Intumescent

A substance that swells as a result of heat exposure, increasing in volume and decreasing in density.

Intumescent materials swell when exposed to heat, providing fire protection by forming an insulating char. They are crucial for enhancing fire resistance, protecting structural elements, and ensuring safety compliance. By delaying heat transmission and structural damage, intumescent coatings support fire safety strategies, reduce risks, and ensure that buildings meet fire resistance standards, contributing to successful project delivery by ensuring that structures are protected and aligned with safety requirements.
