EWI Systems for Recladding Projects
In the wake of the Grenfell Tower tragedy, the UK Government amended the Building Regulations to prohibit the use of combustible materials in the external walls of residential buildings with a floor height of 11 metres or more. The decision followed a detailed review of fire safety, and it applies to all such properties in England containing at least one dwelling.
The change in policy has prompted many building owners to commission recladding projects. The work entails stripping out non-compliant rainscreen and insulated render products and replacing them with systems that achieve a European Classification of at least “A2-s1, d0”.
These classifications are taken from BS EN 13501-1 “Fire classification of construction products and building elements. Classification using data from reaction to fire tests.” No other fire test methods or national classifications are recognised when specifying materials for residential buildings of this type. As we explain in our section on Fire Safety, BS EN 13501 is the only route to compliance.
Strip & Reclad Projects
Since the introduction of the Building (Amendment) Regulations 2018, Permarock Mineral Fibre EWI systems have been used on recladding schemes throughout Britain. Examples can be viewed in our Case Studies section.
