Thank you Josh for great advice to prevent mold. I would add one more thing that is really important to prevent moist from coming in. It is becoming increasingly popular with in-floor heating. It is really nice and also an over time economical way of heating your house. One problem that many do is that they only insulate the ground under the concrete slab to the values of their climate zones. These recomendations is for the zone itself only. Now, if you have in-floor radiant heating one must insulate much more. The reasons are that 1, you dont want half of your heating to also radiate downwards, you loose effeciency in that. but also, 2. radiant floor heating that is not well insulated to the ground will basically suck up moiste from the ground below. Looking at how they do in countries where in-floor radiant heating have been common for the last 40 years, like Sweden, a minimum of 250mm, or about 10" is needed but many will go about a foot deep under the slap. Now, the walls need to be even deeper to prevent the chimney effect.

Thats a very interesting point I had not heard. In Texas the radiant floor heating is not as common but that does make sense that it will cause the moisture for good soil to dry up more and cause expansion potentially as well. Thanks for your comment! JH

An hrv in my attic solved the condensation problem on the steel in the winter. Keeps the heat in, but exchanges the humid air with dry air

Thank you for all these tips. I live in Mesquite New Mexico just outside of El Paso Texas. We hardly get any rain and we are building a 50 x 80 barndominium. Do you have any advice for us?

Very good advice. Now I know that when I spend a few weeks in the mountains during the summer days to cool off, it would be a bad idea to switch off AC because it increases the humidity. Thank you 👍

that is correct. needs to maintain

Thank you!

Your advice is spot on and well explained! I am considering a barndo in humid North Florida for a new home and I am concerned about spray-foam on the underside of the metal roofing limiting thermal movement of the roof and eventually de-laminating in spots. Have you tried other insulation/vapor barriers such as Prodex or Smartshield in combination with "bagged" fiberglass or rockwool? Do the benefits of spray-foam outweigh the possible drawbacks? I have run a portable dehumidifier in my South Florida house in winter (when AC isn't running much) for 30+ years and the new ones work really well at controlling humidity especially if you can drain them through the hose.

I wish all builders understood this information, because they are doing an injustice to customers when they short them on the insulation and ventilation needs.

You obviously know your Sh…tuf, if you are talking about variable speed HVAC equipment. FWIW, it might have been helpful to explain how slowly drawing air across a cold coil will wring the moisture out of the air. Good stuff TBC!

How do you keep the cement from cracking in a one level? We would like to put in tubes in the floor for ground source heat system.

Are barndos flammable?

Do you build in Colorado?

I worry about the spray foam on the sheetmetal roof and roof leaks. Dispel them please Josh.
