79 - Q&A April 2023

Listener Steve C--mitered corners on cladding (plus "Trust But Verify" t-shirts!); listener Jason L--detailing Huber ZIP-R at window openings; Listener Dan--worry over window details with ZIP-R; Listener Jeff (who buttered us up with his love for UBIP)--cavity fill rockwool or CCSPF in retrofit and if CCSF can it be the WRB/can new OSB sheathing be the WRB?
