One listener asks about ZIP sheathing versus Smart Vapor Retarder for cold climate tongue-and-groove ceiling in terms of airtightness and moisture control (with a vented attic). Another listener starts with a specific question regarding zero-threshold exterior doors that leads into a pretty thorough discussion of Universal Design. This listener questions-driven episode wraps up with a great discussion of wood-based alternatives to concrete foundations/basements with some pressure on Steve and Jake to state if they would use any of these systems in future projects. The kicker though was the listener identifying Extreme Panel Technologies below-grade SIP systems using FDN (cca-treated) plywood and none of the boys knew anything about this system. Don't go home without checking the slew of great resources below! Huge thanks to our episode sponsor, Diamond Kote. Learn more at: https://diamondkotesiding.com/
