Smart Architectural Aluminium designs and extrudes its systems in Britain and is a member of Made in Britain. Everything has a polyamide thermal break, so you get slim frames without the cold, condensation-prone aluminium of years ago.

- PAS 24:2022 security across windows and doors
- Any RAL colour, dual colour available
