Good comments and this looks like a possible loophole in material specification that has already been detected 'across the pond' and rightly vetoed! I'd luv to read the spec for this cladding because there is still a distinct possibility that it's spec reveals that it is a fire hazard that should at least have been 'flagged up' for attention! As the saying goes - 'The devil is in the detail' and what is the material!? Polyethylene has alarmingly been mentioned and that would explain a lot if confirmed to be true!! The comment that it was 'aesthetically pleasing' is mind-boggling TBF! Also I must emphasise that The Client can specify the fire resistant integrity of all materials or certain materials deemed necessary in the contract document anyway and go beyond any 'middle of the road' iffy spec - all in the name of setting out a more robust document with tenant safety and fire safety paramount within the whole contract! Call it being proactive and forward thinking!
