Wetherby Building Systems are proud to announce that they are the first EWI provider in the UK to gain BBA (British Board of Agrément) certification for a grey EPS insulation board to be used in conjunction with both silicone and dry dash render finishes.
Since the EpsiTherm board completed all BBA testing in May, the new BBA certification allows Wetherby to provide a fully approved external wall insulation (EWI)
solution utilising a graphite-enhanced EPS insulation board.
The new certification approves Wetherby’s EpsiTherm insulation board to be used with its Epsiwall (silicone) and Epsicon (pebble dash) systems for new and existing domestic and non-domestic buildings. The key factors assessed to achieve the certification were thermal performance, strength and stability, behaviour in relation to fire and risk of condensation.
There has been increasing demand for grey EPS insulation systems among housing associations, social housing providers and contractors as it thermally outperforms standard white EPS due to its lower K-value, meaning that lower thicknesses are required to achieve required U-values.
Epsitherm offers significant cost savings in comparison to alternative insulants, helping to keep project costs to a minimum and as a result, Wetherby have had an increase in enquires for a grey EPS solution and can now offer a fully approved system to meet this demand.
Joe Ragdale, technical manager at Wetherby, comments: “Gaining these BBA certifications reassures housing associations, local authorities and contractors that they are specifying an industry approved product. The demand from the industry for a system comprising of grey EPS is huge and we can now meet this with a fully approved system.”
