Sorry, they were comparable - Simonton-double hung, no grids, complete trim outside, argon, lowE, 1" IGU with foam superspacer, the Simonton was less expensive at $4300. The Thermal industries window was comparable bt wanted $8100 for 7/8" with argon in all. Simonton contractor wanted 1/2 down to start. Other offered financing on a credit card. Thanks for any advice obviously I need a couple more quotes here.
TI makes several lines of windows. Unless the dealer was showing you the Park Avenue, I go with Simonton.
