High-level and oversized glass installations require a combination of precision, safety, and expertise. These projects are among the most complex in the glazing industry, demanding advanced equipment and highly skilled professionals.
Whether it’s a glass façade, structural glazing system, frameless glass balustrade, or shopfront installation, ensuring the right installation techniques and safety measures is crucial.
At SGC Glass, we specialise in delivering high-level and oversized glass installations across London, Essex, and the UK. Our team of expert installers has years of experience handling projects in large buildings, ensuring minimal disruption and maximum safety.
This guide explores the challenges, solutions, and best practices in this demanding field.
What are high-level and oversized glass installations?
High-level and oversized glass installations refer to complex glazing projects involving large glass panels or installations at significant heights. These include:
- Structural glazing for façades and curtain walling
- Glass balustrades for balconies and terraces
- Frameless glass windows and doors
- Glass roofs, rooflights, and canopies
- Shopfronts
- Double glazed units
These installations require specialist equipment, such as cranes, cherry pickers, abseil teams, and glazing robots, to ensure safe and precise placement.
Key challenges in high-level and oversized glass installations
1. Accessing high-level areas
Installing glass at height demands specialist access solutions. Cherry pickers, cranes, and scaffolding are often required to reach the side of a building, particularly in city environments like London. In some instances, using abseil teams can minimise the use of machinery and help avoid disruption to local businesses, making it an ideal solution for urban projects where space is limited.
2. Safety considerations
Ensuring a strong safety barrier for both workers and the public is crucial. Balustrade glass, for instance, must meet stringent safety regulations to function as an effective safety barrier. At SGC Glass, we adhere to strict safety protocols, which include:
- Pre-start meetings to discuss project specifics and safety measures.
- Pedestrian management plans to ensure the safety of the public near the work site.
- Pavement permits for partial or full road closures, allowing for a safer installation process.
- Access permits, particularly for roof works.
- Parking bay suspensions to create space for machinery and ensure smooth project flow.
The best way to install high-level and oversized glass
The best way to install high-level and oversized glass is through a combination of advanced planning, the right equipment, and skilled installers. SGC Glass follows a systematic approach:
- Conducting a detailed site survey to assess challenges.
- Selecting appropriate glazing systems, such as structural glazing, façade systems, and curtain wall systems.
- Using cranes, cherry pickers, or certified abseilers (IRATA certified) for safe handling.
- Ensuring compliance with UK safety regulations.
- Scheduling work during off-hours to ensure minimal disruption.
Essential equipment for complex glass installations
- Cranes and glazing robots
Lifting heavy panes of glass requires specialist equipment like cranes and glazing robots. These ensure precise positioning without the risk of damage. - Cherry pickers and scissor lifts
For high-level access, cherry pickers provide flexibility and safety. These allow installers to reach difficult angles, ensuring secure installation. - Forklifts for heavy loads
Transporting glass panels on-site requires forklifts, particularly for large building projects where multiple glass units need positioning.
What thickness of glass is best for high-level installations?
The required thickness of the glass depends on the application. Generally:
- Balustrades and façades require laminated or toughened glass for added strength.
- Roof glazing and canopies need support beams.
- Frameless glass doors and windows use double or triple glazing for energy efficiency and soundproofing.
Why choose frameless glass for high-level installations?
Whether used in glass extensions, balconies, or structural glazing systems, frameless glass provides an unobstructed view while maintaining strength and safety. With no bulky frames to obstruct sightlines, this design expands open space while ensuring compliance with structural glazing regulations. Balustrade glass and frameless windows also contribute to a sleek, contemporary look that integrates seamlessly with modern architectural design.
How do you ensure safety in high-level glass installations?
Safety is paramount in high-level glazing. SGC Glass follows strict protocols, including:
- Using certified installers with CSCS accreditation.
- Implementing strong safety barriers to protect workers and the public.
- Following UK building regulations for load-bearing glass.
- Carrying out risk assessments before installation.
Best practices for replacing high-level glass panels
When replacing high-level glass, proper planning is crucial. SGC Glass ensures a smooth process by:
- Conducting a thorough site assessment.
- Using specialist equipment to remove old glass safely.
- Installing new glass panes with minimal disruption.
- Ensuring compliance with safety regulations.
