What’s more heat efficient, insulating walls or replacing old weighted double hung windows?

Question

I just recently baught a house that was built in 1935 and the walls are not insilated. The windows are old i think they are orginal to the house and have counter weights on them. They are wooden and double hung. Also the attic is insulated.

Answer 1

Would you believe I just got back to Fla. from Mich. Worked on a house that was probably kin to yours. Hope yours is in better shape!!! I agree with the masses. But when you do decide to replace the windows don`t forget to insulate the sash weight cavities. Also the easiest way to insulate is blown, but keep in mind in 1935 it was very common for carpenters to install random pieces of 2X`s horizontally between studs that will prevent your insulation from totally filling any given cavity. You may consider stripping the interior and insulating with glas or foam, then redrywalling. Also a good time to update wiring. GOOD LUCK!!!!!

Answer 2

insulating the walls is the most efficient thing at this point also a nice piece of plastic over the window will help keep the drafts through winter. i would change the windows after i insulated the walls but windows are expensive for the good ones.

Answer 3

The insulation will probably be less costly to install now and will get you through this winter but in the long run, the windows will save you on heating and cooling costs so I would budget to change out the windows at some point in the foreseeable future.

Answer 4

Insulate the walls - I had the same problem!!!! I can see grass growing up between the window sill, and the siding, but its warm! Windows coming in spring!
