Why is it important to verify the manufacturer's data sheet for fireproofing products?

Verifying the manufacturer's data sheet for fireproofing products is crucial because it provides specific information regarding the required thickness of the fireproofing material and the application techniques that must be used to ensure effective performance. Fireproofing materials are designed to meet rigorous fire safety standards and building codes; thus, adhering to the manufacturer's specifications is essential to achieving the intended fire resistance rating. These specifications typically include detailed guidance on how to properly apply the material, including the recommended thickness, to ensure that it functions as designed in a fire scenario. Proper installation according to these guidelines is critical for the safety and compliance of the building structure being protected.
