My attic insulation is probably 50 years old, crumbling away. A few questions:
1) I am looking to blow insulation in and am getting conflicting information about baffles. I have no eaves on any of the roof lines, instead gable vents on each end of the attic, a mushroom fan with a thermostat, and an attic fan (that we never use but has louvers). I am assuming this means there is no need for baffles since there is no air flow from where the walls meet the attic. Is this true?
2) do i need to box out all of the fixtures (high hats, electrical connections) and avoid them with the insulation?
Thanks in advance
