What Epwin Window Systems does
Epwin Window Systems is a UK-based manufacturer and supplier of PVC-U and aluminium window and door profile systems, headquartered in Telford, Shropshire. The company operates as a multi-system house across three core product platforms: Profile 22 PVC-U (including the award-winning Optima range), Spectus PVC-U, and Stellar Aluminium, complemented by the PatioMaster sliding door range and ancillaries such as curtain walling and composite door outer frames. Technically, Epwin's differentiation rests on multi-chamber profile architecture (6-chamber outerframe, 5-chamber sash), Recycled Composite Material (RCM) thermal inserts made from 100% recycled PVC-U, an internal fitting system for high-rise refurbishment, and the patent-approved Stellar Slimline Bifold Door. The portfolio targets U-values as low as 0.8 W/m²K and WER ratings up to A++, with PAS24:2022 security compliance.
The business operates a B2B2C model: profile systems are sold to a network of approved fabricators and installers who manufacture the finished windows and doors and deliver them to end customers, supported by the 'Excellence as Standard' installer programme and the digital Connect Trade Portal. A separate commercial sales team engages directly with housing associations, local authorities, contractors, architects and specifiers on larger projects, providing free design, BIM/NBS specification support, site surveys, and tender documentation. Pricing is not publicly disclosed. Select customer evidence is concentrated in UK social housing refurbishment (Solihull Community Housing, Arawak Walton, People First, Home Group, Golding Homes, Kirklees Council), supplemented by education (Leeds University, St Cecilia's RC High School), healthcare (Leighton Hospital) and private residential (Westcliffe Court) projects.
Epwin Window Systems is a private, wholly-owned subsidiary of Epwin Group Plc. The company has accumulated a wide set of trade and sustainability credentials — VinylPlus Product Label (first UK systems house), BES 6001, ISO 50001:2018, ISO 14001, QUALICOAT (including Seaside) — and operates an active multi-channel marketing presence including headline sponsorship of the G Awards. In 2022 the company extended its Stellar Aluminium paint plant and expanded extrusion capacity by over 40%, and between 2022 and 2024 launched the PatioMaster Triple-Track Door, Stellar Inline Sliding Door, and Stellar integrated cill.
