Fundamentals of Insulation


Fundamentally, insulation is one of the most important aspects of a high-performance house. But all insulation is not created equal! Each material has it’s own set of good and bad points when it comes to resisting heat flow, air flow, and moisture flow. There’s not a silver bullet, single material that is perfect for all parts of a house. Don’t get caught with your batts down!
