I have never heard of Hayfield. As for CertainTeed, I am not aware that they are making windows any longer as Ply Gem bought their window division. Ply Gem makes various lines and some are better than others so more info is needed.
Certainteed is a mess. PlyGem only bought their west coast product, around here they still sell them as Cetainteed through some vendors, others label it an MI or one of it's many aliases.. It's not a great window... I know nothing at all about Hayfield.
