Originally created for its insulative qualities, rock wool has long been used within the horticulture industry for rising crops. Some growers pour water into the rockwool slab before the drainage holes have been reduce to make sure all the pieces has had a great drenching, whereas others simply pour water on or run the irrigation long sufficient for saturation to happen. The ensuing rock strands are compressed and bound together to create a bundle of mineral wool able to be simply reduce and used in any insulation job you’ve got coming subsequent. We need to proceed to harm Rockwool the place it counts, in the pockets, by pushing forward on the boycott and divestment campaigns. I would thought that rockwool was a byproduct of steel smelting and thus had a very low carbon enter (presumably we’d be making that steel anyway). The rockwool needs to be fully saturated so that all of the materials is wetted and then left to drain. In case you’re questioning, between 16% to 40% of Rockwool is made out of pre-consumer recycled material. Unlike regular wool, rockwool may be dyed from any colour into another shade.
