Calcium Silicate Board Gains Traction in Tunnel and Marine Applications

A consortium of civil engineers recently published a study demonstrating that autoclaved calcium silicate boards outperform fiber-cement panels in freeze-thaw cycles and chemical resistance. Major metro expansions in Shenzhen and Mumbai now specify these boards for tunnel linings and station interiors. In the marine sector, shipyards are adopting thinner yet stronger calcium silicate sheets for cabin partitions, achieving significant weight savings without compromising fire safety. The global market for calcium silicate boards is expected to grow at a CAGR of 6.2% through 2028.
