Hey Jerry

In this new age of green and 13 seer minimum and so on isn't there something in some code somewhere that has to do with the minimum thermal and or double glazing. I could have sworn I've seen some thing but can't remember where.

What are your thoughts on the bath window that has safety on the inside but nothing outside. I have seen windows like that in the past where the heat build up between the pains warps the stain glass. What about minimum secutity and or moisture getting between the pains. It would be just like a broken seal between the double pain windows. You can lean on those windows and pop them in or out.

Thanks.

Still reading, can't find anything.
