It is this moisture gradient from the highest to the bottom of the rockwool materials that makes it such a good substrate. Some industrial tomato growers re use good quality rock wool for as many as 6 successive crops with use of steam sterilisation to control root pathogens between plantings. Rockwool insulation material has the power to face up to greater than 2150º F without melting, which means it significantly slows down the unfold of fire. Rock Wool Manufacturing Company. Rockwool insulation shields buildings and their occupants, bettering safety, comfort and constructing value. The way in which by which the molten rock fibres are stacked and the density inside the rock wool product determine the properties of the rising media such as the moisture holding capability, the aeration or air stuffed porosity and the moisture gradient from the top to the base of the dice or growing slab. Rockwool is an item added by Thermal Expansion It’s used as a dyeable decoration block similar to Wool , however is fireplace proof. Alex Wilson, the founder of BuildingGreen, wrote in 2013 that he was thrilled ” to study that Roxul (which has since been renamed to Rockwool) could be making its ComfortBoard insulation obtainable to residential builders.
