Reuben recently received a message from a podcast follower who encountered an insulation scam. He shares that the company reportedly had a free dinner and offered multi-layer insulation and solar-power attic fans that are supposed to fix iced dams. Tessa highlights the red flags about the products. 

Reuben describes and defines the products and their cost. Tessa shares the code requirements and how insulation should be installed and worked. She discusses the building science of insulation in different climates. 

Tessa recommends reaching out to the Minnesota Building Performance Association for a list of contractors.
