Is your home insulated (the exterior walls)?

If your outside walls are insulated and your neighbors have poor to little insulation, there really shouldn’t be an efficiency issue as far as your utility bills are concerned if they heat their homes to the same approximate temperature as your home. If the temperature on both sides of the party wall are roughly the same, you don’t lose any of your heat.

Your neighbor is losing plenty of heat (and money) if they don’t have any insulation due to the temperature difference between their homes exterior surfaces and outside. However, if they keep their heat low, or the unit is vacant, then the lack of insulation between units can be an issue. You could always insulate the party wall (depending on construction type) to prevent this and it also helps reduce noise transmission through the wall.

There are a few possible solutions for each area of your home. A few of these are:

Attic/ ceiling solutions: air sealing in combination with blown in cellulose or fiberglass insulation, fiberglass batts, or spray foam insulation to the roofline.

Wall solutions if there is no insulation: dense packed (blown in) cellulose or fiberglass insulation, or pour in place spray foam insulation.

Basement/ crawl space can be insulated with either fiberglass batts or closed cell spray foam.
