Finstral UK Limited

Finstral UK provides premium, European-engineered window and door systems for high-end residential architecture. We help designers bridge the gap between ambitious creative concepts and strict technical realities. Our modular framing system allows you to freely combine different materials, meaning you can specify uPVC, aluminium, timber or engineered glass on the interior or exterior faces without compromising on thermal efficiency, acoustic control or structural performance.

Through our RIBA-approved CPD sessions and technical advisory team, we offer specifiers comprehensive detail support, detailed CAD data and clear guidance on building regulations. You can explore these bespoke systems firsthand at our Borehamwood Studio, which acts as a collaborative technical space rather than a retail showroom. To ensure your design intent is perfectly executed on-site, we directly connect your finalised specifications with our network of approved regional trade partners who manage the project through to certified installation.
