A lot of the issues appear to lie with the combustibility of the insulation blocks themselves - with this in mind does this mean there may well be serious issues with retro fitted external insulation to normal single/double storey houses that seems to be a currently popular way to insulate older dwellings that don't have cavity walls to fill (which brings its own issues i know)? My friend had theirs done last year - and to me it looked quite simply like blocks of grey polystyerene type material being glued, then drilled onto to the existing render and then simply rendered over. Not sure what the fire safety regs are on such things but even if they do "appear" to be compliant....as now seems to be coming out with the cladding on towers, they may actually not be!
A typical brick and timber dwelling is more combustible than concrete preformed flats (designed to self contain fires) - so the thought that my neighbours have clad their house in an external wick, is a tad worrying! and again - could this be a major issue in the domestic housing market too or does anyway know if such external insulation is completely different to those on tower blocks that are then cladded over??
