Optio Window Range
At Dorwingear, we supply and fabricate the ALUK Optio range with a wide selection of window frame options. These suit different applications, including varying interface depths and bay angles.
Optio 58BW Flush HI Window System
The 58BW ST Flush window delivers a clean, modern look with slim sightlines and a true flush finish. It combines the sleek appearance of the ST system with the proven performance of the 58BW range, making it a strong choice for both new-build and refurbishment projects.
You can choose from three slim sash options and a variety of configurations to suit your design. This flexibility allows the window to fit both contemporary and more traditional settings.
A double rebate design improves weather resistance, even in more exposed locations. The system also uses shared hardware with the 58BW and Heritage ST ranges, ensuring consistent performance and durability across different applications.
We fabricate this window using compatible profiles from the wider 58BW system. As a result, installation becomes quicker and more efficient, without compromising on quality or finish.

58BW ST HI Window System
The 58BW ST HI Steel Replacement Window offers a practical solution for projects that require a traditional steel appearance. It delivers the classic look of steel windows while benefiting from the performance and durability of aluminium.
This system suits heritage properties, listed buildings, warehouses, and similar environments where maintaining the original character is essential. It works particularly well when replacing existing steel windows or matching established architectural styles.
The design replicates the slim sightlines typically associated with steel frames, creating an authentic finish without compromising on modern standards. You can choose from a range of configurations, including top hung, side hung, fixed light, and French casement options.
In addition, the system includes carefully selected hardware that reflects traditional steel window detailing. This ensures a consistent appearance while improving security, performance, and long-term reliability.
Optio 58BW Flush HI Window System
The 58BW ST Flush window delivers a streamlined appearance with clean lines and reduced sightlines. It combines a modern flush finish with the proven strengths of the wider 58BW system, offering a balance of performance, flexibility, and security.
You can choose from three slim sash options along with a variety of configurations. This allows Dorwingear to tailor each window to suit both new-build developments and refurbishment projects, especially where a contemporary look is required.
The double rebate design improves protection against the elements, helping the window perform well even in more exposed locations. Shared hardware with the 58BW and Heritage ST ranges also ensures consistent operation and durability across different applications.
Because the system uses the same sashes, components, and hardware as the 70mm 58BW suite, we can fabricate and install it efficiently. This simplifies the process while maintaining a high standard of finish and performance.
58BW Open-Out HI Window System
The 58BW open-out window system offers a practical, high-performing solution with slim, modern profiles. Its outward-opening design helps maximise internal space while maintaining a clean external finish, making it suitable for both residential and commercial projects.
You can configure the system in a range of styles, including top hung, side hung, and French casement options. This flexibility allows you to adapt each window to suit different building layouts and requirements.
The system combines simple, clean lines with reliable functionality, meeting the demands of modern construction. It also provides a cost-effective option without compromising on quality or performance.
With Secured by Design accreditation, PAS 24 testing, and a Green Guide ‘A’ rating, the 58BW system delivers strong security, sustainability, and long-term value for your building.

58BW TBT Open-In HI Window System
The 58BW tilt and turn window system offers a versatile open-in solution that adapts to everyday use. You can tilt the window inward to allow fresh air into the space while maintaining security.

You can also personalise the finish with a wide range of colours and textured options from the ALUK collection, helping the window match the look of your property.
The system also performs reliably in all weather conditions. It resists wind, rain, and air infiltration, helping maintain a comfortable internal environment. With PAS 24 and Secured by Design accreditation, it provides strong levels of security alongside a modern, stylish finish.
