FEATURE
FIBREfon 8, is a high-performance fleece that, due to its cell structure and composition will compress more than the FIBREfon 10, therefore absorbing more impact energy imposed on the board. In tests we have undertaken, this results in an impact improvement of 4dB on both timber and concrete floors.
With timber and steel joists being a lightweight construction,
the base performance of the floor can be inconsistent, and we like to only specify systems that will comfortably exceed building regulations. This ensures confidence and consistency in all our systems and products and therefore the additional improvement on these lightweight cassettes is important to the system. Concrete floors have an enhanced base performance meaning the difference between the fleece and wood fibre is not as critical.
Alongside the performance differential on lightweight floors, Cellecta aims to have all our new build products covered by Robust Detail accreditation, again to give confidence in the quality of our products. To comply with FFT4 (floating floor treatment) on RD concrete applications, you need to prove that your product improves a base floor by 17dB – which we have done in an independent UKAS accredited lab, Sound Research Laboratories for both the 28 and 30mm board.
However, to have the proprietary Robust Detail on timber or steel frame, you need to undertake 30 sets of live site tests over at least four different sites – each of these tests need to exceed the Robust Detail performance criteria whilst having a mean average of +5dB across all tests. Not only can this take a few years, but it is also a very large investment for a manufacturer. If one single test does not meet the targets detailed by RD, then you must start again.
ScreedBoard 28 has undertaken this stringent test regime on three different floor types, gaining RD accreditation for timber i- joists (E-FT-5), metal-web joists (E-FT-6), and steel c-section joists (E-FS-3). It is the enhanced performance and consistency of the FIBREfon 8 on these lightweight floors that make it the ideal solution.
Furthermore, Cellecta, as a responsible manufacturer, is always looking for ways to make our systems the best on the market. We began to see a shift in build programmes, with drylining being undertaken after the floorboard was installed on concrete buildings. Therefore, introducing ScreedBoard 30 and the higher load capability of the product, meant more flexibility on site for the build programme.
There is also the scenario of acoustics in non-domestic applications such as schools or commercial properties. In this situation it may be prevalent to explore ScreedBoard 30 even on lightweight structures as the loads imposed could be higher than standard domestic loads outlined in EN 1991- 1-1. Having the flexibility to assess the acoustic, structural, and fire performance of a project and then having a solution for every scenario is one of Cellecta’s key strengths and our experienced technical team are on hand to help specifiers select the appropriate solution.
Both ScreedBoard 28 and 30 can also integrate underfloor heating systems. Separating the ScreedBoard 20 from the FIBREfon 8 or 10 resilient layer and inserting a layer of XFLO with ULTRAplate or XFLO FF, a foil faced routed extruded polystyrene ensures that all the benefits outlined in the

opening section of this document are coupled with unrivalled acoustic performance. The key aspect being that the resilient layer is inserted under the UFH pipes, so it does not have an adverse effect on outputs.
Due to a system-first approach that Cellecta prides itself on, this is then classed as our Mojave System, the ultimate underfloor heating and acoustic overlay, in which all the components have been independently tested. This offers a wealth of data giving confidence to specifiers, installers, and end users that they are utilising components of the highest quality backed up by full system data.
