Hi Trev Interesting the customer mentioned about haze on the glass. I have had this said to me about 5-10 times in the last year or so. It always seems to be when the customer has new Windows. The first time it was said I investigated and found the Windows to be of cheap quality or they have a coating to confirm with energy ratings and it's the way they are made. If you imagine a normal window then inside that glass is a purple haze but is about 1 or 2 inches less than the size of the glass. Giving it a border inside. I will take a real photo of my customers Windows when I next see her. But here is what they look like. Instead of being at the top. The Windows has it all over but not quite up to all the edges.
