No, I'm not talking about how I'm not connected to Kevin Bacon. I've been running a very unscientific experiment with the new interior storm window and any heat loss or gain. Using a small indoor/outdoor digital themometer I've determined that on average there is a four degree difference between the added storm and the "normal" window. Not bad. But the biggest difference is the reduced draftiness. Just think about how much less gas the furnace will use when all the windows are done!
