Anyone with experience with Graef Thermal-weld

[whineyweim]

Hello everyone-

Does anyone have any recent experience with Graef windows, specifically the Thermal-weld series? I don't see much mention of them on this board or the internet in general.

I have had quotes on Graef, Gorell 5300 and Vanguard (Sunrise). It seems that when I compare the U numbers, they are pretty similar in general (foam filled frames, Low E, Argon,)

Let me know what you think of Graef.

Thanks.
