Triple pane IGU question
I'm looking at two manufacturers of uPVC windows. They use different frame profiles that are nearly identical, the colored foils are from the same supplier, the spacers and glass are slightly different but overall the specs are nearly identical. The price quotes are very close but structured differently so it's difficult to compare apples to apples. The biggest difference is their approach for higher alltitude installations. One uses a pressure release tube that is pinched at the final destination and only the units requireing it are tempered SG. The other uses a pre-pressurized system at the factory to set the internal pressure for final destination and then it's sealed. All panes are tempered SG. So is one or the other significantly better to choose between the two?
