Always 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 SaferWood Fire Retardant Treated Decking, Siding, Fencing and Structural Lumber all meet these rigorous safety requirements. This remarkable product line uses Thermex-FR, a non-toxic, long lasting fire retardant treatment. Mataverde SaferWood is classified as "ignition resistant".    ![ThermaWood FR Hemlock fire retardant treated T&G vertical siding on second floor exterior with majestic mountain views](https://www.mataverdedecking.com/hs-fs/hubfs/ThermaWood%20FR%20Hemlock%20fire%20retardant%20treated%20T%26G%20vertical%20siding%20on%20second%20floor%20exterior%20with%20majestic%20mountain%20views.jpg?width=973&height=648&name=ThermaWood%20FR%20Hemlock%20fire%20retardant%20treated%20T%26G%20vertical%20siding%20on%20second%20floor%20exterior%20with%20majestic%20mountain%20views.jpg)*Mataverde SaferWood ThermaWood FR Hem-Fir siding, treated with non-toxic Thermex-FR meets the latest fire codes* 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. To make this fire treatment exceptionally long lasting, the wood is then kiln dried after treatment.   Mataverde SaferWood meets 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 - IWUI (International Wildland Urban Interface) - WUI (Wildland Urban Interface) - E84/723 Extended for 30 minutes * Always check with local code officials to see what is required in your area.   [DOWNLOAD MATAVERDE FIRE-RETARDANT-TREATED WOOD ESR-1159 WUI EVALUATION REPORT](https://www.mataverdedecking.com/hubfs/ESR-1159%20WUI%20Evaluation-June%202021%20Mataverde%20Fire%20Retardant%20Lumber.pdf)   [VISIT FIRE RETARDANT TREATED LUMBER WEB PAGE FOR ADDITIONAL INFORMATION](https://www.mataverdedecking.com/mataverde-fr-fire-retardant-treated-lumber)   --- ## 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.  *![FSC Machiche hardwood on backyard deck](https://www.mataverdedecking.com/hs-fs/hubfs/FSC%20Machiche%20hardwood%20deck%20with%20dining%20and%20entertainment%20space-1.jpg?width=600&height=372&name=FSC%20Machiche%20hardwood%20deck%20with%20dining%20and%20entertainment%20space-1.jpg)* *An example of FSC Certified Machiche Decking * --- ## MATAVERDE WOOD SPECIES ASTM E-84 TESTED: From a safety standpoint, fire resistance is a very important criteria for building design and construction. The following species were tested for their compliance with Class A fire rating criteria: [Mataverde Decking and Siding: Learn more about Ipe hardwood](https://www.mataverdedecking.com/ipe-decking/) [Mataverde Decking and Siding: Learn more about Cumaru hardwood](https://www.mataverdedecking.com/cumaru-decking/) [FSC Certified Mataverde Decking and Siding: L](https://www.mataverdedecking.com/machiche-decking-/)[earn more about Machiche hardwood](https://www.mataverdedecking.com/machiche-decking-/) [Mataverde Decking and Siding: Learn more about Jatoba (Brazilian Cherry) hardwood](https://www.mataverdedecking.com/jatoba-decking) ---   | ![1x4_ipe_decking_has_a_narrow_profile_for_a_great_linear_effect.jpg](https://www.mataverdedecking.com/hs-fs/hub/112655/file-16356215-jpg/images/1x4_ipe_decking_has_a_narrow_profile_for_a_great_linear_effect.jpg?width=250&name=1x4_ipe_decking_has_a_narrow_profile_for_a_great_linear_effect.jpg "1x4_ipe_decking_has_a_narrow_profile_for_a_great_linear_effect.jpg") | ![cumaru_deck_shows_exotic_graining_figuring_and_color_variations-133996-edited.jpg](https://www.mataverdedecking.com/hs-fs/hubfs/cumaru_deck_shows_exotic_graining_figuring_and_color_variations-133996-edited.jpg?width=250&name=cumaru_deck_shows_exotic_graining_figuring_and_color_variations-133996-edited.jpg "cumaru_deck_shows_exotic_graining_figuring_and_color_variations-133996-edited.jpg") | | --- | --- | | Mataverde Ipe Hardwood Decking | Mataverde Cumaru Hardwood Decking | --- ## DOWNLOAD COMPLETE MATAVERDE FIRE TESTING RESULTS: To view the complete specific Class A fire test results for each of these hardwood decking and siding species, please click on the appropriate link: [DOWNLOAD: Class A Fire Rating test data for Mataverde Ipe Hardwood Decking and Siding](https://www.mataverdedecking.com/hs-fs/hub/112655/file-30939711.pdf) [DOWNLOAD: Class A Fire Rating test data for Mataverde Cumaru Hardwood Decking and Siding](https://www.mataverdedecking.com/hs-fs/hub/112655/file-30939700.pdf) [DOWNLOAD: Class A Fire Rating test data for Mataverde FSC Certified Machiche Hardwood Decking and Siding](https://www.mataverdedecking.com/hs-fs/hub/112655/file-30939701.pdf) [DOWNLOAD: Class A Fire Rating test data for Mataverde Jatoba Hardwood Decking and Siding](https://www.mataverdedecking.com/hubfs/Mataverde-Jatoba-E84-010517.pdf)   --- [![Request A Decking Quote Now](https://no-cache.hubspot.com/cta/default/112655/interactive-158332377170.png) ](https://www.mataverdedecking.com/hs/cta/wi/redirect?encryptedPayload=AVxigLJS38K5L6kiJsP5n0rga8jx3kcL1eK%2FX%2FcB1zHh5Q6dz6j3xk79x4iuS8KO0PvsczzBwapHxpNXPtY6BDYVyBGUld5BHPrEB9YnOwZuL9n5ZM62IooyZlM6LxyeFeKhxwn00oBtdURyY%2BcibSUfLrIj1sX4yRBVzragvaWFa3qQvrcGLY9pXVEfM3kbYyWzaOQMWlskXbYkgnBZ3lLNJsJx6qBEabU%3D&webInteractiveContentId=158332377170&portalId=112655) --- ## MATAVERDE HARDWOOD DECKING SPECIES RECEIVE WUI LISTING **Several Mataverde Premium Hardwood decking species received a Class A "WUI" Listing from the state of California.** The Office of the State Fire Marshall in California has listed Mataverde Premium Hardwood decking species Ipe, Cumaru and Machiche for compliance with W.U.I requirements.
