This is my concern. They don’t have a great track record with extracted and mineral-based products. Drywall. Lead. Toys. Food. ...<BR>

House here recently had of all its brand new drywall and granite counters (all from china) torn out due to very high radiation levels. I am not sure how trade products could be cleaned up (few regulations in china) or import products effectively monitored. It is worrisome. Not sure if it is fair to single out china but it is the major exporter of cheap products to support our need for cheap building products.<BR>

What’s the word on the efficacy and usability of magnesium oxide-based sheetgoods to use in lieu of sheetrock, such as GreenEBoard, Dragonboard, or Magboard? All of the aforementioned are Chinese manufactured, which gives me pause. Is anybody aware of a North American made option?<BR>
<BR>
Can builders use them without thinking about how different it is from drywall?<BR>
<BR>
Thx,<BR>
