What VELFAC does

VELFAC is a UK manufacturer of premium bespoke composite windows and doors, operating as a brand of DOVISTA UK Ltd within the DOVISTA group, which describes itself as Europe's largest supplier of windows and doors. Founded in 1952 and headquartered in Huntingdon, the company sells its signature aluminium-exterior / pine-interior composite system under product ranges including VELFAC 200 (flagship), VELFAC Ribo, VELFAC Classic, VELFAC In (inward-opening tilt-and-turn for multi-storey), and VELFAC Signature sliding doors, alongside patio, front, bi-folding and aluminium commercial doors and fire-rated elements.

The core technology centres on a slim-frame composite construction — aluminium extrusion alloy (EN AW-6060 or EN AW-6063) externally with VACUMAT or Flow-coat-treated pine internally — and argon-filled glazing cavities enabling U-values down to 0.8 W/m²K for triple glazing. The slim frame increases daylight entry by approximately 25% versus standard alternatives. All products are made to order to exact specifications; no standard sizes or stock units are held. Supporting digital infrastructure includes NBS Source specification listings, Autodesk Revit BIM objects, a WindowMaster motorised-window integration and an online Visualiser tool.

VELFAC operates a dual-channel go-to-market model: domestic and single-house sales flow through a UK-wide network of trained distributors providing site survey, installation and aftercare, while commercial and large residential projects are handled by direct sales supported by approved installers. Pricing is bespoke and quote-based. End customers span individual homeowners, architects and specifiers (supported by a Specification Team and 360° consultancy), builders and developers, and the distributor network itself. The business carries a dense stack of compliance certifications (FSC, Part Q, Secured by Design, Q-Mark, PAS 24, CE/UKCA, ISO 9001, ISO 14025 EPDs) and a 12-year window / 5-year door warranty.

Direct peers

• Rationel: Rationel is the sister brand of VELFAC within the DOVISTA Group, offering composite, alu-clad, and timber windows and doors for both contemporary and traditional projects. Same parent, same composite technology platform, distributed through the same UK VELFAC distributor network.
• Origin: Origin is a UK manufacturer of premium aluminium bi-fold doors, windows, and entrance doors, operating a direct-to-consumer and trade installer model. Comparable to VELFAC on premium positioning, bespoke sizing, and architect/specifier engagement in the residential and light commercial market.
• VELUX: VELUX is the global leader in roof windows and skylights, with a strong UK presence in premium residential windows. While VELFAC's focus is on composite windows/doors and VELUX on roof glazing, both compete for the same premium homeowner and architect specifying windows in new-build and renovation projects.
• Internorm: Internorm is a leading European manufacturer of premium aluminium-wood composite windows and entrance doors, with a strong UK footprint. Directly comparable to VELFAC on composite construction, bespoke manufacturing, energy performance claims, and architect/specifier-led go-to-market.

Emerging players

• Solidor: Solidor is a UK manufacturer of premium composite entrance doors, competing with VELFAC in the front-door and entrance category. Focused specifically on composite doors rather than full window/door ranges, making it a niche adjacent competitor rather than a full-line rival.

Broad incumbents

• Anglian Home Improvements: Anglian is a major UK home improvements company selling windows, doors, conservatories, and more via direct sales. Overlaps with VELFAC in replacement windows and doors but competes on volume and convenience rather than premium composite engineering and architect specification.
• Reynaers Aluminium: Reynaers is a leading European aluminium systems supplier for windows, doors, sliding doors, curtain walls, and roofing. Comparable to VELFAC on aluminium composite construction and commercial-grade specifications, but with a broader product range spanning residential and large commercial projects.
• Schüco: Schüco is a large German manufacturer of aluminium window, door, and façade systems with a strong UK commercial specification presence. Comparable on aluminium composite technology and commercial project capability, but operates across a much broader product portfolio including curtain walling and façade engineering.
• Everest: Everest is one of the UK's largest home improvements companies, offering windows, doors, conservatories, and roofing through a direct-sales and installation model. Competes with VELFAC in the replacement window/door market but operates at mass-market price points and broader product scope rather than bespoke premium composite.

Others

• DOVISTA Group: DOVISTA is the parent group of VELFAC and Rationel, described as Europe's largest supplier of windows and doors. Included for context: VELFAC's strategic, capital, and supply chain decisions sit within DOVISTA's broader European portfolio of window and door brands.
