Knauf, one of the
world’s leading manufacturers of lightweight building products and systems, has
achieved third party certification from the British Board of Agrément (BBA) for
its Windliner Sheathing Board.
The BBA evaluates
manufacturer’s products and systems, and awards certificates as recognition of
the product’s quality and reliability for use in the marketplace. Knauf
Windliner has passed all tests, on-site evaluations and quality management
checks, reassuring architects and specifiers of its use as an external
sheathing board.
Paul Tollervey, Head
of Technical for Knauf UK, said: “In gaining a BBA certificate for Knauf
Windliner it demonstrates Knauf UK’s investment in quality production and its
ability to provide clients with a third party accredited product. This has been
a vital ingredient for us to help ensure acceptance with specifiers, building
control, local authorities and insurers.”
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, Knauf
Windliner boards have been recognised for their water resistance and
weather-tightness during the construction phase and prior to completion of the
external façade. Finally its durability was assessed, determining that the
boards have an expected service life equal to that of the building in which it
has been installed.
Knauf Windliner has
been designed to protect buildings against weather as part of the exterior
façade system. It can be used as the outer face to the Knauf Solid Frame System
(SFS).
The boards are
lighter than traditional cement particle board, allowing for easier handling on
site and faster installation times. Manufactured from gypsum rather than
cement, boards can be manipulated on site by simply scoring and snapping to the
required size and shape. Speed of construction is even further accentuated
because the boards require no specialist fixings and no pre-drilling is
necessary.
Used on numerous
construction projects throughout the UK and Europe, Knauf Windliner provides
the ideal solution for architects and contractors seeking an external sheathing
board that will protect their buildings regardless of the elements.
