 I never even think about this stuff because, you know, that there would ever be a concern because I use Pella. And when you use Pella, you don't have to be worried about stuff like that. I could go on and on about this issue, but it's just not an issue with Pella windows and doors. And the folks in Mishawaka at the Pella showroom here, they are the most wonderful people.
