Roof Lights Bringing Natural Light Into Commercial Buildings.

AGS designs and installs glazed rooflights for commercial buildings, from individual rooflights and large-format overhead glazing to bespoke structural glass installations. Whether the requirement is a straightforward glazed opening or something considerably more ambitious, we’ll develop the glass, supporting structure and installation around the building.

Framed Or Structural Glass

Depending on the design, commercial rooflights can be constructed using aluminium framing or structural glass with minimal visible support. We can provide:

  • Aluminium framed rooflights.
  • Structural glass rooflights.
  • Large-format roof glazing.
  • Multi-panel rooflights.
  • Walk-on glass where required.
  • Glass beams and structural glass supports.
  • Bespoke shapes and configurations.
  • Solar-control and specialist glazing.

Where required, glazing calculations are undertaken to determine the appropriate glass specification for the size, loads, support conditions and location.

Getting The Glass Specification Right

Overhead glazing has different demands to vertical glazing. Glass composition, thermal performance, solar gain, drainage, deflection and the supporting structure all need to be considered as part of the complete installation. We work with architects, designers and project teams to develop a rooflight that achieves the intended appearance while making sure it can be manufactured, supported and installed properly.

Designed Around The Installation

With large commercial rooflights, getting the glass onto the building can be as important as designing the rooflight itself. Access, lifting positions, crane requirements, glass size and installation sequence all need to be understood before manufacture begins. We consider how the rooflight will be installed while we’re developing how it will be built.

Discuss Your Commercial Rooflight Project

If you’re designing a commercial building that needs more natural light, send us the drawings. From a single rooflight to a complex structural glass installation, we’ll 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
