Rain Screen: Horizontal furring strips with corrugated metal siding installed vertically

I am installing corrugated metal siding vertically over 1" Roxul Comfort Board exterior insulation, thereby necessitating a horizontal furring strip that can bear the weight of the siding. We originally furred the windows out by 2 3/4" with the idea that we would use 1 x something vertical furring strips to allow drainage, then 1 x something horizontal furring strips for the metal.

Siding & insulation

I just bought a"distressed" property. Goal #1 is to keep the renovations as cheap as possible. Goal # 2 is to be as green as possible. I am planning to wrap the exterior with 2" of 2nd hand polyiso (which I have piled in the living room.) It is felt-faced rather than foil-faced. Does anyone know anything about that? Question #2: I'm concerned about getting moisture in the walls. There's no interior moisture barrier and I'm not planning to rip out the interior walls (except where I need to put in new plumbing, wiring & windows, which is quite a bit).

Thermal bridging at overhangs

I have seen this question asked, but never answered.
We are designing a house in climate zone 4A, North Carolina mountain area, and need at least 3 feet of roof overhang. This is necessary to keep the summer rains off the open windows, and to provide shading. The roof will be an unvented shed type, ceiling at the bottom of the rafters, about 4/12 pitch, with exterior foam board wrapping the whole house.

Ductless Mini Split Heat Pump - Mitsubishi 9000 BTU vs Daikin 12000 BTU vs York 12000 BTU

We received multiple quotes to get a ductless mini split installed, and wanted to know what everyone thought was the best option. We live in Seattle, where the weather is mostly mild except for a few days in the summer/winter. House is small at only 740 sq ft, and mostly open. We'll also have our electric furnace in the case we need a backup and possibly put in wall heaters in the bedrooms. These are in the order of highest quote to lowest quote with a difference of about $900 (Installed) from Option 1 to Option 4.

Option 1: Daikin 12000 BTU 23 SEER

Ductless mini split sizing advice - Mitsubishi specific

We are going to have a Mitsubishi heat pump installed in our house (in progress) soon and would be interested in some thoughts on sizing.

The house is in Jackson, NH 03846 (climate zone 6a). It's cold and snowy, but we have great passive solar gain, open floor plan, tight construction, and high insulation values. We have wiring in place for regular electric resistance backup. Our Energy Star rater calculated our heat load at 11.2kBTU / hr at design temp (-6F, 65F inside, based on St Johnsbury VT).

Looking at the new Mitsubishi FH line, MSZ/MUZ units:

Jeff Wager has completed his Passivhaus documentary

Documentary filmmaker Jeff Wager has completed his Passivhaus documentary. When it was being edited, the film had a working title of "Balancing Act." However, the completed film has been titled "Superhouse."

The film includes interviews with many experts who are probably familiar to GBA readers, including Chris Benedict, Wolfgang Feist, Henry Gifford, Robert Hastings, Martin Holladay, Mike Kernagis, Katrin Klingenberg, Ken Levenson, Bill McKibben, Chet Pasho, Peter Schneider, Barry Stephens, Stephen Thwaites, Michael Welch, Alex Wilson, and Li Ling Young.

Multi-head low-temperature minisplit?

Has anyone seen a extra low temp multi head mini split offered. I got quoted a Fujitsu 12RLSH but was told that the extra low temp heating models, supposedly still offering heat to -15F, was only offered as a single condenser and air handler.
I am building a three bedroom ranch in Northern NY, my heat loss is around 21,000 BTU/hr.
The floor plan is mostly open but the bedrooms are on opposite sides of the house and might have doors closed.
I will have backup electric baseboard but would like to have cooling in the rooms so I was looking into a multi head system.

Q&A map should show climate zones in Canada

Please add a Canadian map in the Q&A section header.

[Editor's note: Here is a link: Climate Zone Map Including Canada.]

i believe that there are enough Canadian users/members to which it would be useful.

i also look at the USA map often when reading stuff from US members to understand
their situation. Probably reverse happens also.

Show some respect! ( always wanted to type that ..ahhaahah )

Neway you guys down will probably want to know in which zone is the Stanley cup residing this year, next year and so on ... :p
