Doors and Windows - Storm Windows-Which are best-2 or 3 track

I'm about to install storm windows that I don't think will ever be opened. Are 2 or 3 track better? Also any particular brand of windows that give a better seal? Anything thing in particular I should look for in windows?

Three track are more practical to use but since you're never going to open them, two track will be OK. Look for a window with butt fit corners on the master frame and sashes with pile and interlocking meeting rails. If you are in a high wind area, anti-bow pins is a good option.

I'm curious, why are they never going to be opened?

A storm window that doesn't open(1-piece) is called a 1-lite reverse-reverse because it removes to the outside.These are cheaper and more durable than the multi-track variety for obvious reasons.However, keep in mind that the fire marshall would be very upset if provisions are not made for a hasty exit in case of emergency.

Well, its not like they will never be opened, but rarely. Our house has central air and we like it cool.

I thought that the good windows had rubber for seals, not pile? It would seem to be tighter. Also when you say butt fit, is this opposed to mitered?

Thank you for the help.
