SGC Glass awarded Harlesden Job Centre window replacement contract

SGC Glass was commissioned to deliver a complete package of uPVC windows and aluminium shopfronts at Harlesden Job Centre, a multi-elevation public building in North West London. The project replaced the original single-glazed Crittall windows with energy-efficient glazing solutions, improving thermal performance and comfort for building users.

Sectors

• Commercial glazing
• Commercial window and door installation

Project scope

uPVC windows

• 176 units installed using the Rehau Calibre 70 system
• Finish: White internal and external
• 150mm cills
• Glazing build-up: 4mm clear toughened / 20mm black warm edge spacer (argon filled) / 4mm clear toughened Low-e (1.2 U-value)
• Restrictor hinges to all openers to meet building regulations
• Locking espagnolette mechanism
• White uPVC infill panels to match existing
• 2 fire-rated windows (30 minutes)

Aluminium shopfronts

• 10 units installed using the AluK GT55 system
• Finish: White internal and external
• 180mm cills
• Glazing build-up: 6mm clear toughened Low-e / 16mm black warm edge spacer (argon filled) / 6.8mm laminated safety glass

The installation was delivered across multiple floors using fully boarded scaffolding and a material hoist. External works were completed with operatives in full fall-arrest systems, while internal access was managed using enclosed podiums.

Collaboration with the client

SGC Glass worked closely with main contractor ISG and the client team from pre-start meetings and detailed site surveys through to progress reviews. Regular communication took place via Teams calls and on-site inspections.

ISG selected SGC Glass based on previous successful projects, strong product knowledge, and the ability to offer cost-effective alternatives aligned with the client’s objectives.

Challenges and solutions

• Live site operations: Internal hoarding was installed to create exclusion zones and minimise disruption.
• Noise and dust control: Measures were introduced to protect staff and visitors.
• Shopfront installation: Completed during weekend working hours using a Jekko glazing robot to maintain safe public access at the main entrance.

Quality assurance

Workmanship was monitored through senior team inspections and AuditPro audits. The client consistently reported positive feedback on product quality and service delivery.

The project was handed over two weeks ahead of programme. Thermal performance improved by 50–64% compared with the original glazing.

Ongoing support

SGC Glass provided daily progress updates and quick responses to queries throughout. At completion, the client received a full O&M package including cleaning and maintenance manuals.

“The project was completed ahead of schedule, with strong communication and great attention to detail from the SGC Glass team throughout.”

Outcome

The Harlesden Job Centre project demonstrates SGC Glass’s capability to deliver large-scale commercial glazing solutions on time and to a high standard. The team continues to provide reliable, cost-effective installations across public sector and commercial projects throughout London and the South East.
