Insulating Metal Siding

[toy]

Piloon the insulation in the bag type I have seen that used in metal buildings, and I figured that if that was how the commercial people did it an adaption of it should work for the home owner diy project. That is how I did my metal building on the sides plus I stapled the sides of the sides shut over the studs. When I did this I also reinforced the entire building and if I have problems in the future I am going to replace the sides with chip board and then vinyl siding. When I do that if I have to [ hope not ] I will take out the double vapor barrier.

If U do replace siding U could always perforate the outer barrier to let it 'breathe', but I would actually think it not to be necessary as long as the insulation remains dry.

The main factor is to have humidity stay on the warm side where the warmer air will evaporate it.
Evaporation cannot occur inside of wool.
The breathable outer house wraps are to prevent water from entering and allow any that does a way of escaping
