90mm Recticel Eurowall® + is a premium, high performance full fill insulation board with precision cut tongue and groove joints on all four sides. This ensures that the boards lock tightly together minimising heat loss through thermal bridging. This unique joint offers increased protection against wind driven rain as well as improved wind tightness. Eurowall® + is also designed with a 10mm cavity requirement in mind, so that space can be left for conventional bricklaying techniques.

90mm EUROWALL+ within a 100mm cavity can help achieve a U-value of 0.18 W/m²K, meeting the requirements of Part L1A England 2013 and Part L1A Wales 2014. This means that existing designs can be maintained avoiding increased building footprints or reduced room sizes.

It has a grey alkali resistant facing against the inner leaf and a low emissivity multilayer aluminium facing on the front face that delivers improved thermal resistance within the cavity airspace.

  • Good thermal performance: λ = 0.022 W/mK
  • Tongue and groove joints on all 4 sides - easy and fast installation
  • Can help to achieve 0.18 U-value in 100mm cavities
  • Tongue and groove rebate minimises thermal bridging
