SAPA Dualframe 75Si Casement Aluminium Windows
To achieve the project's performance requirements, Ali Systems supplied and installed SAPA Dualframe 75Si Casement aluminium windows throughout the building.

The Dualframe 75Si system incorporates an advanced polyamide thermal break, providing exceptional thermal efficiency without the need for complex sealed unit specifications. The system delivers excellent energy performance while maintaining the slim, clean sightlines expected from modern aluminium windows.

Each window was manufactured with high-quality system features including:
- Advanced polyamide thermal barrier technology for enhanced thermal performance.
- Tailed gaskets and a centre seal to reduce thermal radiation without foam inserts.
- Friction stay hinges, including egress hinges where required.
- Silver locking handles with green egress buttons where specified.
- 155mm horned subcills.
- External beading designed to comply with BS7950 without additional components.

Senior Architectural Systems SPW501 Commercial Doors
To complement the window installation, Ali Systems also manufactured and installed Senior Architectural Systems SPW501 Commercial Doors.

This thermally broken aluminium door system provides a robust, high-performance entrance solution ideally suited to commercial environments. The entrance doors were manufactured with low mobility, non-rebated thresholds to improve accessibility, while anti-finger trap hinge stiles help provide a safer entrance for staff and visitors alike.

The completed installation has transformed the Pay By Mobile Slots head office, creating a contemporary façade that is both practical and visually striking.
The slim aluminium profiles maximise natural daylight within the building while presenting a clean, modern appearance from the outside. The coordinated window and door systems provide a cohesive architectural finish that enhances the overall character of the property and creates an impressive first impression for employees, clients and visitors.

Alongside their visual appeal, the new glazing systems offer excellent thermal efficiency, helping to improve occupant comfort and reduce energy consumption throughout the year. Their durable aluminium construction also provides a low-maintenance solution designed to deliver reliable performance for many years.

This project demonstrates Ali Systems' ability to manufacture and install bespoke aluminium glazing solutions that successfully balance appearance, performance and practicality.

By combining the SAPA Dualframe 75Si window system with Senior Architectural Systems SPW501 commercial doors, Ali Systems has delivered a high-quality entrance solution that provides the Pay By Mobile Slots head office with a stylish, secure and energy-efficient frontage, perfectly suited to the demands of a modern commercial workplace.
