CLASS A FIRE RATING Mataverde® Decking and Siding Species

 

Mataverde Decking and Siding Species Tested and Meet Standards for Class A Fire Rated Decking

With new changes to the fire safety codes being adopted and implemented throughout the world, here are some resources that should help you choose the right materials for your project design and build. Check with your local code officials to see what is required in your area.

The most stringent codes being used for decking and siding materials follow the IWUI (International Wildland Urban Interface) requirements. Very few real wood siding and decking materials meet these needs. But Mataverde ThermaWood FR Hem-Fir Decking and siding does meet these requirements.This remarkable product line uses Thermex-FR, a non-toxic, long lasting fire retardant treatment. Mataverde ThermaWood FR is classified as "ignition resistant".

Mataverde ThermaWood FR marries the best of worlds; thermally modified and fire resistant wood. The unique thermal modification process makes the wood incredibly stable, and rot and decay resistant. The wood is then treated under pressure, with Thermex-FR, a non toxic, environmentally friendly fire retardant treatment. 

 

Mataverde ThermaWood FR decking and siding meet the following stringent code requirements:

  • IBC (International Building Code®) 2018, 2015, 2012, 2009, 2006. Section 603.1
  • IRC (International Residential Code®) 2018, 2015, 2012, 2009, 2006. Section R802

OTHER FIRE TESTING METHODS AND AGENCIES:

The type of testing that the following Mataverde hardwood decking and siding species were tested for is commonly referred to as ASTM E84-10 "Standard Method of Test for Surface Burning Characteristics of Building Materials". It is a ten minute test measuring surface flame spread and smoke density.  This fire testing standard was established by ASTM International (formerly known as American Society of Testing and Materials). A Class A fire rating using the ASTM test method is the equivalent of a Class A fire rating from the following test methods and agencies:

• ANSI/NFPA No 255 from the American National Standards Institute/National Fire Protection Association

• IBC 8.1 from the International Building Code

• UL 723 from Underwriters Laboratories

 

Several Mataverde hardwood decking and siding species have been tested for their performance in flame, smoke and fire testing. Mataverde Ipe hardwood, Mataverde Cumaru hardwood and FSC® Certified Mataverde Machiche, Mataverde Jatoba (Brazilian Cherry) hardwood all surpassed the E84 fire test criteria earning them a 'Class A' fire rating.
