Permeable Waterproofing for foundation & impermeable for roof? – GreenBuildingAdvisor

I was wondering if anyone had a good recommendation for a liquid applied water proof memberaine for a foundation exterior? It’s a new build and insulation followed by Delta-MS would go over it. I was thinking there was a product like LWM200 or something but I can’t find the name now.

Also, my understanding for a vented roof, where the attic is insulated well, but the roof itself is not insulated (no insulation over the plywood sheathing), it is best to go with a non-permeable membrane underneath a metal roof to prevent condensation and moisture issues. Is that right? Does anyone have a good recommendation for this?

Thank you!
