In regard to my new built garage with 2X4 walls.
Can I use that ½" pink Foamular insulation on the INSIDE of my walls if
it's covered with sheetrock? I see it's for use on exterior walls, usually
on the outside but how about the inside. Seems I could add some more R
value, plus it would be a vapor barrier. (You'd think you would NOT want a
vapor barrier on the outside of the wall)
A guy down the block has some. Really bargain priced. Hate to pass it up if
I can use it.
In a garage putting the vapor barrier inside or outside is perhaps moot
since the temperature will be about the same on either side of the wall.
In a heated house the temperature inside is warmer so (absent a
humidifier) the exterior humidity or water vapor partial pressure will
be higher than that of the interior thus forcing moisture in.
There was a very interesting article several years ago in Fine Home
Building showing the extreme damage that can be done by improperly
placed vapor barriers. If you can find it and read it it would be
useful to you.
