Fire Attenuation

Crimsafe Fire Attenuation screens are a performance-based solution, designed to meet the National Construction Code of Australia to help reduce the level of radiant heat and spread of fire.

A Fire Engineer / Certifier will provide a Fire Safety Report which will describe what fire protection products are required to protect the building. Screens can be assessed by a Fire engineer / Certifier as a solution to limit the potential for fire spread occurring between buildings via radiant heat.

When tested, Crimsafe screens have achieved 59% attenuation rating in accordance with AS1530.4:2014. Fire attenuation screens can offer protection to window openings to buildings with property boundaries closer than 3m, or within 6m of adjacent buildings on the same allotment.

Crimsafe screens offer significant advantages over common ‘deemed to satisfy’ solutions, requiring far less maintenance and a lower capital investment. Screens are also a lightweight solution, preventing the need for over engineering and are an economical solution that offer not only fire attenuation but a multifaceted solution including security and insect protection, solar heat gain reduction and fall prevention.

Product Details

Crimsafe Fire Attenuation Screens are engineered to the highest applicable standards. This is ‘best in class’, unrivaled by any other security screen product.

AS 1530.4:2014 “Methods for Fire Tests on Building Materials, Components and Structures” sets out the level of  process and conditions for testing Fire Attenuation products – this involves exposing the screen to a heat of 40kW/m2 for 90 minutes. Crimsafe screens were tested to exceed this blocking 59% attenuation for 150 minute duration.
