What Senior Architectural Systems does

Senior Architectural Systems is a UK-based designer and manufacturer of aluminium and hybrid (timber-aluminium) fenestration systems, supplying windows, doors, curtain wall, shopfronts and roof glazing to the construction industry. The company is based in Doncaster and operates as a wholly-owned subsidiary of the Swedish access solutions group ASSA ABLOY, with a regional specification presence spanning the United Kingdom and the Republic of Ireland. Core technology centres on thermally broken aluminium profiles using polyamide and expanded polyurethane (PURe) thermal barriers, alongside a uniquely UK-manufactured timber-aluminium composite system and a zone-drained pressure-equalised semi-unitised curtain wall platform, achieving stated U-values as low as 0.93 W/m²K and weather performance tested to CWCT Sequence B.

The business runs a specification-driven B2B go-to-market, engaging architects and specifiers during project design through CPD presentations, BIM object libraries, and BREEAM compliance documentation, then distributing finished systems through a certified network of aluminium fabricators and glazing contractors who install on behalf of main contractors. Revenue is generated through project-based one-time sales of complete framing systems with hardware and accessories; pricing is quoted per project and is not publicly listed. Customer concentration is spread across Education, Healthcare, Commercial, Residential, and Hospitality/Leisure verticals, with named reference projects for NHS facilities, Hilton hotels, Sainsbury's, Leicester College and Vestas, among a portfolio of more than 100 featured installations.

Marketed product families include PURe, SPW/SPW+, SPD/SPD150, Ali VU, Ali SLIDE, Ali FOLD, SF52 curtain wall and the Hybrid range, all positioned as a fully compatible suite that allows single-source specification for an entire building envelope. Recent activity (2025-2026) has included new EPD releases, the launch of the SPD150 commercial-grade door, and a dedicated Architectural Advisor hire for Scotland and Ireland, consistent with continued mid-single-digit growth in a mature UK fenestration market.
