Insulation, Vapor Permeance, and Wall Forgiveness

This week on The Build Show Podcast, Matt and Michael Crane go deep and nerdy into vapor transference and wall forgiveness. Michael Crane is a business development manager with Rockwool, and he and Matt talk about the importance of water and insect control when building. They also discuss how Rockwool products are environmentally friendly, repel insects, and can be used above and below grade. They touch on vapor open and vapor closed systems and detail out a perfect wall, walking through what that could look like. Interested in the white papers that Matt and Michael mentioned?
