How to install commercial glass: A professional guide to large-scale glazing projects

Commercial glass installation is a highly specialised field, demanding precision, technical know-how, and strict adherence to safety protocols. At SGC Glass, we have been at the forefront of the glazing industry since 1995, delivering reliable solutions for commercial buildings across London, Essex, and the surrounding areas.

This comprehensive guide breaks down the professional process of how to install commercial glass, from the first step of site preparation to the final inspection, ensuring trade professionals have a clear understanding of industry best practices and SGC Glass’s commitment to excellence.

The installation of commercial glass – whether for shopfronts, commercial doors, or large-scale window replacements – requires more than just technical skill. It demands a systematic approach, tailored solutions, and a deep understanding of both the structural and aesthetic needs of each commercial building.

SGC Glass combines decades of experience with advanced techniques and state-of-the-art technology to deliver installations that stand the test of time, ensuring safety, durability, and visual appeal.

The commercial glass installation process

1. Initial assessment and consultation

Every successful installation process begins with a thorough assessment of the site. Our expert team conducts detailed surveys to determine the dimensions of the rough opening, assess structural integrity, and identify any unique project requirements. This initial consultation allows us to recommend the most suitable glazing options, whether it’s for new windows, glass doors, or bespoke shopfronts.

2. Custom design and fabrication

Once the assessment is complete, the next step is to develop a custom design tailored to the client’s needs. Working closely with architects, developers, and business owners, we specify the type of glass, framing system, and hardware required. Precise fabrication follows, ensuring each glass panel and window frame matches the project’s specifications for a seamless fit and optimal performance.

3. Site preparation: Laying the groundwork

Proper site preparation is crucial to the success of any commercial glazing project. This involves:

• Removing existing glass or structures carefully to avoid damage.
• Cleaning and clearing the workspace.
• Inspecting the rough opening for any structural issues or damage.
• Ensuring all support structures and window frames are level, secure, and free from imperfections.

Addressing these factors at the outset prevents complications during installation and contributes to the longevity of the finished product.

4. Frame and support structure installation

The installation process continues with the precise fitting of window frames or support structures. Accurate alignment and secure anchoring are essential to support the weight and function of the commercial glass. SGC Glass uses only the highest quality materials to guarantee stability and long-term reliability, whether installing standard frames or custom aluminium fabrications.

5. Handling and installing the glass

Handling commercial glass panels requires skill and specialised equipment, especially for large-scale or high-level installations. Our trained glaziers use tools such as spider cranes and suction lifters to position glass safely and accurately, reducing the risk of breakage and ensuring a flawless fit. Each panel is carefully set into the frame, with attention paid to even spacing and correct orientation.

6. Sealing and weatherproofing

After the glass is in place, we apply high-performance seals and gaskets to prevent air and water ingress. Proper sealing is vital for maintaining the energy efficiency, insulation, and weather resistance of the installation. All fasteners and fixings are checked for security, and any necessary trim or finishing hardware is installed to complete the look and function of the system.

7. Quality assurance and final inspection

At SGC Glass, quality and safety are our top priorities. Our team conducts a rigorous final inspection, checking for:

• Proper alignment and secure fitting.
• Effective sealing and weatherproofing.
• Compliance with relevant safety standards and building regulations.
• Overall appearance and finish.

We also provide clients with maintenance recommendations to ensure ongoing performance and longevity of their commercial glazing.

What makes commercial glass installation different from residential projects?

Commercial glass installation involves larger panels, more complex support structures, and stricter safety regulations. It requires advanced equipment, precise coordination, and specialist expertise to manage the unique demands of commercial buildings.

Safety protocols and best practices

Safety is non-negotiable in commercial glazing. Our glaziers are fully trained in the latest safety standards, including the use of personal protective equipment (PPE), safe handling of heavy glass, and working at height. We routinely assess risks and implement measures to protect both our team and the public throughout the installation process.

Key safety practices include:

• Comprehensive risk assessments before work begins.
• Use of certified lifting and access equipment.
• Strict adherence to health and safety regulations.
• Ongoing training for all installation personnel.
