The current siding consists of asbestos shingles over original clapboards. I have removed a few with just a long armed transfer shovel. I was curious to see what was under them. Yes I will dress properly to remove the rest ;-)
Questions: 1) Once the shingles are removed, can I put some sort of foam board over the clapboards and then wrap? Will that be airtight "enough"? 2) I then install vertical furring then install the vertical metal siding. Is that going to work?
What I want to prevent is having to remove the clapboards. But I will and then sheath in zip if need be if that's the best option.
I want to save money...
