What Profix Window Systems does

Profix Window Systems is a UK-based fenestration manufacturer and installer headquartered in Tamworth, Staffordshire, operating under The Profix Group alongside subsidiary Grand Entrance Products. Founded around 1988, the company supplies a multi-material range of windows and doors spanning aluminium, PVCu, timber, alu-clad timber, and composite products to main contractors, housebuilders, architects, social housing providers, educational and healthcare institutions, and individual homeowners. Its go-to-market is sales-led and project-based, with both supply-only and full supply-and-install offerings executed from a single manufacturing site, supported by a #onecall single-source service model that bundles design advice, manufacture, installation, and resident liaison.

The product portfolio is anchored by the WarmCore aluminium range (fabricated under licence from Synseal Group) featuring a full-width orange thermal core delivering U-values as low as 1.0 W/m2K with triple glazing and 25% better thermal efficiency than traditional aluminium. The PVCu Pro-Therm range carries Window Energy Ratings of A-C with U-values down to 0.8 W/m2K and Energy Savings Trust endorsement. Residence 9 flush sash timber-replica windows serve the conservation-area specification market, while Grand Entrance Products manufactures composite entrance doors, the CE-marked Flame Door FD30 fire door, and Swing and Slide patio doors. The group holds an unusually broad certification stack including Secured by Design, PAS 23/24, BS 7412, BS 7950, BBA, BSI Kitemark, ISO 9001:2015 (covering installation), ISO 14001, and Construction Line approval.

Revenue is generated through one-time project contracts on a quote-based pricing model with no published price list. Customer mix spans enterprise construction accounts (Balfour Beatty, Kier Group, Countryside Properties, Birmingham Airport, Alcon Components) and a long tail of homeowner and SMB supply-only transactions, with social housing refurbishment and new build residential supply as recurring verticals. Distribution is regional/domestic, executed via direct field sales, dedicated account management, and phone-based quotation, with no disclosed geographic or channel expansion beyond the UK market.
