115mm 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.

115mm 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.

  • 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
  • Fire performance: Class 1 (BS 476, Part 7)
  • Moisture tolerant
  • 1200mm x 460mm max including tongue and groove joint
  • 1190mm x 450mm installed dimensions

    What is Celotex PIR Insulation Board?

    Celotex is a brand of Polyisocyanurate (PIR) insulation board - a type of rigid foam insulation board backed with a foil layer, ideal for its exceptional thermal performance. It is a strong and light type of foam insulation board that keeps structures warm by trapping air inside. PIR insulation is lightweight, durable, and offers excellent fire resistance and thermal insulating properties, making it a super DIY-friendly solution that can easily be cut to size to fit rafters, joists and stud walls, and used as Cavity Wall Insulation. We also sell a Celotex PIR Insulated Plasterboard which is ideal to save time in stud wall applications. 

    How to Install Celotex Insulation Board

    Due to it’s versatile nature, there are many different uses for PIR Insulation and therefore many different ways to correctly install it. However, generally PIR insulation should be purchased to fit the depth of the cavity or space it is to fill. It can be cut to size to fit the height and width of cavities, joists and rafters using a sharp utility knife or handsaw for thicker boards. It is typically designed to be friction-fit to a space, meaning the boards should fit tightly and stay easily in place with no additional fixtures and fittings.

    For precise installation instructions for your specific use case, it is recommended to consult your builder, architect or building inspector to ensure installation complies with building regulations. 

    Celotex vs Recticel

    Celotex and Recticel are both brands of foil-faced PIR Insulation board available in a range of thicknesses. They are comparable products made from similar materials and methods and from a construction perspective they have the same Fire Rating (Euroclass F Reaction to Fire classification, according to BS EN 13501-1)  and thermal conductivity value of 0.022 W/m.K and so are suitable for largely the same purposes and projects.
