What is the fire resistance rating of all elements of Type V construction according to PD 1096?

In Type V construction, all elements are made of combustible materials, such as wood. According to PD 1096, these types of structures typically do not require extensive fire resistance ratings, unlike more robust construction types. The required fire resistance rating for Type V construction typically aligns with a much lower standard than options suggesting 2, 3, or 4 hours.

However, it's important to note that while specific conditions may vary depending on local codes and the intended use of the building, the standard for Type V usually does not dictate a fixed fire resistance rating of 5 hours, as that is significantly higher than what is generally required. Under normal circumstances and based on the international guidelines that can be referenced in PD 1096, Type V construction typically stands with a lower benchmark for fire resistance than what is represented in the other choices.

Therefore, understanding the context of building codes and their fire resistance specifications clarifies why Type V construction, dealing primarily with less fire-resistant materials, would not hold a rating of 5 hours, making the selected answer valid in that context.
