Salvaged Windows and Energy Efficiency
We are preparing to do a new build. I would like to add a few salvaged windows. Mostly we plan on using new, but I want to put a stained glass window over the soaking tub and a gothic style or similar in the front of the house (kids' bathroom) My husband is very concerned about these being as efficient as just a hole in the wall. Is there some technique used to seal these up so they don't ooze cold air in the winter and hot air in the summer?
We haven't purchased the windows yet, is there anything I should be looking for that make them better or worse?
