I’m looking for some advice on the proper method to insulate attic rafters. We moved to the mid Atlantic a year and a half ago. Our home is a two story colonial with a vented walk up attic. After experiencing the seasons in our new home. We’ve come to the determination that we need to somehow condition our attic space. Due to the ceiling only being 6’3″ the entire length of the house, we realize that the space cannot be livable (lesson learned). It currently has a ridge vent and screened vents on each end of the house. There are no soffit vents. I’ve priced spray foam -$6000. We def don’t want to spend that for a space that won’t be livable. Is this even feasible? Our goal is for our storage to not experience the extremes both winter and summer bring. I’m hoping to do the work myself. I’ve found the internet to have a myriad of conclusions from not even attempting it to spending $75000 to raise the roof. Help!
