Glazing Gallery
Scotland's Aluminium Glazing Specialists Since 1978
Century 21 was founded in 1978 and has spent nearly five decades refining the art of aluminium glazing manufacture and installation. Serving both domestic homeowners and large commercial clients across Scotland, we bring depth of experience that generalist contractors simply cannot match.
From residential window replacements to curtain walling on commercial developments, our in-house manufacturing capability means shorter lead times, tighter quality control and a finished product that genuinely performs. Every project is handled by our own trained team from survey through to sign-off.
Systems from Smart, Cortizo and Finstral
We build our glazing systems around three world-class suppliers: Smart Architectural Aluminium, Cortizo and the premium Italian brand Finstral. Each system is rigorously engineered, thermally efficient and available in an extensive range of configurations to suit any architectural brief.
This means when you choose Century 21, you are not limited to a single system or a narrow product catalogue. We specify the right system for your project’s performance requirements, budget and aesthetic – then manufacture and install it ourselves, ensuring full accountability from start to finish.
