I live in Minnesota too n 20 years ago I put 1/2” o c pink foam on the inside before I put wall board on. FYI call the u of Mn n they say insulation holds the heat in and in ur case keep the cold out. The siding was done so I had to go inside but I tell u my only regret was not going thicker. Warm walls. Now the windows r the cold spots. We need the r-11 window like the outfit in Colorado sells.

Thanks Matt.

How long b 4 that shrinks from the heat an creates gaps, ive seen what happens when its Exposed after a couple years with no protection from the elements an i read that Extruded foam loses r value over years

Greg, Thanks for the question. Actually this insulation was covered up a few weeks later by the cladding that went on the home. You are correct, in that, foam insulations are not UV stable and need protection from the sun. Also, I would like to point out that there are many types of continuous insulations, raging from mineral wool to spray foam. In terms of long term R-value loss, yes the windows we buy, and any product that uses trapped gas to achieve higher R-value, may lose part or all of that gas over an extended period of time. In all honesty though, that would simply make it the same R-value as those insulations or products that trap air for their R-value. The real key to continuous insulation is that the thermal energy transfer is being reduced before it gets to the framing of the wall, regardless of the insulation material you choose to do it with.

The tape will fail...sorry.

0:30 this analogy makes no sense would you take the insulation off your house?

Making homes too expensive when we have a shortage? Great.
