How must sloped glazing and skylight frames be constructed in type 1 and 2 buildings?

Of non-combustible material
Of wood
Of plastic
Of treated metal

The correct answer is: Of non-combustible material

Sloped glazing and skylight frames in type 1 and 2 buildings must be constructed of non-combustible materials to comply with safety regulations and building codes. Type 1 and 2 buildings are classified as non-combustible structures, meaning their construction should utilize materials that do not ignite or contribute to the spread of fire. Using non-combustible materials in sloped glazing and skylight frames enhances fire safety, reducing the risk of structural failure and limiting the potential for fire-related hazards within the building. This requirement helps maintain the integrity of the building during a fire event, ensuring safer exits for occupants and better protecting adjacent structures. Furthermore, the use of non-combustible materials is consistent with the overall design intentions for these types of buildings, which prioritize durability and fire resistance. In contrast, options that include wood, plastic, or treated metal do not meet the stringent fire safety standards required for the construction of sloped glazing and skylight frames in these building types, which is why they are not acceptable choices.
