4. Foam Insulation:
Foam insulation materials, such as polyurethane or polystyrene, are widely used in construction due to their versatility. While foam insulation may not be inherently fire-resistant, it can be treated with fire-retardant additives to meet the required safety standards. These additives help slow down the spread of flames, providing valuable time for evacuation and firefighting efforts.
5. Intumescent Coatings:
Intumescent coatings are a unique fire-resistant option that can be applied to various surfaces, including insulation materials. These coatings are designed to expand and form a protective barrier when exposed to high temperatures. By creating a shield, intumescent coatings delay the transfer of heat, preventing the ignition of surrounding materials and enhancing fire safety.
