ICF performance by zones
So I am looking into ICF panels. Currently looking at Amvic systems. My concern is I live on the boarder of zone 5 & 6. It can get really cold -0 and really hot +100. There isn’t much information that I have found that explains where these ICF walls will work well and when they won’t. I have considered SIP panels as well but I think ICF walls will be cheaper and then I’ll put sip ceilings.
Can someone give me any sources to find more info? Or at least your experience in Zone 5 & 6 climates?
