Type V-A (wood frame, protected) is rated at how many hours?

Type V-A construction is classified as wood frame construction that has been protected with a fire-resistive covering, typically through the application of fire-rated gypsum board or other similar materials. This protection provides a degree of fire resistance, which is rated at 1 hour.

The importance of the 1-hour rating lies in its application in building codes and standards, as it informs fire prevention practices, emergency response strategies, and safety regulations. Buildings constructed with Type V-A materials are designed to withstand fire exposure for a certain period, allowing occupants time to evacuate safely and providing firefighters with a more manageable timeframe to address the incident.

The other ratings mentioned correspond to different types of construction or specific building features that provide longer durations of fire resistance, which do not apply to Type V-A structures. Understanding these ratings is essential for fire fighting and safety planning in diverse building scenarios.
