That is impossible to figure out with all the varibles and still difficult with them.. Some of the varibles would be Location, cost difference, how long you plan to stay in your home, cost of energy, How many windows, size of windows and more.

I’d lean towards triples if you planned on changing out the others in the futue depending on location. If plan on selling or leaving the others I would go double pane.

Toddinmn,

Thanks for your advice. The current windows are 2 paned. Is there any technical issues that I should aware of if change to 3 paned? I only know that the window will be heavier. Thanks

The glass may look different / darker and may be noticable if on the same elevation. This could also happen with dual pane as well,

Toddinmn,

Thanks! Do you know if Simonthon is better than American Craftsman? Or vice versa. I saw bad reviews in Home Depot.

Everything is better than American Craftsman. Even if they are free, look elsewhere.

Oberon,

Lol, thanks. My current windows are American Craftsman. So, I'm looking for something a little better, but not break the bank.

Simonton better for sure, there are usually better than that available though.

Big nod to the brand that Todd mentioned in this comparison.
