VELFAC: bespoke composite windows and doors for UK homes

VELFAC is a UK-based supplier of composite wood-aluminium windows and doors, operating as a trademark of DOVISTA UK Ltd. The company focuses on domestic projects and offers a product range that includes the VELFAC 200, VELFAC Ribo and VELFAC Classic lines, covering both windows and doors. Its products are manufactured to exact specifications rather than standard sizes, and are sold exclusively through a network of distributors across the UK.

Product ranges and configurations

The window range comprises the VELFAC 200 with a slim frame, the VELFAC Ribo modern casement and the VELFAC Classic traditional casement, alongside inward-opening and tilt windows under the VELFAC In designation. The company also produces shaped windows, including triangular, corner, round, bay and floor-to-ceiling formats. Door options include sliding doors (VELFAC 200, VELFAC Ribo and VELFAC Signature), patio doors (VELFAC 200, VELFAC Ribo and VELFAC Classic) and front doors in flush, panelled and glazed styles, with customisation available for front doors.

Design and performance features

VELFAC emphasises a slim frame design that it states increases the ratio of glass in a window, letting in 25% more light compared with standard alternatives and reducing the need for artificial lighting. The composite construction combines aluminium externally with wood internally. The company also highlights energy efficiency, noise reduction, low maintenance and burglar protection as key benefits of its products. Glazing options include triple glazing, various glass choices, glazing bars, handles and restrictors, and panels. Colour options are available across both windows and doors.

Certification and warranty

VELFAC products are described as thoroughly tested and quality assured, meeting and exceeding necessary standards. Specific certifications mentioned include FSC® Certified Wood, Part Q compliance and Secured by Design. The company offers a 12-year warranty on its windows and doors.

Bespoke manufacturing and purchasing process

All VELFAC windows and doors are manufactured to exact customer specifications, including sizes, accessories, colours and opening functions. The company does not work with standard sizes and does not hold stock units. Purchases are made exclusively through VELFAC distributors, a UK-wide network of professionals selected for their product and technical knowledge. The buying process is outlined separately for homeowners and commercial clients, with guides, checklists and quotation steps provided.

Support and after-sales services

Customer service extends beyond delivery, with support for replacement parts, maintenance help and advice. The company provides installation guides, interface drawings, delivery and packing information, and a warranty claim process. Spare parts can be ordered, and a technical information section includes a product database, BIM objects, DoP documents, system drawings and structural drawings. Resources are also available for architects and designers, builders and developers.

Showroom and inspiration

VELFAC operates a showroom at NSBRC in Swindon and participates in exhibitions. A photo gallery showcases installed projects ranging from modern new builds to extensions and renovations, and a visualiser tool allows users to experiment with different door and window combinations on various house types.

Relationship with Rationel

Rationel windows and doors are now part of the VELFAC UK product range, available as VELFAC Ribo and VELFAC Classic. The company states that the same trusted products are offered under these new designations.
