How to insulate a metal roof that does not have any roof decking?

We are building a red iron framed barn house. The house has all roof framing made out of red iron. A metal roof is being installed on the red iron frame work of the roof. The roof does not have any wood in it. All metal trusses. We are installing a metal standing seam roof on the roof and it will not have any roof decking. My question is: how to spray foam insulation on roof with out spraying directly to metal roof pannels? So when I have to remove the pannels in the future due to an unforseen reason I will not have to redo my insulation.

Tolerances and techniques for installing sheet foam below slab

Zone 4A. I will be adding 2" of 25 PSI foam below my slab, across a width of 40', enclosed on all sides by Superior Walls. Two questions:

First, how close must the flatness tolerance be between compacted crushed rock and foam?

Second, please offer suggestions & tips for achieving this tolerance. If screeding is suggested, please be specific about how to set up screeds across a distance of 40'.

I have seen several articles here and in Fine Homebuilding about installing foam on walls, but nothing very detailed about installing below a slab.

Thanks to all.

Want to add A-frame type gables (screen room) to existing plan

I have plans to build a Log home that has a 10/12 Roof in design. Want to add a Screen a gabled A frame design to back of house. One contractor says its not good idea, but I have seen MANY attached Screen rooms on the internet....they seem to attach to house by cutting back eaves and building a A frame Screen roof on top of existing roof. One internet site used a "Cricket Roof" to divert water from coming into Screen room from roof.

“Accidental dehumidification” in a renovated building raised on two courses of block

Hello to all; this is my first post here. I am in the process of renovating an old agricultural outbuilding in climate zone 6 (Northern Michigan) to be used as a heated artist’s studio/ workshop. The slab is on grade. The building has been raised onto two courses of 6” thick cement filled blocks that are above grade. The interior face of the cement blocks is becoming wet due to thermal bridging. At the corners, where the cold from outside is most concentrated inside, the blocks are the wettest (though they get wet to the touch overall).

My storage shed plans call for a poured concrete foundation.

However sloping terrain makes that impractical. My solution is to build a deck to support the shed. The shed is 7 ft X 9 ft. X 8 ft walls, gable roof, and stud walls with 1/2" OSB sheathing and finished with Hardie siding.

The deck will be six 4x6 posts, one at each corner, and one at the center of the 9 ft span Each post rests of a 10" dia. by 3 ft dp concrete footing. The deck rim joists are 2 x 8 PT, and notched and bolted to the posts. The floor joists are 2 x 8 PT at 16" o.c. The floor will be 5/4 PT decking, nailed or screwed to the joists.

Insulated concrete slab compatibility with linoleum or vinyl plank

This is my first post - hopefully it's in the right category.

Our house is ~20 years old. For the last 15 years, I've has wall-to-wall carpeting glued directly to the concrete floor in my basement. No functional problems.

I'm looking to replace the carpeting with something that is durable, stain-resistant, and long lasting. Current front-runners are Marmoleum (linoleum, so "greener") and a FloorScore-certified low-VOC vinyl plank (Karndean).

According to our plans, the concrete floor assembly is:
- unsealed 4" concrete slab (with a smooth but unsealed surface)

Mitsubishi 18,000 BTU Heat Pump Boiling/Bubbling Sound?

About one year ago I purchased a Mitsubishi 18,000 btu heat pump. It is the low ambient heating version...FE series i believe not the GE. Last winter was brutally cold (northeast pa) and never had in issue. Just last night it dropped to about 7 degrees F. For the first time I noticed a bubbling/boiling sound coming from the line set and primarily the indoor unit. Like I said earlier, I had subzero temps last winter and never heard this noise. The heat pump continued to deliver warm air and my home never got chilly. I've always heard if ain't broke don't fix/worry about it.

Water dripping from air conditioning supply vents

Hello I thought I had figured this out pretty easily the first time I noticed it.

There was a small puddle at the corner of my bed that I though might have been one of my lovely male pups leaving a present. As I was going to clean it up, I got hit with a drop from the air conditioning vent in the ceiling.

I chalked this up to my wife taking a shower in the master bath without running the fan. We tend to have higher humidity in our master bedroom because my wife prefers the door shut and rarely uses the bathroom fan during showers. I figured some warm moist air condensed.
