Gable vents are easy to do. Some can be powered as well. If you have a roof/attic design that will lend itself to gable vents I would go that route.
How are you sure that there is enough Soffit Intake Ventilation?Thanks for the reply... that makes sense. There should be enough air from the soffit, but I'll check and make sure there aren't any blockages.
So, is it possible to add too much ventilation? I assume at some point there are diminishing returns....
Would a radiant barrier be any help? How does it get applied with the existing blown insulation?
