What TruFrame does

TruFrame is a UK-based B2B fabricator of hand-finished uPVC windows and doors, operating exclusively through a network of trade installer and fabricator partners rather than direct to consumers. Founded in 1994 and headquartered at a 50,000 sq ft manufacturing facility in Melton Mowbray, Leicestershire, the company is positioned as the largest nationwide fabricator of Liniar uPVC profiles, with the Liniar extrusion facility located within 40 miles. Its product portfolio spans seven window types (Casement, French Casement, Flush Sash, 80mm Refine Flush Sash, Tilt and Turn, Sash Horn, and Vertical Sliding Sash using Spectus profiles) and five door categories (uPVC Residential, Composite, Stable, French, and Patio), all carrying BSI Kitemark, Secured by Design, and ISO 9001:2015 certifications.

The company generates revenue exclusively through hardware sales to trade partners at quote-based pricing, with no direct-to-consumer channel. Its go-to-market is built around exclusive territory protection — TruFrame will not supply competitors of an existing partner in the same geography — combined with dedicated Sales Manager support, a Customer Portal for 24/7 order placement and tracking, and a QuoteBuilder specification tool that drives homeowner leads back to installer partners. A secondary trade counter in Orpington serves the South East market. The business is founder/management-owned (David Firmager, Managing Director; Patrick Firmager, Marketing Director), with no disclosed external equity, and operates as a single private limited company (TruFrame Ltd) with no subsidiaries.

Operationally, TruFrame reports a 99.7% on-time delivery rate and recycles approximately 10 tonnes of uPVC per week. A £3.2 million CAPEX programme (announced 2017) deployed Urban AKS 1150 butt welders, Rotox EKA 574 CNC corner cleaners, and a new welding facility. The company partners with Liniar (profile supply), Yale and Ingenious (locking systems), and the Double Glazing Network (installer finder); its technology stack is conventional web-based rather than AI-enabled. Recent strategic activity includes a new composite door range launched in February 2025 and the Orpington trade counter expansion.
