With ROCKWOOL insulation this will cease changing into a problem. Granulated rockwool should be positioned into containers or pots with loads of drainage holes within the base. In distinction, the extra generally used vitreous fibre wools produced since 2000, together with insulation glass wool, stone wool, and slag wool, are thought-about “not classifiable as to carcinogenicity in people” ( Group 3 ). Among the many applications are thermal insulation together with both pipe and structural insulation, filtration, hydroponic medium development, and soundproofing. All insulation products have an embodied energy and carbon cost (though by some analysis cellulose is carbon negative, since it’s effectively sequestered carbon.) At a given R worth the typical rock wool answer has considerably more carbon footprint than fiberglass (means less than 2x) and fewer than any foam insulation. Rock Wool is a 4 digit HS92 product. Rockwool is a mainstay of commercial hydroponic growers – and for good cause.
