Cathedral ceiling- vent or no vent
We are having a 4-season addition built (in Wisconsin) and we are planning to insulate the cathedral ceiling ourselves. Builder did not cut in a ridge vent, and used ventilated soffits to match our house. Builder’s practice is to use batt fiberglass insulation to pack all spaces, including the soffits to choke off airflow and create a “hot roof”. Will this work?? Everything I have seen suggests spray foam to seal off the space, or using baffles and cutting a ridge vent to allow air flow. Builder insists their method is good practice. I don’t have expertise other than my research. Any thoughts?
