Encore Windows by Armaclad?

[jgemberton]

Has anyone heard of or dealt with these windows? On paper, they have some of the best ratings for vinyl slider replacement windows - U-factor, SHGC, and Air infiltration all below .30. I'm really leaning towards windows with superior air infiltration ratings because I've found that even with the best U-factor, windows that leak air like sieves are pretty useless. I live in Southeastern Michigan and am replacing some bottom of the line windows installed by Hansons Windows 11 years ago.
