Gorell only have a non metallic spacer in their "Ultramax" window. The 5300 Thermal Master is a ppg interecept which is a metal spacer. Starmark is one hell of a window. I think its one of the best windows out there. comparing the two. Starmark is going to have better numbers thank all Gorell windows.such as u-factor. its also a very good spacer thats non metal and not a regular vinyl like Gorell. I am also a fan of their lowE glass package. Okna also has one of the best warranties .
