I need to add more insulation in the attic crawl space in my attic. Presently I have about 4 inches of rolled faced pink insulation. I was going to blow in another 20 or so inches of cellulose. On the 2 gable ends of the attic I have ventilation louvers. Since this is a Gambrel I do not have soffit vents. What do i need to do to improve ventilation? Are the vents in the gables good enough?
Thank you
