What is the maximum flame spread index for wall and ceiling finishes?

The correct answer is: 200

The maximum flame spread index for wall and ceiling finishes is set at 200. This index is part of the criteria used to evaluate the combustibility and fire safety of materials used in buildings. A flame spread index of 200 means that the material has a relatively higher resistance to flame spread compared to materials with a lower index. This standard is important for ensuring that finishes used on walls and ceilings do not contribute significantly to the rapid spread of flames in the event of a fire. Materials with a flame spread index higher than 200 would be considered less safe and would not meet the necessary building codes for interior finishes in residential settings. The values below 200 indicate better performance in fire resistance; however, materials scoring above this threshold could pose a higher risk. Understanding these limits is crucial for inspectors when assessing compliance with fire safety regulations in residential properties.
