Mineral Wool

Mineral wool is made of inorganic fibers derived from basalt, a volcanic rock, in semi-rigid to rigid board form. Advanced manufacturing technology ensures consistent product quality, with high fiber density and low shot content, for excellent performance. Designed to be installed between spandrel panel and floor slab in commercial curtain wall systems, it provides a fire-rated seal. It is inorganic and will not support mildew or support corrosion. Mineral wool is available plain or faced.
