The Firefree Exterior System has two components, Firefree Class A ("FfA") to provide the fire retardant protection and Firefree Exterior Topcoat ("FfE") which is applied on top of FfA to protect FfA from long term weather exposure.
For FfA, it needs to be applied first, with a thickness required of two coats (2) @ 10 mils dry each, for a total applied of 20 mils dry. The net coverage with the specified two coats is 53 sqft/gal (1.30m2/l). FfA then needs to be top coated with FfE, as follows.
For FfE, it needs to be applied to top coat FfA. The thickness required is two (2) coats @ 3 mils dry each; total 6 mils dry. Net coverage rate with the specified two coats: 110 sqft/gal (2.70 m2/l).
FfA has been tested to both the ASTM E 84 and ASTM E84 30 minute extended. FfA Testing
The Ff Exterior System (FfA top coated with FfE) has been tested to the ASTM E-84 30 minute extended test standard on 5/8” T-111 Douglas Fir siding. The ASTM E-84 extended 30 minute fire test standard meets the requirement for ignition resistant materials and is the same test standard used to rate chemically treated, fire rated lumber. The Ff Exterior System has also been tested by Firefree to methods similar to the ASTM D 2898 Method B weatherization test with follow up fire testing to the ASTM E 1623 I-Cal.
When subjected to wildfires, structures are exposed to two different types of fire, (i) high end radiant exposure when the fire gets close to the structure, generating intense heat, and (ii) flame exposure when the fire actually reaches the structure. The Firefree Exterior System is unique in its testing methodology as it has been tested to both high radiant exposure (1623 I-Cal) and flame exposure (ASTM E 84 30 Minutes Extended).
Firefree Class A is listed under LEED compliant paints and coatings in accordance with CDPH Standard Method v1.2, 2017 emissions. It should be noted paints earn LEED v4 Emitting Materials credit for being emission certified in addition to meeting CARB SCM 2007 VOC limits.
Fire Safety. For various reasons, including (i) the very different circumstances that may exist from one fire to another, (ii) the differences between conditions in an actual fire and laboratory conditions in which testing is conducted, and (iii) the inherent variability of fire tests, passing a laboratory test or certifying/labeling either Ff88, FfA or FfE (each a “Product”) for use in specific assemblies/systems does not mean that the same application of any such Product will necessarily provide an equivalent protection or the same result in an actual fire or in a new laboratory test. Furthermore, each Product, or combination thereof, is to be used only as a component of complete fire retardation systems. Ff88 or FfA will only contribute to slowing fire spread for the area where it has been applied and will not, by itself, prevent a fire from starting or continuing. The amount by which Ff88 or FfA retards a particular fire will depend, among other things, on (i) the amount of Ff88 or FfA applied, (ii) the conditions of the other elements of the assembly incorporating Ff88, or FfA, and (iii) the conditions of the actual fire itself. Ff88, FfA or FfE will not make a fire any less dangerous to persons or property. Firefree cannot guarantee that loss or injury will not be suffered by persons or property. It is the sole responsibility of the applicator to ensure that each Product has been applied in accordance with the application directions. It is the responsibility of the occupier to ensure the paint is not cracked, chipped or peeling.
