Low E on storm windows, worth it?

berkeley223June 26, 2013

I am considering getting ProVia storm windows to go over my drafty original wood windows. Low E costs about $600 more for all windows. Is this worth the expense?

How many windows?

15 windows. If LowE makes some sense, does it makes sense to only do it on some but not all, to save $$?

In my opinion, at $40 per unit it is worth it. Not only will it save money in terms of energy efficiency, it will preserve your prime window units and further protect your window treatments, carpet, furniture, etc from UV damage.

Definitely a worthwhile investment.

It will more than pay for itself over the life of the storm window.

Agreed. I'm staunchly against energy savings "guarantees", pay back schedules, etc, however there is no question that the low e upgrade will pay for itself completely independant of the other added benefits. A 10 yr payback should not should be completely out of the realm of possibility.

I decided to get the Low-E on all the storms. I went with the ProVia concord storms and repairing the original wood windows to my 1920s home, instead of replacing them with Okna 800s, which was my other option I was considering. Thanks for all the good advice and I'll post later on how it all worked out.

Whether or not you made the best choice will depend entirely on how your original windows end up after the restoration process and associated cost, however the Provia storm is a very good unit and the low-e was wise as well. Good choice in that regard :)

What is included in the restoration of your older wood window?

for the restoration (really repair) they are unsticking every window, fixing the broken pulleys, scraping all the paint off the glass. basically getting all windows in working order, but not doing any weatherstripping, which is what I hope the storms will aid in.

According to a study conducted by the U.S. Army Cold Regions Research and Engineering Laboratory (USACRRE) and the State of Vermont in 1996, the annual energy savings of adding low-E coating to a window/storm window combination is $2.57 per window per year. This is, of course, based on the cost of energy in Vermont in 1996. It may differ where you are today. But it's probably a good ballpark number.
