About Knauf

The successful development of the Knauf UK business started in 1988 with the construction of our first plasterboard plant in Sittingbourne, Kent. A second plasterboard plant at Immingham, N.E. Lincolnshire, and a plaster plant at Sittingbourne closely followed. To date, in excess of £100 million has been invested in the most advanced manufacturing technology making Knauf one of the largest suppliers of gypsum-based building materials in the UK.

Knauf is firmly committed to on-going technology developments and diversification, working closely with the industry to deliver quality, innovative, cost-effective products to our customers. Knauf systems have been used and installed around the world with proven success. In the UK, products have the quality assurance of the Company’s BS EN ISO 9001:2000 certification.

To ensure that this success continues into our second decade, we are not only working to continually improve the quality of current products and services, but constantly monitoring and evaluating trends for new materials, technologies and systems. In this way we can identify and develop each new opportunity to maintain our leading edge position.

The Knauf Group

Knauf, a family name, and a corporate group of global dimensions. At the same time synonymous with a type of corporate culture which has become rare. Knauf is a typical family firm in spite of its size and this is precisely the reason for its amazing success. It is the short and direct decision-making paths, the courage to tackle new ideas, innovations, investments and the wealth of ideas contributed by all Knauf employees that characterises the company.

Knauf was founded in 1932 by the brothers Karl and Dr. Alfons N. Knauf. Today their sons, managing partners Baldwin and Nikolaus Knauf, steer the success of the corporations’ numerous enterprises in close co-ordination with the other family members.

From its beginnings in gypsum processing along the Saar and Main rivers, Knauf has expanded and diversified to become a corporation with worldwide activities, delivering products and services in the following fields:

  • Building materials and systems based on gypsum and gypsum-related products
  • Thermal insulating and sound insulation materials
  • Limestone and lime products
  • Chalk and cement related products
