The Best Aluminium Windows and Doors, Professionally Installed
At Fenestration Studio, we work with the UK’s leading system companies and manufacturers to provide homeowners with the very best in aluminium windows and doors.
Our expertise spans decades in the glazing industry, giving us a complete understanding of how each system performs, what makes it unique, and where it fits best.
Whether you’re looking for architectural aluminium sliding doors, precision-engineered bifolds or beautifully crafted front doors, we can help take the headache away.
Our Expertise: Aluminium First, Always Balanced
We specialise in aluminium because it remains the benchmark for strength, style, and long-term reliability. Slim sightlines, greater colour choice, and structural capability make aluminium the clear leader for modern bifolding doors, sliding doors, and large-format glazing.
However, we also understand that some properties — particularly heritage homes, timber-look designs, and rental developments — are better served by today’s latest uPVC systems.
Our role is to guide you to the best option for your project, balancing aesthetics, budget, and performance with honest, informed advice.
