Product Criteria

Design requirements

FireZone™ F1E’s intumescent technology is designed to protect exterior timber substrates and reduce the spread of flame from one building to another and vertically up a multi-storey building.

The coating forms thick char layer insulating the substrate from heat., preventing ignition or flame spread on the coated surface. Specify FireZone™ F1E over timber substrates when a non-combustible Type A or Type B cladding classification is required.

This is typically when the wall is within 1m of a boundary line or the height of the wall is over 10m.It is a highly durable and flexible product, designed for external use as an industrial coating.

Specify an acrylic exterior paint finish as the final coat for choice of finish.

Installation requirements

FireZone F1E must be applied either on or offsite by an Zone Architectural Products approved applicator.

Please see the FireZone F1E system data sheet for in depth installation requirements.

Maintenance requirements

The system has achieved it's fire performance classification after the requirement accelerated weathering regime of ASTM-D 2898 Method B without a topcoat.

The system should be checked by the builder owner or maintenance team for to ensure the integrity of the coating is maintained. Please contact Zone Architectural Products for further information.

The decorative topcoat should be maintained as per the topcoat manufactures requirements.
