Customisation and Finishes 

Aluminium boasts exceptional adaptability to suit your precise aesthetic vision. Colour options are virtually limitless, with powder coatings offering a durable, low-maintenance finish. Moreover, dual-colour options are available, allowing for different internal and external colours to complement your decor. 

Beyond colour, aluminium can be textured to mimic woodgrain effects or treated to achieve unique metallic finishes. As a result, your aluminium fenestration can seamlessly blend with your chosen aesthetic. 

Aluminium fenestration is not just for new builds! Due to its slim profiles and adaptability, it's increasingly used in refurbishment projects where it successfully mimics the look of traditional materials like steel or timber. This allows for improved energy efficiency and contemporary design solutions without sacrificing a building's historical character. 

Energy Efficiency and Sustainability Considerations 

Aluminium fenestration plays a significant role in improving the overall energy performance and environmental impact of buildings. Here's how: 

Thermal Efficiency 

One of the most crucial considerations for UK homeowners is thermal efficiency. While aluminium is a conductive material, modern aluminium fenestration incorporates a 'thermal break'. This is an insulating barrier, often made of polyamide, within the frame profile, dramatically reducing heat transfer. This results in minimised heat loss in winter and reduced heat gain in summer – ultimately leading to lower energy bills. 

Double (or Even Triple) Glazing Aluminium systems effortlessly integrate with high-performance glazing. Double glazing, as standard, and triple glazing in particularly demanding environments, create further barriers against heat transfer. Look for options with warm-edge spacer bars and gas filling (typically argon) between panes for optimal thermal performance. 

Assessing Energy Ratings 

Reputable aluminium fenestration suppliers provide independently-verified energy ratings, such as the BREEAM system or Window Energy Ratings (WER). These ratings take into account the entire window’s performance, including glazing, frame material, and thermal efficiency. Aim for 'A' or higher rated systems for the best energy savings over time. 

Sustainability 

Aluminium offers a remarkably long lifespan, with well-maintained systems lasting several decades. Moreover, aluminium is one of the most recyclable materials on the planet, with around 75% of all aluminium ever produced still in use today. This closed-loop material cycle minimises waste and reduces the environmental footprint of your building project. 

To ensure your aluminium fenestration aligns with your sustainability values, look for suppliers committed to ethically sourced aluminium and environmentally responsible manufacturing processes. Certifications such as BES 6001 or schemes like the Aluminium Stewardship Initiative confirm responsible sourcing.
