SUPERLON CLASS O

While thermal conductivity and water resisting performance have always been the key elements in determining the functionality and effectiveness of an insulation product, fire resistance have increasingly gained importance for its role in preventing fire spread.

Superlon Class O prevents flame spread and fire propagation and is tested under British Standard (BS) 476 part 6 and part 7. Part 6 (fire propagation) measures the heat release under fire conditions and part 7 (spread of flame) measures the ability to retard flame spread under fire conditions.

The most common disaster in a building is often a fire emergency. The quality of building materials play a decisive role in determining whether a fire can be contained and extinguished quickly. In the event of fire, pipes and ducts are usually the main reason for fire spread as they are interconnected throughout the building. It is important for these to be fire resistant.

Should insulation material be used in buildings whether air conditioning pipes, chiller lines, heating pipes or ducting, Superlon Class O should be an integral part of the building where fire performance matters.
