You could side it, but I wouldn’t use vinyl. Go with some sort of cement board or Hardy Plank. As for preparation you should check with local building codes or a local lumber yard.

I would not recommend covering the logs until the rotten ones are taken care off. It will continue to rot and could become a structural issue in time. Call Ryan at 877-788-5647 for help with that. I do not know of any vinyl covering.

You should put the tyvek on then fir strip. You will have a natural air space behind the fir stripping. Caulk from top to bottom with Energy Seal caulk. Do not fill with foam.

Fir strip it (strap) and caulk with Energy Seal from top to bottom.

I really don’t know the answer to this other than I do not think it is any greater a fire hazard than regular wood siding.

Too many variables to say for sure. A local contractor could answer better.

Do not know. Who ever sells it should be able to tell you the pound per lineal foot.

Call Dave at Timeless Wood Care Products for directions and product at 800-564-2987.

I do not know of any right off. Try Google for log siding in VA.

Yes either chink or caulk. If the gaps are 3/4” or less use Energy Seal. If larger use Perma Chink. Call Dave at 800-564-2987 for help and the materials you will need.
