Sample answer
“In my previous role, I worked extensively with fiberglass and spray foam insulation. I prefer spray foam due to its superior thermal performance and air sealing properties, which I found particularly effective in older UK homes. For instance, on a recent project in Manchester, we used spray foam in a Victorian terrace, leading to a 30% reduction in heating costs for the homeowner. I always ensure to follow safety guidelines when working with these materials, wearing proper protective equipment and ensuring adequate ventilation.”
