I'm as annoyed by cheap construction and cut corners as anyone. We save a few cents upfront and pay to eternity in crappy efficiency or longevity.
Tough for the average person to know what improvements are worthwhile, and which aren't.
Glass companies are always trying to sell low E windows here claiming great energy savings. We have 3 cooling months which require maybe 2hrs of AC use per day. The rest of the year I'm depending on the emissivity of the glass to gain free heat.
How would someone know that low E glass makes no sense here when the "expert" is telling them it will save so much money?
