[quote=Edchris177]Thanks for the info, seems there is lots more to windows than just sticking glass in a hole!
I'm in a cold climate, we use double or even triple glaze by code, argon is an option. I had doubts as I had heard that the argon all leaked out within 2 years. The manufacturer told me nowadays it's good for 10+.
You're right, how would a person ever tell if there was any in there or not. Maybe they just charged me a bunch of money & put plain old "air" in! The newb gets fleeced, again.
We use the heat reflection on the inside, to keep heat in, as we heat more degree days than we cool. This take advantage of passive solar heating. Houses are also designed to have no, or very small north facing windows, the opposite of what a hot climate would want.
The thread made me do some reading, I'm now better informed on what to use where, especially with regards to 5200.[/quote]
