Windows & Doors For Buildings Where The Details Matter.

Commercial windows and doors are widely available. We manufacture and install them for projects where appearance, performance and the quality of the finished building matter. We don’t start with the cheapest system. We start with what the building needs.

The Right Solution For The Building

Depending on the design and performance requirements, we can provide:

  • Fixed and opening aluminium windows.
  • Side-hung, top-hung and tilt-and-turn windows.
  • Large-format windows and fixed glazing.
  • Curved aluminium windows.
  • Arched and shaped aluminium windows.
  • Aluminium entrance doors.
  • Steel entrance doors.
  • Single and double-door configurations.
  • Thermally broken and non-thermally broken options.
  • Double and triple glazing.
  • Solar-control, acoustic and high-security glazing.
  • Automated opening where required.
  • A wide choice of colours and finishes.
  • Bespoke configurations.

Because we work with different aluminium and steel systems, we can select the solution around the architecture, performance requirements and budget rather than trying to make one system fit every project.

Commercial Entrance Doors

Our aluminium and steel entrance doors can be developed around the size, appearance, usage and performance requirements of the building. From straightforward single and double doors to larger glazed entrances, we can incorporate the appropriate glass, hardware, locking and access requirements while keeping the framing and sightlines appropriate to the design. Where doors form part of a larger glazed elevation, we’ll develop the entrance and surrounding glazing as one coordinated package.

From Specification To Installation

Glass specification, opening sizes, wind loading, interfaces, drainage, hardware and the surrounding construction all influence the finished installation. We’ll work with the project team to resolve those details, undertake calculations where required and make sure what’s specified can be manufactured and installed properly.

Discuss Your Commercial Windows & Doors

If you’re specifying windows or doors for a commercial building where quality and performance matter, send us the drawings and specification. We’ll tell you what we’d recommend and 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.

What Our Customers Say

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
