Thermal Industries vs. Okna vs. Tri State
Hi. I'm in the process of researching/gathering prices to have 14 double-hung replacement windows (with full grates) installed, as well as 2 large picture windows. Through this and other forums I've heard that Okna are very good (I was quoted for D-400s with a special that Window King is offering through Angie's list), and I've read that Tri-State are good as well (currently they are offering their top of the line 5400 windows for the price of the low end 4100). I haven't found too much information on Thermal Industries (though after seeing all of the windows they all seemed about the same). So far I've received the following quotes (per window):
Thermal Industries: $550 including grates + $600 for each picture window
Okna D-400: $400 + $60 for grates (so $460/window) + $475 for each picture window
Tri-State 4100: $540 + $50 for grates (so $590/window) + $850 picture window
Tri-State 4200: $590 + $50 for grates (so $640/window) + $950 picture window
Tri-State 5400: $640 + $50 for grates (so $690/window) + $1,050 picture window
Tri-State 5400 (at 4100 price): $540 + $50 (so $590/window) for grates + $850 picture window
The 4200 and 5400 are triple pane, and the 5400 has Krypton. All other windows above are double pane with Argon.
The Tri-State seem very expensive but have a lifetime warranty, and the special on the 5400 is intriguing.
In summary, the 14 double-hung with grates and 2 picture windows with grates comes out to the following:
$8,200 for Thermal Industries (double pane w/ Argon)
$7,390 for Okna D-400 (double pane w/ Argon)
$9,960 for Tri State 5400 (triple pane w/ Krypton)
I'm leaning towards the Okna because not only are they the cheapest given the Angie's List deal, but I've heard great things. However, for an extra $2,300 is it worth getting the triple pane with Krypton TriState 5400? We're replacing original 1970s (single-pane) windows so anything should be a vast improvement.
I'd love to hear your thoughts, comments and suggestions.
