Large Format Glazing Big Glass. Difficult Access. We Deal With Both.

From oversized shopfronts and showroom glazing to huge fixed panes and double-glazed units, AGS delivers large-format glazing for commercial buildings where conventional glass sizes simply aren’t enough. If it can be manufactured and there’s a practical way of getting it into position, we’ll work out how to install it.

How Big Can We Go?

There isn’t one useful answer. Glass size depends on the specification, available manufacturing capability, transport, site access and how the finished pane can physically be installed. Rather than putting an arbitrary maximum size on what we can offer, show us what you’re trying to achieve. We’ll work out what’s possible.

More Than Just Clear Glass

  • Depending on the project, large-format glazing can include:
  • Oversized single glazing.
  • Large double-glazed units.
  • Laminated and toughened glass.
  • High-security glazing.
  • Low-iron glass.
  • Solar-control glass.
  • Anti-reflective glass.
  • Curved glazing.
  • Specialist glass specifications.

Glazing calculations can be undertaken where required to make sure the specification is appropriate for the size, location and loads involved.

The Size Of The Glass Is Rarely The Biggest Problem

Getting it where it needs to go usually is. Large panes need to be transported safely, unloaded, moved through or around the building, lifted into position and installed without damage. Restricted loading areas, finished buildings, internal routes, upper floors and limited lifting positions can make the installation considerably more challenging than the glass itself. We plan the route, lifting method, specialist equipment, manpower and installation sequence before the glass arrives.

If It's Difficult, Talk To Us Early

Some designs look straightforward on a drawing but become much more complicated when you consider manufacture, transport and installation. Getting us involved early means we can identify those problems while there is still time to solve them. If something can’t practically be achieved as drawn, we’ll explain why and work with the project team to get as close as possible to the original design intent.

Discuss Your Large Format Glazing Project

If your project involves an unusually large pane of glass, send us the drawings. We’ll look at the glass specification, manufacturing options, access and installation and tell you how we’d approach it.

Our Process

Good glazing starts with good decisions.Every glazing project is different, but the way we approach them is consistent. Our process is designed to make the important decisions early, when they are easier and less expensive to resolve.We specify aluminium systems that best suit the building, the budget and the long-term expectations for the project.See our full process

01

1. Initial Conversation

Tell us about your project. Whether you have drawings, planning approval or simply an idea, we’ll listen first and ask the questions that need answering before recommending anything. If you’re a new client, we recommend visiting our factory early on to meet the team and see how we work.

02

2. Quote & Cost Options

Using the information you’ve provided, together with any drawings, we’ll prepare a detailed quotation clearly setting out what’s included and any exclusions. Unless a particular system has already been specified, we’ll recommend the one we believe best suits the project’s design, performance requirements and budget.

03

3. Order & Site Survey

Once an order has been placed, we’ll arrange a site survey. Our surveyors establish datums, measure structural openings and confirm the agreed details. We’ll also work with your builder or contractor to resolve any outstanding issues before manufacture begins. Access, logistics and installation considerations are assessed at this stage, helping prevent expensive problems later.

04

4. Drawings

We’ll produce a full set of working drawings for approval. These incorporate the agreed survey details and, where required, reference site datums so structural elements provided by others are clearly identified and dimensioned.

05

5. Procurement & Manufacture

Once the drawings have been approved, we’ll procure the materials and begin manufacture. We’ll then confirm the expected installation date to suit your construction programme.

06

6. Professional Installation

Before installation begins, we prepare site-specific Method Statements, Risk Assessments and Lift Plans where required. Our experienced installation teams carry out the work safely and in accordance with the approved drawings. We don’t rush work simply to move on to the next job.

07

7. Completion & Aftercare

Once installation is complete, we’ll inspect the finished work, make sure you’re happy with the result and remain available if you need us afterwards. Where applicable, operation and maintenance manuals will also be provided.

Alistair Colins 5 ★

AGS handled everything from design to installation of our sliding doors. The team were friendly, tidy, and clearly knew their stuff. The finish is flawless and has totally transformed our kitchen extension

Chloe Brown 5 ★

Our architect recommended AGS and we’re so glad they did. The aluminium glazing is solid, smooth to operate, and beautifully finished. Professional, courteous installers and excellent aftercare – genuinely outstanding service

James Watson 5 ★

For our new-build project, we needed a reliable company to design, manufacture and install all the aluminium glazing. AGS took full ownership of the package, liaising with our architect and builder. Their technical knowledge, especially around thermal performance and detailing, was excellent. The finished product is stunning and functions perfectly

Paul Hopworth 5 ★

We’re absolutely delighted with the glazing supplied and fitted by AGS. From the first survey to final sign-off, communication was clear and responsive. They went the extra mile to resolve a last-minute design change without delaying the project. The doors operate beautifully, feel solid, and the overall finish is outstanding

Peter Guilbert 5 ★

We wanted something a bit special – big slim-framed sliders, a glazed roof and frameless balustrades. AGS talked us through Schuco and Cortizo options and gave sensible advice on budget. The end result is amazing; loads of light, everything feels really solid and the neighbours keep asking who did it
