Rock wool has the characteristic of allowing a grower a greater degree of control over the foundation zone and this can be used to assist ‘steer’ crops into either a extra vegetative or generative progress. While the typical fiberglass insulation product contains 20 to 30 p.c recycled content, in accordance with the U.S. Division of Energy, rock wool consists of seventy five p.c recycled content or greater, making it a more eco-pleasant choice for those concerned about recycling. This greater density allows rock wool to cut back sound transmission via a wall by around 10 decibels, while fiberglass insulation reduces sound transmission by as few as four decibels, or as many as 10, relying on the fabric and how it is installed.
SEM analysis confirmed a bigger reduction of length-weighted geometric imply fiber diameter at 4.5 pH than at 7.four pH.
