UnBuild It Podcast

Listener Wes asks about radiant barriers (Pete goes way deep on this one...); listener Chris G wants to know if there is a "perfect" (ala Joe Lstiburek) shower wall (with Pete responding he had just taken a shower that had a "perfect" wall); listener Howdy (dubbed so by Jake 'cause we did not have his name) from Climate Zone 3 asks about new construction, unvented roof assemblies (including a Lstiburek "perfect" roof with only topside rigid insulation); and finally British Columbia listener Harpreet asks about what sort of WRB to use with structural wall sheathing that is almost always damp.
