You need to determine if the exterior wall has existing insulation to answer the question... This can sometimes be determined by pulling off a exterior wall electrial plate and visually look at any gap between the the electrical box and drywall to see if any insulation is noted. Drill a small hole in an exterior closet wall.

If the exterior walls are 2 x 4 framing with no insulation- either foam or dense packed cellulose. An exterior brick wall will require filling the wall cavity from the inside with 2 holes every 16" inches. Get a good insulation contractor.

Since you live in an area with real winters, if your house does not have a vapor barrier under the drywall, you could have real mold and rot issues if you use cellulose insulation, so in that event I would recommend foam in place insulation.

You should be able to see if you have plastic sheeting vapor barrier right under the drywall by pulling a few outlet covers or maybe a piece of window trim on an exterior wall. Without that, moisture penetrating the walls is likely to wet the insulation, causing insulation sagging in the cavities and mold and mildew growth, and in areas of significant air leakage likek uninsulated outlets and pipe penetrations, actual water and ice buildup potentially leading to rot in the wall structure. This is likely to be even more aggravated in homes with brick facing, as it conducts heat away from the walls better.

It is impossible to recommend insulation type without know more about what you have in terms of vapor control, sheathing, current insulation, etc.


Depending on how the exterior sheathing is set up, your current insulation, interior paint layers and type, and exterior cladding, you can use cellulose.


You need to post up a bunch more information to get a proper recommendation and to even get more information as to the nature of the inquiry.


At minumum, deal with an insulation contractor that knows his/her craft as changing insulation and vapor control layers in a home can have disasterous consequences.

Unless you have had it done already, air sealing and insulation is a must to start with.
