French casement and fixed light configurations
• Accommodates standard hardware including friction stays and shoot bolt locking and safety features

Advanced performance and security.

Heritage designs shouldn’t be compromised by heritage drawbacks. While the 58BW ST system replicates steel windows’ style, it takes full advantage of the inherent properties of aluminium.

Utilising the combined knowledge of our time-served experts, it offers outstanding security, thermal and acoustic performance. The system holds Secured by Design (SBD) accreditation and is the first aluminium window system awarded a WER A-rating, whilst also Q-Mark certified.

• SBD accredited
• WER A rated
• Q-Mark certified
• Tested to PAS 24
• BRE Green Guide A rated
• Unique polyamide thermal break design for improved thermal performance
• Integrated deep head profiles for ease of trickle ventilation

Easy to install, easy to care for.

Though aesthetics and initial performance are important, so too are speed of installation, ease of glazing and resilience to unique pollution and weather conditions found in built-up urban areas.

The aluminium construction of the 58BW ST system is lighter in weight and can be either powder coated or anodised to retain its looks for years to come. Plus, without the need for frequent refinishing or additional corrosion protection, it helps to minimise whole-life costs.

• Dedicated fixing straps for ease of installation
• Robust powder coated and anodised finishes
• Available with internal beading for ease of on-site glazing
