Fire-Rated Aluminium Attic Ladders
The AM-BOSS INFERNO-BOSS™ is an advanced fire-rated aluminium attic ladder, designed to provide safe and reliable access to attics or overhead spaces while meeting stringent fire safety requirements. Tested and engineered to withstand extreme conditions, the INFERNO-BOSS ladder offers both convenience and crucial protection in case of a fire.
The ladder’s fire rating is measured using a Fire Resistance Level (FRL), which denotes the number of minutes a product can maintain its fire protection properties. The FRL includes three key performance criteria: Structural Adequacy, Integrity, and Insulation. Since the Fire-Boss Ladder is a non-loadbearing system, it is exempt from the structural adequacy requirement, represented by a dash in the FRL rating (– /90/90). The second number (90) refers to Integrity, which means that the ladder will maintain its structure and prevent the passage of flames and hot gases for 90 minutes during a fire. The third number (90) refers to Insulation, which indicates that the ladder will prevent heat from transferring through for 90 minutes, helping to protect the area above or below it during a fire.
The INFERNO-BOSS Ladder was rigorously tested in 2013 and demonstrated a load capacity exceeding 200kg at four key structural points, ensuring its durability and safety during regular use. This impressive load-bearing capability makes it suitable for accessing storage areas or conducting maintenance in various residential, commercial, or industrial settings.
Compliant with Australian Standard AS1530.4-2005, the INFERNO-BOSS Ladder boasts a high fire resistance rating of – /90/90, reflecting its superior performance in fire tests. It is manufactured from strong, welded aluminium, making it not only fire-resistant but also highly durable and long-lasting. The ladder’s robust construction includes a width of approximately 400mm and features 75mm-deep stiles and treads, providing ample stability and comfort when climbing or descending.
Designed to be installed at an optimal 68-degree angle, the INFERNO-BOSS Ladder is suitable for ceiling heights up to 3000mm, making it a versatile solution for a wide range of building types. Its lightweight yet sturdy aluminium frame allows for easy operation, while the fire-rated properties offer peace of mind in any environment where fire safety is a concern.
The AM-BOSS INFERNO-BOSS Ladder combines practicality, strength, and superior fire protection, making it an essential component for buildings where safe attic access and fire-rated materials are necessary.
