The Global Flexible Fire Protection Sealants Market was valued at USD 734 million in 2023 and is projected to reach USD 1009.10 million by 2032, growing at a Compound Annual Growth Rate (CAGR) of 3.60% during the forecast period (2023–2032). This growth stems from stringent fire safety regulations and increasing adoption in commercial and industrial construction projects worldwide.

Flexible fire protection sealants play a critical role in modern construction by sealing joints and penetrations in fire-rated assemblies. These advanced materials prevent the spread of flames, smoke and toxic gases while offering additional benefits like acoustic insulation and weatherproofing. As building codes become more rigorous, the demand for high-performance fire stop solutions continues to rise.
