"I have bought plenty of vapour barrier from Screwfix in the past. The previous stuff sold was a lighter green than this stuff but more importantly, it was strong! This stuff is very thin and perforates incredibly easily which is less than ideal, it being supposedly a vapour barrier.I was obliged to "double up" with this stuff to try to maintain integrity. So it takes double the work and by default costs double the price as well. This stuff is total rubbish and not fit for purpose - buy something else."
