Rockwool from international suppliers (China)
It seems that a simple internet search turns up hundreds of sources of rockwool from China. This seems like a product which is dominated by a few (1?) suppliers here in North America. With some sleuthing, it seems like something that could be had for a lot less money per inch… I understand the possible downsides of unknown suppliers, but this seems like a widely used product outside of the NA market.
I also remember horror stories about Chinese drywall and laminate flooring. I am only considering this for subslab and exterior foundation insulation.
I don’t like getting everything from China, but I also don’t like how just a few suppliers/brands are able to dominate certain markets. The rockwool industry in China sort of resembles the EPS market here in NA. I will be getting a free sample from a few manufacturers and see if it looks like Roxul.
