Spray Applied Fireproofing

Spray Applied Fireproofing

Spray applied fireproofing materials are passive fire insulation solutions developed to protect structural elements against the effects of high temperatures and flames. Applied by spray method especially to steel, concrete and masonry surfaces, they delay the heat generated during a fire from reaching the load-bearing elements directly. This protection is vital for materials such as steel, which can rapidly lose strength at high temperatures. Thus, the building's structural system maintains its stability for a certain period, gaining the critical time needed for safe evacuation and intervention.

These materials containing cementitious binders form an effective thermal barrier thanks to their low thermal conductivity. After application, a monolithic and rough surface is obtained; if desired, it can be smoothed with a trowel or the topcoat appearance can be improved with suitable coatings. Their lightweight structure does not add extra load to the structural system, while they can provide fire resistance of 120 to 240 minutes depending on thickness and density values.

Spray applied fireproofing materials not only provide fire protection but also contribute to thermal and sound insulation. Their high sound absorption capacity improves acoustic comfort and helps create drier, healthier interior conditions by reducing the risk of condensation. Thanks to their natural and inorganic content, they are long-lasting; their composition free of harmful or toxic components is consistent with the understanding of sustainable construction.

Spray applied fireproofing materials, which have a wide range of applications from steel columns and beams to reinforced concrete slabs, from industrial facilities to car parks, are one of the fundamental components of passive fire safety in modern buildings. While enhancing the overall safety performance of the structure, they also contribute to energy efficiency and environmental sustainability goals.
