Commercial performance. Sensible specification.

Not every commercial building requires the most expensive aluminium system available. What it does require is a system that has been properly designed, tested and proven for the demands of commercial construction.

That’s where Senior Architectural Systems, known throughout the industry simply as Seniors, fits.

Designed for Commercial Buildings

Seniors offers a comprehensive range of commercial windows, doors, curtain walling, shopfronts and roof glazing systems designed to work together across the building. For AGS, it’s often the right choice when a project requires dependable commercial performance, strong technical capability and a competitive overall specification.

Commercial glazing has to do more than look good. Windows, doors and façades may need to withstand constant use, changing weather conditions, demanding security requirements and the practical pressures of busy buildings. The system must also satisfy the specification, integrate with the wider building and remain commercially viable.

Seniors has developed its product range around those demands. Its compatible window, door and curtain wall systems allow us to produce complete aluminium glazing packages for offices, retail developments, schools, healthcare buildings, apartments and other commercial projects without introducing unnecessary cost or complexity.

A Complete Commercial Aluminium Package

Because we manufacture across the complete Seniors range, we can select the right system for each part of the building rather than forcing one product to perform every role. Depending on the project, this can include:

  • Commercial aluminium windows.
  • High-traffic entrance doors.
  • Thermally broken doors.
  • Sliding and bi-folding doors.
  • Curtain walling.
  • Shopfront systems.
  • Roof glazing.
  • Fixed glazed screens.
  • Double and triple glazing.
  • Enhanced security specifications.
  • Automated opening and ventilation systems.
  • Bespoke colours and finishes.

The systems are designed to work together, allowing appearance, performance and detailing to remain consistent across the complete glazing package.

Competitive Does Not Mean Basic

Seniors is often our go-to commercial system because it allows us to meet demanding project requirements without specifying more system than the building actually needs. That doesn’t mean cutting corners. It means understanding where performance is required, choosing the appropriate system and spending the project budget intelligently.

Where a standard commercial system meets the specification, there may be little benefit in paying significantly more simply for a different name. Where the building genuinely requires something more specialised, we’ll say so.

Exceptional Thermal Performance When It Matters

One area where Seniors really stands out is its PURe® range. Rather than using a conventional thermal break, PURe incorporates an expanded polyurethane thermal barrier within the aluminium profile, allowing exceptionally low U-values to be achieved.

For most commercial projects, this simply provides another high-performing option within the Seniors range. For some domestic projects, however, it can become one of the deciding factors. If achieving outstanding thermal performance is one of your highest priorities, the PURe range may be the right solution for your home.

Why We Specify Seniors

Seniors has earned a strong reputation throughout the commercial construction industry because it offers proven, dependable aluminium systems across virtually every part of a building. We manufacture and install the complete Seniors range, allowing us to specify the right system for each project rather than trying to make one product do everything.

The system should always be chosen to suit the building, not the other way around.

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
