We just finished a small cabin to lockup. We used IFC for crawl space. Do we need to heat the crawl space over the winter?
If you have pipes etc., that will be damaged if they freeze, you need to heat the crawl space. You should shoot for 10C as this will protect you for an additional day or 2 if the power goes out. The other way to do it is to winterize by draining everything and then using a biodegradable plumbing antifreeze in all of the traps. This Wil protect the pipes from freeze damage.
Good luck with it.
