Rockwool offers an amazing fit and won’t sag or droop, so delivers long term efficiency. Fiberglass insulation however will lose R-Worth over time if exposed to water vapor. Manufacturers use a mechanized process to spin a molten composition of rock and slag into excessive temperature-resistant fibers. So we partnered with them to get the word out as a result of we consider in Rockwool. This investment will allow us to raised help the Romanian government’s efforts to increase fireplace security and power effectivity in the nation’s buildings,” ROCKWOOL Group vice president Gilles Maria said again in 2017 when the funding was announced.
