Andrew Cooper of Senior Architectural Systems says architects can embrace principles of biophilic design and wellness, while keeping regulation compliance clearly in view.
As well as being functional, fenestration systems can help create truly inspirational interiors where inclusivity, wellbeing, and comfort are prioritised, and where the natural environment is always at the forefront.
Greater use of natural light, wider views of the outdoors, and easier access to external areas are all recognised as having a positive impact on the health and wellbeing of building occupants. However, this must be balanced with the operational cost – both monetary and environmental – of incorporating large amounts of glazing.
The WELL Building Standard places strong emphasis on creating healthier indoor environments, and there are several areas where the correct design of aluminium fenestration systems is essential. These include access to natural light, quality views of the outdoors, thermal comfort, and enhanced ventilation. Meanwhile, both the updated Building Regulations and Passivhaus standard require buildings to achieve exceptional levels of energy efficiency and thermal performance, with strict criteria for airtightness and heat loss.
Through early and close collaboration within the supply chain, the most appropriate solutions can be found to create stunning fenestration designs that provide optimal daylighting, reduce energy demand, and boost occupant comfort, while supporting key biophilic design principles.
Aluminium fenestration systems offer a number of practical and environmental benefits that make them a reliable choice for both contemporary and biophilic design schemes. The inherent strength of aluminium enables larger panes of glass to be supported by slimmer frames, allowing more natural light into the building while maintaining structural integrity. This is particularly advantageous when creating open, light-filled spaces that foster a deeper connection with the surrounding landscape.
Aluminium is also one of the most sustainable materials in use today. It can be recycled repeatedly without any loss of quality, and many manufacturers are working to improve the availability of recycled material in the UK.
Opening the curtains to nature
Aluminium curtain wall systems continue to offer architects a versatile way to create striking facades that strengthen the visual and physical connection between interior spaces and the outside world. Whether used across full-height elevations or as feature areas, curtain walling is an effective way to maximise views, increase daylighting, and bring a sense of openness to a building.
Slim sightlines are key to achieving these benefits, as they reduce visual barriers and allow for a greater expanse of glass. Alongside this, thermal enhancements to both the frame and glazing can support energy-efficiency objectives by reducing heat loss during colder months. The inclusion of solar shading or louvre systems can also help prevent solar gain and overheating during warmer periods, creating a more consistent and comfortable internal climate throughout the year.
Door systems & access to outdoor spaces
Aluminium door systems provide a flexible way to meet a variety of access needs while contributing to the overall building performance. Options such as sliding or bi-fold doors help to open up interior spaces and create seamless transitions to external areas, supporting outdoor learning, working, or leisure activities, and further enhancing the sense of connectivity with nature.
Commercial entrance doors, particularly those designed with robust glazed panels, also contribute to improved daylighting in communal or high-traffic areas. With the availability of different threshold types, inclusive access can be more easily achieved without compromising on thermal performance.
In refurbishment or heritage projects, traditionally styled aluminium doors offer a sympathetic design solution while delivering modern performance standards. This allows older buildings to meet today’s requirements for energy efficiency and accessibility while preserving their architectural character.
Window systems & thermal performance
Windows play a vital role in both the design and environmental performance of a building and it’s important to look for a system that offers exceptional thermal efficiency but is also available in a range of different opening styles. Given the proportion of a building’s energy that can be lost through poorly performing windows, ensuring compliance with Part L and achieving low U-values are crucial steps in reducing operational carbon.
As sustainability becomes more deeply embedded into both the regulatory and practical requirements of modern architecture, aluminium glazing systems are playing an increasingly pivotal role.
