I am going through my windows at my house. I want to keep the original windows which are dated back to 1850. I plan to air seal around them, reglaze them, and add weather stripping. I will mount double glazed interior storm windows for the winter. I may also put put the triple tracks that \are on there now back up. My question is has anyone used the window glazing in a caulk tube. It dries in like 24 hours compared to the month for regular glazing. Ive tried both on a old storm to see how I liked it. It didnt look as finished or smooth as regular glazing. What are your experiences?

Putting up interior storms-only subjects the antique windows to greater moisture accumulation/colder temps- it's hard on them. Rather than interior storms & clear-glass triple-tracks, put up the tightest low-E exterior storms, which will keep the antique windows warmer/drier, and skip the interior storms.

Harvey makes some of the tightest storm windows on the market, and has a hard-coat Low-E glazing option, but the better-grade "Gold" series low-E Larsons (available through box stores) also aren't bad- WAY tighter than typical triple track storms.
