I'm just wondering if anyone is using GBCI's Better Materials site as their go-to source for transparency and healthy materials.  Having all the search engines on one platform is great in theory, and I keep hoping that it will be the one-stop site/resource that I can get all our designers to use.  Unless I'm missing something though, it still...

Thanks and I hope everyone is... Read more
