Nice man. Research done on insulation in cavity walls; fine. The product sold itself to me because I already knew what I wanted. If that had not been the case, I do not know whether the information provided had convinced me. A 'good story' can, in my opinion, be better supported by hard facts and the results of scientific research. Point of attention; there is no mention of the finish that you have to do yourself once the insulation has been applied. Only a day later did I realize that the story is not ready when they leave :-))
