Knauf Brio Dry Floor Screed

Subcontractors installed soundproof flooring eight weeks ahead of schedule at Exeter University using the Brio system of dry floor screed boards developed by Knauf Drywall.

Project case study looks at how Knauf Briocut labour costs and avoided risk of delays to other trades on Opal 1, the £7.2 million development by Ocon Property Group for Exeter University.

  • four timber-framed buildings of three or four storeys
  • accommodation for 219 students, in self-contained studio apartments and flats with four or five bedrooms 

Mec-Serv, the Bristol-based screeding and acoustic flooring specialist, chose Knauf Brio Dry Floor Screed, enabling them to reduce their element of the Opal 1 build programme by eight weeks.

  • traditional wet screed was not an option on the 4,141m2 project because time taken to lay and dry properly
  • tight completion target and could be no risk any delays as the accommodation had to be ready in time for the start of the academic year

Knauf Brio Dry Floor Screed

  • perfect solution for the upper floors
  • met developer’s quality standards
  • ensured compliance with Building Regulations Part E
  • ensured minimal noise intrusion from the rooms above and below, particularly from footsteps

Brio AcousticFloor

Brio Dry Floor Screed system includes Brio AcousticFloor – two gypsum fibreboard panels that incorporate a 10mm wood fibre backing – so Mec-Serv chose Brio 18WF, laying the 18mm board over flooring grade polystyrene.

There are four Knauf Brio boards:

  1. Brio 18 (standard 18mm thick)
  2. Brio 23 (reinforced 23mm – recommended for underfloor heating applications)
  3. Brio 18WF
  4. Brio 23WF

The Brio WF (wood fibre) products are specifically developed to be an effective floor treatment as part of an acoustic separating floor with no need for timber battens.  Over timber, the footfall insulation improvement with this specification is up to 13dB, with up to 19dB over concrete. When laid on a level substrate, Brio WF gives up to 9dB over timber and up to 17dB over concrete.

Other Knauf Brio benefits

  • much lighter than traditional wet screeds
  • significantly reducesloads and costly structural requirements in multi-storey buildings
  • ideal for refurbishments because of its low installation thickness of just 23mm
  • board is thermally transparent and so works well with underfloor heating systems because any change in temperature is swift – there is no thermal mass to heat
