I have a bay window with low-e glass that I had installed 10 years ago. I have noticed that my curtains have faded somewhat. The curtains are only about 6 years old, and only get sun in the wintertime when there are no leaves on the trees.
Should low-e glass do this, especially after only 6 years. The glass does have a tint, and a sticker on them said low-e, so I doubt they're clear glass.
Just wondering how much UV low-e is really supposed to block.
Thanks.
