Drywall systems that meet all your application and construction needs. Innovation, ease of use and integration go together to provide powerful, high performance and simple-to-implement solutions across all building sectors.
An introduction to Knauf Drywall Systems
Knauf Performer
The Knauf Performer system is our most versatile and commonly used partition system. It is constructed using a single row of Knauf metal studs with Knauf plasterboards to both sides in order to meet fire, acoustic, moisture and impact requirements. The Performer system is lightweight, simple to construct and should be used in conjunction with Knauf’s finishing solutions range.
Knauf Performer with Knauf Resilient Bar
Knauf Resilient Bar can be added to both or one side of certain Knauf Performer systems. This additional component improves the acoustic sound reduction performance of the system in order to meet higher acoustic requirements
Knauf Isolator (Twin Frame)
The Knauf Isolator system is typically used to divide habitable dwellings. The twin stud build up, combined with Knauf’s high performance plasterboards, maximises acoustic performance in order to comply with building regulations, technical handbooks and guidances for sound insulation.
Knauf Silent Spacesaver (Staggered Stud)
The Knauf Silent Spacesaver system provides a high acoustic performance partition from a narrow footprint. Using a single row of Knauf Staggered ‘I’ Studs and clips, rather than a twin row of parallel metal studs, the Silent Spacesaver can optimise the available space within the building whilst still achieving up to 60dB (Rw) sound reduction.
Knauf Shaftwall
Knauf Shaftwall is our innovative system to form enclosures around service and lift shafts while working from one side. The unique Knauf ‘C-T’ Stud makes this possible with a minimum of components. The system can provide a high level of fire resistance performance to meet the requirements of your project.
Knauf ‘I’ Stud Linings (Free Standing)
Knauf Independent ‘I’ Stud is a fully independent wall lining system that can be used in all building types to upgrade the acoustic, fire and thermal performance of an existing masonry wall and to deal with any irregularities. Due do the system using an Knauf ‘I’ Stud, there is no requirement for the lining system to be fixed back into the structure behind.
Knauf AQUAPANEL® Cement Board Indoor Board / Interior System
Knauf AQUAPANEL® Cement Board Indoor is exceptionally tough and durable, providing a solid tile backing substrate for wet indoor areas such as swimming pools, leisure centres, bathrooms and kitchens. The board is used in conjunction with specialist screws and finishing products to provide a full Knauf solution for humid and wet conditions.
Knauf Metal Furring (MF) Suspended Ceiling System
The Knauf Metal Furring (MF) Suspended Ceiling system is versatile and easy to install. Deep voids are easily created to hide services and the ceiling can be used to provide fire protection to the soffit above. The Knauf MF Suspended Ceiling system is very familiar to contractors who will easily be able to form openings, bulkheads and coffers.

For nearly ninety years, Knauf has remained relentless, responsible and forward-looking in its pursuit of excellence.
We have grown our reputation through making sure we focus on the environments in which our products are employed – working together to develop the solutions our customers seek; challenging preconceptions of what is possible and always open to new ideas.
We recognise the importance of the buildings in which we all live, work and relax. We spend 90% of our lives inside buildings, so it is of the utmost importance that the homes we live in, the hospitals where we care for our sick, the schools in which we educate our children and the offi ces in which business operates are world class. Safe, comfortable, sustainable and enjoyable.
The extensive portfolio of products and systems from Knauf UK & Ireland is developed to support that vision.
As a business, we look to the future; building on the knowledge we have acquired with a planned programme of research and development to make sure we continue to keep ahead of current thinking. Experimenting, testing new solutions and working ever more closely with our partners at every stage of a building project: the designers, distributors, contractors and users to make sure the developments we work on are genuinely innovative, relevant and progressive.
Looking to the future also means that our business must be sustainable. We are always conscious of the wider
consequences of our actions, both today and tomorrow. In terms of our operation we work hard to minimise our impact on the environment and are proud of our recycling, waste reduction and energy effi ciency initiatives.
Furthermore, we recognise that our business is only successful if the people who work within it are supported, encouraged and inspired. Our employee development programmes ensure that every individual is offered the opportunity to learn and progress both professionally and personally. The result is an exceptional team.
Technical expertise is the foundation of our business, but this has to operate hand-in-hand with a secure focus on our customers. We work hard to ensure that our support, service and customer relations functions are responsive, accommodating and resourceful. We proactively seek feedback at every opportunity, ensuring our customers have a fast and easy route to pass on comment and suggestions which are then used to inform further development.
There is always more to do. Every business must continually improve to keep ahead. We are constantly evolving to meet new challenges and capitalise on new opportunities while never losing sight of our ultimate goal: to Build for the world we live in. Now, tomorrow and for the future.
Here at Knauf, we build for the world we live in
