Storm Windows on old house with no insulation

[Chris Heeren]

I recently purchased an old Victorian house that has no wall insulation and single pane glass. I'm replacing all the old windows in the house with new double pane vinyl windows. I'm curious if anyone recommends adding storm windows as well to help insulate the house? Normally I would say this may be worth the extra $3K-$4K in a new house but since there is no insulation in the walls, I'm wondering if the new windows would not already have a higher R value that the walls themselves and adding storm windows wouldn't be worth the extra cost. There are 35+ windows which most of them are over 71" high, so it's no small task to add this extra protection from the winter.

BTW I live in Wisconsin where it can get below zero during the winter.

The storm windows definitely seem unnecessary if the house is not insulated as suggested. What makes you think the house is not insulated? Window is basically a sive anyway. Best triple pane windows only have an R-12. Double pane probably at R-8. Rolling out batts is a good idea if you are going to be renovating, otherwise, I would suggest blown in. If you're not going to open up the walls, insulator could come in with foam. Might be worth talking to Dwyer Spray in Beloit to get an idea of what they can do and the costs. In my opinion - money would be best spent on the following thermal improvements - insulating and stopping infiltration, improving efficiency of heating and AC - replacing windows. Hard to give advice not knowing what your plans for the house are.
