Venting: Roof ridge and gable ends without soffit venting

We are doing a vented roof with access to the attic space through the East Gable End.
The Roof Ridge will be vented.Instead of the soffits to provide air floor to roof ridge use the gable ends to provide air into attic space.

General info
20 feet x 35 feet length to gable ends. 700 square foot home
7/12 pitch simple gable roof
12 inch raised heel roof
Synthetic roof under lament
Low Heat coated Metal roof
The gable ends face east and west
Area in which we live in receives good south west wind most of the year.

So the question do I need soffit venting?

Inadvertant trap in mini-split line set?

I'm finishing the installation of my mini split line sets and realized I may have introduce a "trap" into the line set due to the way I had to route it.

The main line set runs from the compressor to the branch box in the attic. From the branch box, the line sets run down into one stud bay, in a 180 degree bend, through a stud, and pointing back up into another stud bay. This 180 degree bend is my concern.

How do I prepare for a blower door test in new construction?

I'm interested in doing a blower door test on my new construction house.

I have read some of the articles on here about blower door testing, and most appear to focus on existing construction.

One article said to preform the test on new construction after insulation, but before drywall.

In the typical insulation / drywall progression, wouldn't the walls be insulated, then everything drywalled (including the ceiling), and then ceiling insulation laid on top of the ceiling drywall?

Can I put rigid foam insulation over plaster exterior walls of a brick house?

I live in central Illinois and it gets very hot or cold during summer and winters here. My bungalow was built before 1900 so there's literally no insulation in the house except for the attic. I was thinking of putting up some the pink R-10 rigid foam board insulation on my walls and then drywall over them. the walls currently have layer of lath, then plaster, then thin wooden paneling over the plaster. Is it ok to attach the foam boards over the wall without tearing anything down? I don't mind extending the windows and doors or refitting the electrical outlets. Thanks.

I’m at the plumbing stage for my tiny house on wheels. After hiring a plumber, I see that he has an aav vent for both the kitchen sink and bathroom sink, in between the wall studs.

1) Considering that I am not hooking up to sewage (composting toilet), do I even need a vent?

Retrofit of a cathedral ceiling

I am living in a Log Home in Madison WI. (Zone 5-6) with a vaulted Ceiling. (2x6 rafters R-19) I am hoping to redo the roof soon. I wanted to put on a layer or two of Rigid Foam. XPS or EPS. Ideally getting close to R-20 plus the 2x6 insulated cavity. I will then put a standing metal seam roof on top of the foam using furring strips.

My issues are this. I am concerned that I will be trapping moisture between the XPS or EPS and the Vapor retarder or Vapor Barrier that is most likely installed on the warm side of the house. Right behind the sheetrock and before the batt insulation.

Wi-fi app to control minisplit systems


there have been a few different ways of achieving wifi / app / remote control of mini split systems, most all proprietary and quite expensive.

I came across one I haven't seen / thought of.and couldnt find here on a search

instead of directly controlling the mini-split via wifi, this method is to directly control a third party IR transmitter, in line of sight of the mini split, by wifi/app.

the IR transmitter then communicates with the IR mini split receiver

So the app will then duplicate all the remote control's buttons.

Triple-pane windows for a high-efficiency cabin

1400sq. Ft. cabin...Zone 7 10,000 HDD with R40 walls and R80 in roof. Looking for ideas for windows. I'm probably looking at a manufacturer in North America for costs and timeline to get.
Have looked at H-Windows, in person and several others online, including Marvin "Tripane".

Any pluses or minuses with any of them would be helpful.
