I looked on a site- maybe DIY.com, and they had several articles on replacing windows. A couple of articles made the claim that in most cases replacing a single pane window with a modern double pane is a waste unless it's just for looks. They said that attic insulation and a few other things went much further, and that replacing windows was sort of a fad as of late. Now I have leaky poor fitting windows- so I really need new ones. They don't lock all the way and I can feel a draft out of them. So my question is- do people focus on the wrong things in energy savings? Are we penny wise and pound foolish? Should most new woodstove buyers looking to save on heating be doing something simpler and more basic first- like insulating attics?
