First time homeowner. My attic needs insulation replaced badly, and none of my exterior walls are insulated. I live about an hour south of the Great lakes, it gets cold. Home built in 1966.

I'm stuck in my decision. It's more expensive, but lasts longer and has higher R Value than other options, and helps create air seal and moisture barrier (closed cell).

I have had people tell me it's worth it and others tell me it's not. I don't know who to believe, and who is just trying to get me to give them my money. If it's worth it, I don't mind spending more, but if it's all just hype and isn't really worth it I don't want to waste my money.

Is it worth paying more? What should I do? 😭
