monolitic slab

[user.69169]

asinine concept to put insulation in a perimeter location either way. If not up against a solid surface like a basement, it is both worthless and I wouldn't do in this situation. It will be what is heaved.

Here assaten fer ya. Frost starts on top of ground moves across top of ground den goes down. You got dirt tight up to slab. WHAT stops cold goin into side of slab from dirt if you not frost fence?

You want 11? Heat rises. How ground under slab get cold to start? Gotta come from outside after goes down.

Object de game is to make slab thermal battery.

Not really...Hot air rises but heat moves from hot to cold...

You know Slushi I really like to help you wid understandin BTU in motion, and thermal battery along wid heat transfer betwixt different materials, but you not up to de task.

Probably best you run along back to peein on yer sock an sniffin to see if you makin de turpentine.

How do you say idiot in your pidgin?

You said "heat rises"...it doesn't, get over it...your analysis may be spot on but your statement is utterly false...
LoL...Heat transfer is hardly brain surgery or rocket science...:laughing:... It's those basic theories that you learn early that stick with you...and heat still moves from hot to cold (at least on this planet) all day and all night...one more time so maybe you'll get it...Hot air rises...Heat moves from hot to cold...! you should do one of your google searches to learn about heat sinks etc...! :laughing:

BTW, FYI I'm a profound student of the laws of thermodynamics...!

/pine is correct. Heat moves in any direction due to thermodynamic principles and hot air rises because of a change in density. You can have one without the other; they are entirely diffferent mechanisms.

I deal with building departments all the time with my day job. Some inspectors only know what's on paper and only allow what's written by the lawyers who must have been paid by the word. Ideally you would have put insulation under the slab, because as /Pine stated, the cold ground will pull the heat out of the slab. Now if you can furr up the floor with joists and insulate between, that's different, unless you will only have living space on the second floor? Also keep in mind, bedrooms and habitable spaces need proper egress, not to mention smoke detectors, and if above the garage, CO2 detectors. Know any engineers that might prepare a letter to the building Dept to state that it's of solid construction and adequate? Sometimes inspectors just want their hind quarters covered, don't want to be at fault should it fail, then it's on them.

Yes I wish I would have put rigid foam underneath but I did not. To the bottom of the floor joists supporting the second story from the concrete floor is a bit over 10 feet. I guess I could place EPS foam on the floor (they have some that support 40 or 60 psi. I could pour concrete over that or put wooden floor joist in and add the rigid foam between the joists. Kind of like tall sleepers. I have two standard entry doors but it would not be hard to remove them and change the opening. The stairwell would be a problem unless I made the new floor at finish the same height as the first step. It would be even with it and effectively gone but then all the steps would be of uniform height. It is a steel stairway.
I am really open to all suggestions. Will have to see what they require. Maybe rafters on the floor may be the way to go. The floor would then be insulated. Maybe some room for duct work or lines depending on which was the rafters would be ran. If so if one isolated the joists with a moisture barrier could FPS wood be used or treated.
I like this site. A lot of minds with ideas and experience.

You real sure you want to lock dat position in Slushy? I give you time to think on it.

In 21st Century Cajun we say "Thall303" fer de word idiot.
Thanks fer askin rather den jumpin off on stupid path.
Always glad to help language impared folks.
