The Rise of Aluminium:
The Shift Changes in Modern Fenestration
For decades, the fenestration industry has continuously evolved, shaped by changes in architectural preferences, advancements in materials, and the growing demand for more sustainable and high-performing solutions. The latest shift, one that is transforming both commercial and residential projects, is the return of aluminium as the premium, go-to material for windows and doors. Where uPVC once dominated, aluminium is now reclaiming its position at the forefront of modern fenestration, driven by its strength, sustainability, and design versatility.
Astra Windows, a leading fabricator of high-quality aluminium windows, doors, curtain walling, and rooflights, has been at the centre of this transformation. For over 35 years, Astra has worked alongside the trade to supply superior fenestration solutions, evolving with the market and responding to industry needs. Today, as more installers and architects turn back to aluminium, Astra Windows is leading the charge, providing cutting-edge, installer-friendly systems that deliver durability, aesthetics, and energy efficiency without compromise.
A Shift in Fenestration History Aluminium was once the dominant material for windows and doors, favoured for its strength, slim sightlines, and ability to support large expanses of glass. During the mid-20th century, aluminium systems were commonly installed in homes and commercial buildings, appreciated for their robustness and modern aesthetic. However, the material had one significant drawback— thermal efficiency. Early aluminium frames conducted heat, leading to poor insulation, condensation issues, and higher energy costs for property owners.
The rise of uPVC in the late 20th century presented an alternative that, at the time, seemed like the perfect solution. uPVC frames were cheaper to produce, lightweight, and offered better insulation properties compared to the unbroken aluminium profiles available at the time. As double glazing surged in popularity and energy efficiency regulations tightened, uPVC quickly became the standard for residential fenestration.
However, as the industry advanced, so did its understanding of the limitations of uPVC. While it provided an affordable solution, it lacked the long-term durability, slimline aesthetics, and structural integrity of aluminium. Over time, uPVC frames could become discoloured, brittle, and prone to warping, particularly when exposed to extreme weather conditions. In contrast, aluminium has continued to develop, and thanks to modern innovations such as polyamide thermal break technology, it now delivers outstanding energy efficiency— eliminating the concerns that once led to the rise of uPVC.
Why Aluminium is Now the Clear Choice
As contemporary design trends lean towards larger glass areas, slimmer frames, and enhanced durability, aluminium has emerged as the superior material for modern fenestration. Its inherent strength allows for sleek, minimalist profiles, enabling more natural light to flood into living spaces, a crucial factor in today’ s architectural vision. Unlike uPVC, which requires thicker, bulkier frames for structural integrity, aluminium’ s high tensile strength means that the trade can achieve wider, uninterrupted views and a more refined aesthetic for their customers.
Beyond its aesthetic advantages, aluminium also stands out for its exceptional longevity. Aluminium remains resistant to warping, cracking, and UV damage, ensuring that installations maintain their quality for decades. Additionally, it is an
