58BW-TBT

Why Choose Our AluK Windows 58BW ST HI?

The 58BW TBT HI window is a popular choice for medium to high-rise properties. Made from high-performance aluminium, this sustainable system is inherently strong yet lightweight. The tilt and turn function also allows for easy cleaning, ideal for rooms above the second floor and above where ease of cleaning is essential.

Exceptional Safety & Seamless Operation

Clean lines and advanced functionality make the 58BW tilt before turn (TBT) HI window a popular choice for new build and refurbishment projects where safety and ease of operation are essential.

Offering exceptional child safety and seamless operation, our Tilt-before-turn windows can provide safe opening and ventilation for bedrooms.

 

HIGH PERFORMANCE

The 58BW TBT HI is a tried and trusted window system that delivers exceptional performance, functionality and safety.

Low U-values of 1.4 for double glazing and 1.2 for triple glazing, window energy ratings (WER) as low as ‘B’, and a Green Guide ‘A’ Rating, make this energy efficient window the ideal partner for both new build and refurbishment projects where warmth and comfort are paramount.

With impressive air (Class 4 - 600Pa), water (Class 8A - 600Pa) and wind (Class E2400 - 2400Pa) resistance test figures, this system can withstand extreme weather conditions, keeping your home warm and dry.

Safe and highly secure, this window system is certified under the Secured by Design scheme and tested to PAS 24, which means it has been rigorously tested.

The 58BW TBT range is available in several configurations to suit your project: tilt-before-turn, side-hung, fixed light, and multi-light. It is also available in two frame depths to suit the thickness of your walls: 58mm and 70mm.

As with all AluK aluminium systems, the 58BW Casement is available in single or dual-colour powder coating, texture and anodised finishes
