40 + years experience in the rigid polyurethane (PUR) foam industry in Canada and the United States. Born and raised in Canada, educated (Chemical Engineering) at Toronto's Ryerson University and considered a spray applied PUR subject matter expert by many. I have worked in various positions from Formulation Development Chemist to Business Manager and Vice President of Building Science for some of the most recognizable names in the industry, BASF, Demilec, Honeywell and Huntsman among them. I'm an independent consultant who understands the value of the building envelope and the energy conservation measures associated with it. Check out the website for further details.
