SPS Envirowall external wall insulation systems are fundamentally different from the ACM cassette rain screen cladding system which appears to have been used on Grenfell tower. Where required, the SPS Envirowall systems have undergone full scale fire tests. SPS Envirowall as well as organisations such as BRE and Warrington Fire Research are familiar with how EWI system generally perform in relation to fire and as such do not present a threat to the occupants within buildings clad with our EWI systems.
Over the many years these systems have been used, there have been incidences of fires in individual flats where SPSE and other similar external wall insulation system have been applied. It is our understanding that in each case fire damage to the cladding has been limited to the localised area of the fire, which is reflective of what occurs when we carry out a full scale test of our system. In summary, in both tests and actual fires, from our experience the fire does not spread across the building and damage is localised to the immediate source of the fire.
