Invisi-Gard by Verosol Fire Attenuation Testing

Fire attenuation, simply put, is the lessening of energy as a result of the presence of a screen.

Prevents the spread of fire

The screen’s presence reduces the amount of energy passing through to an observer from an energy source from what would be the case had the screen not been in place between the source and the observer.

The Building Code of Australia requires fire attenuation screening to certain classes of building based on the distance from the designated fire boundary or from other buildings on the same allotment, and dictates the incident energy to be applied to the attenuating screen.

Invisi-Gard by Verosol Fire Attenuation Screens is deemed to satisfy solution referred to in section C3 Protection of Openings in the National Construction Code.

Invisi-Gard by Verosol Fire Attenuation Screens are designed to protect window openings that are less than 3m from a property boundary or within 6m of another building in the same allotment.

Their purpose is to reduce any radiant heat transmitted from one area to another, helping to prevent the spread of fire between buildings.

AS1530.4-2014 APPENDIX B7

Test numbers: 52577300a

Achieves a fire attenuation rating of up to 55% at 40kW/m2 incident energy

Provides protection to limit the potential for fire spread to occur between buildings via flames and/or radiant heat.

Invisi-Gard manufactured by Verosol has been tested up to an irradiance heat of 40kW/m2 in accordance with AS1530.4:2014 Appendix B7 for a period of 130 minutes. The average percentage of heat blocked by the screen during the duration of the test is measured.

Invisi-Gard manufactured by Verosol achieves an attenuation of up to 55%
