Suggestions for insulating a large garage workshop

Hi everyone. I just purchased a property in western Massachusetts zone five a. I am planning to renovate the existing 24 x 60 barn for use as a year-round workshop. The building is slab on grade with 2 x 6 framed walls 24 inches on center, sided with rough pine board and batten nailed to the studs and bracing. Currently, there is a bit of air exchange between the interior and exterior due to some of the battens pulling away from the nailers.

Best way to insulate an old attic?

I am the owner of a 100-year-old two-story house in the 5A climate zone. The house has a full-height attic space, which is currently uninsulated. The attic has actual floor boards in place over the joists, which could be removed, but would be a lot of work. Right now we just use the space as storage, and don't plan to convert it to living space. During the winter i run into huge icicle and ice dam issues. My question is, would it be beneficial to me to insulate the parts of the roof that are accessible(id say 70% is not covered)?

Rigid foam over WRB

I am finishing up a full kitchen remodel that pretty much required me to rebuild 25' of exterior wall in my 1600 s.f. 1950s ranch located in Portland, Oregon (zone 4 marine). It is a 2x4 wall with R-15 fiberglass, existing 1x8 shiplap board sheathing (less some areas with wood damage, yes we do have termites in the NW), window and door rough openings flashed to a Tyvek primary WRB and air barrier. I would like to add 1-1/2" of rigid foam with taped seams and a 1/2" rainscreen before replacing my cladding.

Retrofit an existing exterior wall to 1-hour rating

I have a small garage conversion project that is within the side and rear yard setbacks and requires one-hour rated walls, eaves for approval. Any thoughts and solutions that balance compliance and a small budget (i.e. demo and rebuild, exterior versus interior modification). USG wall assemblies suggest 1/2" Ply and then exterior wall board (but the garage is now sided with lap siding).

Thank you

Locating flue hole without removing wall paneling

I am trying to install a wood stove in a room that has paneling on the walls. The chimney flue has been covered by the paneling. I'd rather not remove the paneling because it was glued to the wall when installed. I have tried several ways to do this but was not successful. I dropped a measuring tape down the chimney, took a measurement but was way too low for the flue when I laid the measurement out. Check the room next to this room and found the chimney and a sealed flue on the opposite side of the chimney. Thought about knocking out the plaster or concrete seal, still an option though.

Mixed-humid insulation recommendations

I've read a great deal about building science and energy-efficient building practices. This site is a great resource. I think I understand the theory, but I have a few questions that are perhaps best answered by experience.

Air sealing and insulation question

I am buying a 1900 bungalow in the white mountains of NH, 10 foot ceilings 4 inch walls. The only insulation now is the attic is capped. The heating is hot air, with unsealed or insulated duct work. The house is one story. We are closing in October, so I'll have no access until then. Where should I start?

Make up air for clothes dryer; exhaust only system

In new construction with an exhaust only ventilation system, is there a need for a make up air source for an electric clothes dryer. I am toying with the idea of some supplemental passive air sources...

My wife needs convincing ...

You all have me convinced that I can change out my Mitsu AC minisplits with some all season heating and AC cold climate heat pumps and save substantially on the energy costs over my 98% efficient boiler.

But my wife is not convinced.
