Can you help me explain to my husband
1) WHY you stipulation vapour row to be as sealed as possible
2) Why you can't put wood against a concrete foundation near nothing within (and why the government isn't of late "stupid" for making that code).
3) Why even with asphalt paper on the concrete you still inevitability vapour wall.
I get it, but I can't capture him to understand it!
Thanks.
(if you DON'T live somewhere that have very cold and totally hot times then spray barrier is used contained by different ways or not at all.)
Answers: Why= Because near the change within temperature it creates moisture The vapor screen keeps the moisture out side of the structure preventing sea from rotting.
Wood= Most codes I'm sure want pressure treated material for plates (which is the 2x fabric on the slab). Hopefully your walls are six inches and not four.
A vapor barrier can also increase the r helpfulness of the insulation.
Good Luck

Because a slab foundation is not just one solid piece of concrete but plentiful slabs of concrete with two-3 inches between them allowing for movement and shifting of the foundation as the ground moves with loss of and adding together of moisture. With the loss of moisture, the floors will shrink and pull away from the slab whether you use that worthless moisture weir glue or not. With the accumulation of moisture outside, you will get moisture seep up between the cracks causeing the wood flooring to expand and heave up coming loose from the concrete and creating a integral other issue. Whatever you do, make sure that you sign out about 1/2 inch undo edging around the room to allow for the natural expansion inside your home in recent times from humidity and from your home shifting. If your floor separates from the glue later you will have to buy different wood flooring. The best alternative is to put down the moisture barrier and afterwards either epoxy resin it down or allow it to be a floating floor.
While I was not aware that the political affairs actually have a code saying you HAVE to put down a moisture boom on a slab foundation, I could certainly see why because here would be so many folks sueing the idiot installers for making them buy more wood flooring to replace flooring that got ruined due to a scarcity of a moisture barrier to switch on with.
