Who Are Senior Architectural Systems?

Senior Architectural Systems PURe sliding doors in a new home

Based in Doncaster, Senior Architectural Systems is one of the largest fenestration systems companies in the UK.  Senior’s innovative products have been at the forefront of the glazing sector for many years. Founded in 1991, the company is one of the most respected systems companies in the industry, offering a range of high performance aluminium window, door and curtain wall systems.

One of the UK’s most innovative aluminium systems companies

Innovation is at the heart of Senior Architectural Systems. The company was the first to colour its own profiles, where previously external colour applicators were used. The PURe window was also the first window on the market to move away from traditional methods of insulating aluminium profiles and use a polyurethane thermal barrier to give the best possible U-Values to an all-aluminium window. Senior Architectural Systems has continued to stay ahead of the curve within the industry and develop game changing futureproof products that their customers can use with confidence. The company’s innovative spirit was recognised in 2023 when Senior Architectural Systems won the ‘Innovation’ accolade at the Morgan Sindall Supply Chain Awards!

Aluminium commercial doors and windows

Senior Architectural Systems provides high-quality solutions for developers and the glazing trade with a complete range of products.  Senior’s door and window systems are easy to specify, fast to install and provide a one-system solution for schools, hospitals, care homes, shops, offices and commercial developments of dwellings.

Senior’s aluminium systems are tested to the latest performance requirements with most having the best security ratings in line with official testing institutes and organisations. They are also tested for excellent weather protection and are created with thermal break technology for optimal energy efficiency that complies with updated Building Regulations.

For those seeking products for the commercial sector, Senior shopfronts and commercial doors are a staple of shops, schools, offices and other commercial buildings all over the UK. Their reliable commercial doors are some of the best and most trusted, providing security when closed and reliable access and exit when open. 

Why we choose Senior Architectural for our customers

At C&A Window systems, we fabricate the Senior Architectural Systems range of windows and doors range for our trade customers and their commercial projects.

For commercial doors, Senior Architectural Systems insulated and non-insulated versions provide a quality solution for high-traffic doors with none of the complexity of other systems.  At the same time, these products are easily modified to suit more demanding requirements such as fire-exit doors and automatic entrance doors.  

The window range is perfect for cost-effective housing projects, schools and offices where budget and lead times are essential, yet ideal where the building user still requires excellent security, low U-Values and attractive, reliable products. 

For those seeking a more bespoke glazing solution, we can also offer an aluminium curtain wall system from Senior Architectural Solutions; comprising of floor-to-ceiling picture windows, this curtain wall system allows for plenty of natural light and stunning, expansive views.
