Insulating Window Inserts Anyone?

Question

Has anyone tried insulating window inserts? I have properties with older windows. The windows are still solid, but are not good at insulating. These inserts seem to solve that problem and are quite cost-effective.

At a quick glance this looks to be the same concept of placing plastic sheets over the windows during the winter months.  This will change the function of the window to a "fixed" non-operable window when installed.  I see this a something that will pulled out from time to time during the year to open the windows and get fresh air.  For the price its worth trying one.  I would not consider this a permanent fix to the problem.

That is economical (and I assume it doesn't include labor).

Pocket windows or sash replacements are unlikely to come close; although there are some down and dirty vinyl products that can be had for around $100, depending on size of course. I'm not advocating down and dirty though...

@Scott Weaner, I'm not familiar with these inserts, but my first thought was condensation build-up between the existing sashes and the inserts.

When you say older, about how old are we talking about?

Have you considered replacing just the sashes with insulated ones or from an economy standpoint, using vinyl pocket windows?

Thanks Account Closed. I really haven't even investigated replacing anything yet. A tenant commented on the windows. The windows are probably 30 years old, but still work fine.

What is the cost of doing what you have suggested? The inserts that I referenced are $40/window, so very economical.

I looked into a company Indow Window out of the PNW. http://www.indowwindows.com/indow-window-reviews/

Got a quote for about a $400/per.  Figured that was almost the price of a new window. I don't have an issue with historic accuracy, so decided to buy new instead which will be just a bit more expensive.
