I think I would like to have insulated below the house and have conditioned space everywhere including the garage and attic.
Awesome advice ty
Working in the HVAC industry for 30 plus years, I've seen nightmares like what you're describing. Many architects and engineers don't think about these kinds of things.
Another way. Like yours.. just not a whole ceiling..
Have all mechanicals only in that lower insulated room and penetrate only directly into the house.
2nd.. would be to keep all mechanical that does enter into the garage tight, and create essentially a box. A run that could be properly sealed. Commonly done in a finished basement that has a primary duct running across a wall/ceiling, to finish the room. Often no insulation because that basement is now part of the main house package.
Make sense? I hope. Lol
Good points. One question though, why drop down the entire ceiling? Why not just box the duct in the corner?
The whole floor will have ducts and pipes running every which way.
@@SprayJones Sure, but usually only the main duct run won't fit in between the joists.
I have never seen any places where they dropped the entire ceiling. They just created a drywalled in box in the corner of the rooms (usually down the middle of the house which I am not a fan of, but it does make the duct runs shorter).
It probably makes running things super easy though.
Why was it you can't foam up to the flooring and do mechanicals below afterwards? Just order of work per the plans or other reason.
Go watch the video I did about it.
Only video I find is going direct to floor over a cold car port. So I guess it's fine then.
How would you insulate the Floor of a house on piers? I would assume it would be similar to what you mention here. I have heard in the South Coastal region (Gulf Coast), that some people don't insulate the floors. I don't think that would be a good idea, but that is something read. What are you thoughts? And would an Open Cell foam work in this area of the floor if Closed cell prices are too high? Would there be a considerable benefit to closed cell vs Open here?
2 ways. You make enough room to install plywood or something, on the underside of joists. Or you cut nailer and attach them to the bottom of joists and cut plywood to fit in-between. Then insulate.
Open cell is crap it's cheap for a reason like cellulose. If your going to do foam you might as well use closed cell unless you need to have vapor permeance, in Wich case I would use dense pack fiberglass instead
Build the structure, sheet the bottom of the trusses, spray foam and then install ducting from above and close the floor up.
Why are they not training the drafting and building people in school?
Good question - we aim to help with that.
An easy solution is to just insulate the garage walls. A built in garage should always be insulated. An attached garage it wouldnt matter
And what do you do when the door is left open? Code is to insulate it so it must be done.
I would want the garage insulated. To atleast make it more comfortable in there.
4th rule of insulation, you can't stop conduction you can only slow it down. You wouldn't leave the ceiling uninsulated but the garage walls need to be done. Why would you leave the garage door open when the garage is built in. You will always have heat transfer through the floor to the garage, r value doesn't stop heat transfer so you should always insulate the built in garage
stay warm lol later kenadian
