Understood. I've been checking air infiltration and other ratings, I'm concerned with deal failures. Based on other comments in regards to the mezzos they have a high seal failure. I looked up the great lakes and saw some comments on seal failure. I just don't want that to be an issue in any of my windows.HomeSealed wrote: ↑Sun Apr 05, 2020 5:02 pm Argon gas loss rate is a non-issue as long as you are talking about reputable manufacturers and assuming that the seal has not failed.
Take a closer look at the air infiltration and DP rating. That will tell you good bit as well.
It seems like Restorations is going to be my choice. I saw that the company pushing the plygem great lakes also have a partnership with Softlite so I'm going to inquire about those.
