Cellulose blown in insulation degradation
I’ve read where cellulose insulation can degrade much faster as compared to other types of insulation. As early as 15 years and has a life span of 20-30 years. Yet most folks seem to recommend it over fiberglass. I can not get mineral wool in my area. My concern is that I plan on insulating a vaulted/cathedral ceiling, so unlike an attic, there won’t be an opportunity to add insulation years down the road.
