Trusses and ceiling insulation and air infiltration elimination
Hello. We are building a new home at this time, and I am trying to maintain a Passive Haus standard. We are using ICF walls which will be easy to ensure an appropriate R-Value and infiltration value, but we are also using trusses. I would like to use cellulose totaling to about R-60 or more in the ceiling. I just am not sure of the best way to seal the truss overhang and ensure close to zero air infiltration in this situation. Please advise on good techniques on sealing the trusses.
