I think so -- won't know until we go to sell the house. I think this will be an asset for re-sale. Plus, we haven't had time yet to understand the difference in our fuel bills. I know the difference in the sound because there is heavy construction outside and I can't hear a thing. The sound value is much much better! With our old windows you could literally feel a draft. They are drilling in my front yard as we speak and I can't hear it through my new windows.
