If you're speaking about Thermal Industries Park Ave, I can only say that TI is a solid company. They stand behind their product well. However, I don't like the asthetics of the PA line. I do have 6 of their SPD's in my Sunroom and I like them.

is OKNA a better window? how does it compare? looks and performance?

[buddy110]

I did see the Onka composite and it has some pretty good numbers. The aesthetics were more pleasing than TI. But aesthetics are subjective. You may like the TI better. TI also has good numbers and like I said they're a solid company. Okna is a smaller boutique typ manufacturer than TI

lets compare the Okna 500 series with Park ave. i think they are both have solid u-values under 20. is it difficult to say one is better? if you compare looks of park ave and the 500 series(nor composite),which is nicer looking?
