Northern Michigan un vented, un air conditioned Cabin roof design.

Northern Michigan un vented, un air conditioned Cabin roof design.
After reading several articles, opinions and Blogs I have a better understanding of the moisture vapors that exist and the problems they can create in walls and especially the roof. But I’m a little unsure of the proper design and construction for my great lakes, shore line cabin roof design. I have detailed my current plan below. Could please you give input as to where my design plan is OK or deficient in proper vapor management for this environment and situation.

What to do with torrents off the roof?

Zone 4A, East TN, annual rainfall >50" and downpours can be significant. Upslope lot.

Downspouts will tie into 4" pipe to daylight, but then what? Seems responsible to NOT discharge it down the driveway. But if I discharge it onto the slope it would soon create a local grand canyon.

There will be a 3' garden wall to provide a level grade in front of the house. The 4"gutter drains will exit through that wall in two or three places.

Any tried and true remedies?

Insulation retrofit

Looking for some advice on a smallish rehab project I am about to start. I've read many of the great articles and Q&A discussions here, so I think have bit of direction...but as I am novice, I am interested in some feedback before I moved forward.

Insulation for vaulted ceiling

We re-roofed our house this summer and found a lot of damage over our family room with a vaulted ceiling. We replaced the plywood and are now redoing the underside. The roof has a roof ridge vent and ventilation holes in the soffits. We are creating on-site baffles with 1" rigid foam boards. We are planning to use R30C insulation which is denser for cathedral ceilings. The question is do we use faced or unfaced, and do we need to use plastic sheeting as a vapor barrier? We want to get it right this time!
Thanks,
Kim

Mitsubishi minisplit 8-head system is not keeping up

Back in mid-November 2016, we had a Mitsubishi Hyper Heat MINI Split installed in our house after opening up the first floor of our home and installing some beams to make it more open. We lost duct work feeding the second floor, and had to come up with a solution. We decided on a Mitsubishi ductless system, since I had a smaller version installed in our detached garage and was very happy with it. My uncle did the garage, while I went with one of the Mitsubishi Diamond Dealers to handle our house. After 3 quotes, we decided on a company and proceeded.

Intus Eforte mounting brackets

Question for anyone with experience installing Intus Eforte windows: The brackets I received with my Intus windows seem too wide. There should be a pic attached showing a bracket sitting in front of the track it is supposed to twist into. Online images depict a different type of bracket. All mounting instructions depict brackets with teeth that are only slightly wider than the mounting track. Did I get a batch that belongs with a different window type or something?

Thanks for any help.

Vapor barrier inside double stud wall — is this OK?

I’m building an energy efficient house this spring 25 miles Northwest of Minneapolis in the upper portion of zone 6. My wall design plan since the ’80s has been a double 2x4 stud with the vapor/air barrier in the gap between the two walls. This is similar to Joe Lstiburek's Ideal Double-Stud Wall Design with 2 taped layers of 1.5” Foil Faced Polyisocyanurate foam board replacing the ½” OSB in Joe’s design. I believe this design would keep the inside polyiso vapor barrier well above dew point under the most demanding winter conditions.

Insulating a block building from the inside

I have read all i could find on insulating a block building. It seems the best method would be to add foam to the outside. Unfortunately this is not in the budget for this project. The only mention of interior insulation seemed to be adding spray foam. The main building for this project is a two story from the 1930s with two later single story additions. Currently the inside has been completely gutted, while we hope to keep the outside intact.
