In this episode of The Build Show, Mike from Greenside Design Build takes us inside one of his custom homes to break down the Flash and Batt insulation system. Mike explains how a layer of closed-cell spray foam—applied to walls and the roof deck—pairs with Rockwool batts to deliver high R-values that meet Chicago’s new energy codes. He also discusses the benefits of insulating the entire building envelope, including sound-dampening Rockwool batts for interior walls, and shares practical tips for clear jobsite communication through color-coded materials. With insights on moisture control, vapor permeability, and installation details, this episode offers valuable takeaways for builders focused on energy efficiency and comfort.
