PAS9980 surveys permanent measures

  • PAS survey recommended remediations:
    (a) Recommendation that the Rockpanel Cladding and combustible PIR insulation are removed and replaced with materials which achieve Euro class A2 or better and the installation of cavity barriers in accordance with manufacturers recommendations.

     

    (b) Recommendation that the Brick Slip Cladding and the combustible PIR Insulation are removed and the combustible PIR Insulation is replaced with materials which achieve Euro class A2 or better and the installation of cavity barriers in accordance with manufacturers recommendations.

     

    (c) (Block 1) The acrylic render is of limited combustibility and will not support the spread of fire across the external façade. However, the 10mm render is of insufficient thickness so that if involved in fire the heat will cause the render to split and crack exposing the EPS insulation to fire. It is recommended that the Acrylic Render and EPS Insulation be removed and replaced with materials which achieve Euroclass A2 or better and that cavity barriers are installed in accordance with manufacturers recommendations

     

    (d) Replace combustible timber decking and associated combustible materials with materials that achieve a Euroclass rating of A2 fl – s1 or better

     

    In summary, the complete external façade needs to be removed and replaced with materials less likely to combust and to include cavity barriers to limit the spread of any fire.
