An overview of Knauf AQUAPANEL® Cement Board


Knauf experts, Mark Sandford and Richard Lord, discussed the benefits of AQUAPANEL® at the Knauf Clerkenwell showroom during Clerkenwell Design Week 2021.


The Knauf AQUAPANEL® range of cement boards includes products for inside and outdoors, that offer significant performance advantages for all types of building.


The boards themselves have an aggregated Portland cement core with coated glass fibre mesh embedded in the front and back surfaces. Their edges are rounded (EasyEdge™), reinforced and finished smoothly.


AQUAPANEL® boards are 100% water-resistant; they are resistant to moisture, weathering, mould and mildew. They do not contain any organic matter so do not swell or change shape and they are dimensionally stable so there is no movement or cracking. The boards are non-combustible and impact resistant. They can also be curved with a bending radius of 1m at full board size.


The boards are safe and hygienic to use, they can be scored and snapped minimising dust and negating the need to take mechanical tools on site.

Moving away from building with brick and block, and building instead with an AQUAPANEL® Outdoor boarded cladding system has several benefits for all stakeholders:

  • Architects – provides greater design flexibility to create curved lightweight structures.
  • Building merchants – lightweight and stackable, and can be carried on smaller lorries for delivery
  • Contractors – less storage required than brick and block equivalent, and can be left outside or even on scaffolding
  • Installers – it’s lightweight and easy to use, easily cut and no pre-drilling required
  • Building owner – an AQUAPANEL® exterior with render increases internal floor space by 5% compared with using a block and render finish


Knauf AQUAPANEL® Cement Boards have been used in a number of high profile building projects including the London Olympic Stadium, the Iceberg Skating Palace at the Sochi Olympics and the Audi Ring in Frankfurt. What could it do for your project? Visit the Sochi Olympics case study:
