Best air sealing and insulation for knee walls in tray ceiling
I have a single family home in climate zone 5B.The attic is ventilated. I had the attic air sealed and insulated to R50 with blown in cellulose 1 year ago. It looks like they neglected to do the knee walls properly on the great room which has a tray ceiling which is 3 feet high (see photo). They just wrapped the knee walls with batt insulation and otherwise didn’t do anything else.
1. What would be the best options to air seal and insulate the knee walls?
2. Is this difficult to do since the attic now looks like a winter wonderland?
