exterior finish on 1850s farmhouse

I've got an 1850s farm house I'm in the process of renovating. The house needs considerable exterior painting.

Do you all have recommendations on the best exterior finishes for an old house like this? I could shingle instead of painting, for example, or strip and stain.

I'm hoping to create the most energy efficient old house possible with minimal future upkeep. Paint seems to need redoing quite frequently, and other possibilities would be welcome.

Thanks,

Ilmari

Perlite for walls vs Dense pack Cellulose

Hello-
Has anyone used loose fill perlite for wall cavity insulation on wood framed exterior wall. I am interested in the least toxic insulation for the walls. But I am a little concerned about the moisture retention capabilities of perlite. Does the perlite dry out quickly in a normal framed wall?

Also, does dense pack cellulose have less capacity for moisture retention?

Lastly, has anyone used loose fill perlite for attic insulation.

Pond pebbles instead of crushed gravel for the driveway - what to do??

Hello,
Our general contractor received a wrong kind of gravel for our big driveway install. We have 1500 sf to build and 1/2 of it is a concrete driveway and 1/2 permeable pavers. We have 2/3 of the total rock needed already on site. And that rock is pond pebble instead of limestone gravel that would have properly compacted under the driveway. Supposedly this cannot be returned. What are we to do?

Best furring strip over exterior foam to hold Hardie siding?

Ok, this has come up before and I want to get final recommendations from those who have done the work in the field as my foam board is almost finished.

I have attached 2.5" of recycled EPS to the exterior over my drain wrap. Windows are INNIES and are flashed well. As a point of fact, the Tyvek brand tape worked and adheres excellent to the EPS. I have some 3M all weather tape but the Tyvek tape works great and is easier to work with.

roofing and insulation on old house

I have an 1850s farmhouse I'm renovating. To insure good insulation, I had the attic rafters spray foamed with closed cell foam about four inches deep.

I'm trying to plan for an eventual re-roofing, and I wanted to know if there are any best practices I should keep in mind at that stage for eleminating any issues that might arise from the spray foaming. The old roof has a few layers of shingles on it.

Is there a recommended roofing type for this situation? Any ventilation issues I can helpfully prevent moving forward?

Thanks,

Ilmari

High humidity in spray foam attic

Hello all,

Last fall I had my attic spray foamed. Warm temperatures have arrived and I am experiencing higher than anticipated temperatures and humidity in my attic.

I have 3 main questions (pertinent details follow):

1. Is a semi-conditioned attic RH in the 60 - 70% range cause for concern?
2. Should my attic be 10+ degrees warmer than the interior? It will get much warmer here in the coming months and I am worried that the attic temperature difference will grow.

Insulating floor of mudroom before closing it off

I'm building 5' by 8' mudroom addition where there previously had been a dilapidated porch-like structure. I've poured the foundation and secured the sill. The concrete foundation is about 5 inches above soil, then 6 x 6 sill. I will be framing the floor with 2x 6. I'm stuck with these dimensions because of grade etc. This "crawl space" is NOT connected the the main house's crawl space and will be 100% inaccessible once the subfloor goes down. Also, foundation is non vented.
Anyway- the plan is to-
