Is R-1 fan-fold insulation cost-effective as vinyl siding …

Using Fanfold Insulation Bundles - GreenBuildingAdvisor
2022年6月5日 · That fanfold stuff is usually XPS, not EPS, but that's not a big deal here. It's probably the 1/4"(ish) thick stuff rated R1, so it's not going to do much BUT it's hard to argue with free!

Tyvek and / or fanfold insulation under siding

Can Exterior Foam Insulation Cause Mold and Moisture Problems?
2010年6月23日 · 2. You can increase the R-value of your R-5 sheathing to R-7.5 by adding a 1/2-inch layer of XPS. No, 1/4-inch fanfold isn't thick enough. 3. What should you do? That's up to you. I don't know what your budget is, or your appetite for risk. If you can afford to do the work, I would certainly recommend beefing up the thickness of your exterior foam.
Does the housewrap go over or under the rigid Foam insulation …

Anyway, we want to install 2" rigid insulation on the outside of the log walls and use stone veneer. I am trying to understand the wall section though. My thought is: …
