Caulk gaps in timber frame?
We recently bought a 25 year old timber frame. Some timber members have gaps between them up to a 1/4″ enabling me to see the 1 inch blue rigid foam insulation on the outside. We’re in climate zone 6 and I can feel slight air movement near these gaps. Is there anything wrong with sealing them with caulk? Does is increase risk of rotting the timbers?
