What Comar Architectural Aluminium Systems does

Comar Architectural Aluminium Systems is a UK-based aluminium systems house that designs and extrudes over 700 aluminium profile sections used in commercial and residential windows, doors, curtain walling, window walling and ground floor treatments. Founded in 1970 and operating under Bailey CW Limited, the company has been in continuous operation for more than 55 years and is headquartered in Mitcham, United Kingdom. Its core technical platform is the proprietary P.i. (Polyamide Insulation) thermal break technology, used across the Comar 5P.i, 7P.i and 9P.i ranges to deliver progressively higher thermal performance — culminating in the Passivhaus-certified Comar 10 with U-values as low as 0.66 W/m²K, and the 2025-launched Therm-L+ Systems made from 70% recycled aluminium.

The product portfolio spans entry-level thermally broken casement windows (5P.i ECO/ECO+), high-performance windows (5Pi Advanced, Comar 10), commercial and residential door systems (Comar 7 non-thermal, Comar 7P.i variants including CD swing, LS+ lift slide, FSDX bi-fold, ECO rebated, and Comar 9P.i rebated doors), curtain walling (Comar 6 and Comar 6EFT) and ground floor treatment systems. All products carry third-party certifications including PAS 24, Secured by Design, BS EN 1627-1630 Level 3, ISO 14001:2015, BES6001, and CWCT compliance.

The business model is B2B systems-house distribution: Comar extrudes profiles and sells them to a nationwide network of approved fabricators who handle manufacture, installation and on-site delivery. A team of specification consultants supports architects directly with design, thermal calculations, NBS specification and BIM-ready design details. Customer end-markets are diversified across retail, hospitality, healthcare, education, residential, public sector and aviation — evidenced by projects such as the £2.6M West Hampstead Square residential scheme, the £50M Park Regis Hotel Birmingham, and the £10.2M Farnborough Airport terminal. Pricing is project-based and not publicly disclosed.
