I gotta admit, I used to think Owens Corning was only about pink insulation and that's it. But then I found out they’ve got like 25,000 people working in 31 countries, which is wild. I think what makes them pop off globally is that they're not just huge—they go out of their way to offer more than just basic stuff. Like, companies want building materials that are reliable but also help them follow all these new rules about being green or energy efficient. OC is always showing off how their products help big companies stay out of trouble with environmental laws, and that seems to be a big selling point (especially when you hear about FOAMULAR stuff).

Plus, having a recognizable name gives them a leg up when big projects are looking for trusted suppliers. I've heard my uncle, who’s in construction, say that big contractors love using Owens Corning because it's easy to get everywhere, and their support actually helps sort problems if something goes wrong. So I guess it’s a mix: they're big, but they also try pretty hard to make their stuff meet new needs. Makes sense why they’re a go-to for companies all over.
