Knauf has achieved third party certification from the British Board of Agrément (BBA) for its Windliner Sheathing Board.

The BBA evaluates manufacturers’ products and systems, awarding certificates as recognition of the product’s quality and reliability for use in the marketplace. Knauf Windliner passed all tests, on-site evaluations and quality management checks, reassuring architects and specifiers of its use as an external sheathing board.

The certificate assessed Knauf Windliner on its strength and stability, confirming its credentials as an external sheathing material regardless of wind actions and racking loads. It has also been recognised for its reaction to fire, achieving a classification of A2-s1, d0 in accordance with British Standards. This gives no height restriction for its use when specified in a full system and tested in accordance with the BRE performance criteria.

In addition, the boards were recognised for their water resistance and weather-tightness during the construction phase and prior to completion of the external facade.
