Okna Triple Pane Upgrade
I am new this forum but have read many of the postings, thank you to all for the great information. I have decided on using Okna replacement windows for all 20 DH windows in my house which in eastern PA and my question is this.
The upgrade from double pane, low e with argon (.25 U-value) to triple pane, low e on surfaces #2 & #5 with ARGON (.19 U-value)cost an additional $1280 which equates to an additional 12% on the total cost (including installation).
Would this be well spent money or are the triple pane overkill for this area. I want to be efficient, but don't want to be wasteful and never recoup the upgrade cost in energy savings.
Your opinions are greatly appreciated !
