Perfect for music lovers (or noise haters), Rockwool is the preferred option to add soundproofing and fireproofing to improve your structure’s thermal and acoustic performance. The original idea of mineral wool insulation came from volcanoes. The first manufacturers of stone wool observed the way that lava became spun and twisted by gusts of wind. What if this cotton candy lava were poured into molds? The result became the incredibly sound resistant product known as mineral wool. With insulation characteristics similar to fiberglass, mineral wool excels in extreme fire Resistance. These products can withstand temperatures of up to 2150°F without melting, smoking or propagating flames.
