Addition insulation

We've bought a 1939 house - very good brick construction, thick walls, everybody complements it. There is a newer addition however - build probably in 1984-85 as written on the carepet that we removed from there. Unfortunately there is palpable difference between the quality of two structures... We installed new hardwood floor - exsactly matched to the 70 y/o one that the rest of the house has and crown moldings.
The only problem now - remarcable difference in temperature like in the previous post.
We beleive it is a lousy insulation - we measured temperature on the surfece of the walls - it is different.
My question is - can our addition be insulated from outside - we would like to strip off vynil siding, apply insulation and cover it again. Can this be done? Any advice?
Thanks

Yes --- absolutely.
It's done quite often with rigid foam and is very effective in providing a continious thermal break. If you decide to change the siding to stucco, foam is used for the substrate with the stucco applied over top.

Hopefully this helps.:)

Re: Addition insulation

Thank you Canuk.
How many Rs can it add?
A general contructor told us once that it would be impossible to do it from outside - only from inside due to woterproof barrier issue or something...? We suspected it is not true as we saw other houses doing insulation from outside. We did not enquire an insulation professional yet as we are doing inside reno which hopfully ends soon and this will be the next project...
Is there any advantage in using stucco over other materials? I saw in a store - there are stucco sheets. Is this the same? Is it expensive? We also have a detached garage covered with the same vynil - will probably need to be covered with the same stucco?
