Matt covers the story out of England regarding lenders rejecting homes with spray foam insulation. He highlights the importance of proper building science and insulation practices. The issue stemmed from older homes being retrofitted with spray foam insulation in the roof line, leading to moisture buildup and potential rot issues. The lack of a vapor barrier and inadequate insulation thickness contributed to the problem. This situation serves as a reminder for builders and homeowners to educate themselves on building science and ensure proper insulation practices, especially in colder climates. It also emphasizes the need for thorough research and a critical approach to building practices to minimize risks and ensure longterm durability.
