What Does ThermaWood FR Look Like?

ThermaWood FR Hem Fir has the great looks of what you'd expect to see with the upper grades of Western Red Cedar. ThermaWood FR Hemlock has a clear vertical grain, beautiful natural colors in a lighter range, more consistent color, and absolutely beautiful. ThermaWood FR can be stained with many oil based exterior stains to meet your project design scheme.

Check out the video below, where ThermaWood FR was used on the exterior and interior of a new home that was rebuilt in a wildfire-prone zone.

“I didn't want to adapt [fire retardant treated] siding material. I wanted something that was flush and looked very modern and contemporary."

- Chris Cahill, Cahill Studio Sonoma, California


ThermaWood FR has a color range deepened by the thermal modification process. You can see a typical color range in the photo below.

Why use Mataverde ThermaWood FR?

 

Mataverde ThermaWood FR fire retardant treated lumber with Thermex-FR has many advantages over other treated lumber: 

  • Safe and non toxic formula
  • Environmentally friendly
  • Adds durability to the wood
  • Classified as "ignition resistant"
  • Helps resist the spread of fire, which helps protect your home, property, and family from fire
  • The only product on the market that passes the natural weathering tests for exterior use
  • The fire retardant treatment process works so well outdoors it is covered by a limited lifetime warranty.
 

How Does It Work?

Not all fire treated lumber is equal. Most fire treated wood options use water soluble chemicals. They work fine for slowing down the flames. Most of them work well indoors.

But, because they are water soluble, they don't last very long in an outdoor environment. The fire treatment can literally wash off. Rain, snow and weather eventually rinse away the fire retardant chemicals and the wood becomes non resistant to fire over time.  There is a much better solution.

Mataverde ThermaWood FR Is Different

The safe and nontoxic fire treatment additive is water soluble, too, but only at first. That's how the treatment can be easily pressurized deep into the cells of the wood. But that's where the similarity stops.

After that, the material is kiln dried - again - and the treatment is essentially baked into the wood, permanently. That's why Mataverde FR is covered for fire resistance by the manufacturer's lifetime limited warranty for fire resistance.

While other fire treatment processes for wood may be used in certain areas (mostly indoors) and in limited applications, Mataverde ThermaWoodFR Fire Retardant Treated Lumber can be used widely, under many conditions. Mataverde ThermaWood Fire Retardant Treated Lumber meets a wide range of fire resistance requirements.

ThermaWood FR Fire Treated Decking

ThermaWood  FR Fire Retardant Treated Lumber is available in decking and siding profiles.  The fire retardant treated decking is available in ThermaWood  Hem-Fir. 

ThermaWood  decking is available in 5/4 x 6 nominal size deck boards in C+ Better vertical grain Hem Fir. 

With C+ better grade you can expect vertical grain Hem-Fir boards.  In this more rustic grade of Hem-Fir decking, you will see a fair amount of mineral streaking and some knots are allowed per board. Most of the knots are small and tight. 

If you don't like the appearance of portions of particular boards, the solution is to defect-cut out that portion, and use the remaining pieces in your project.

This Notice is intended to provide general information about the potential application of paints or stains to our wood products pressure infused with proprietary fire retardant resins. 

BEFORE USING ANY PAINT OR STAIN ON OUR FIRE RETARDANT TREATED WOOD PRODUCTS, YOU SHOULD CONSULT WITH A COATINGS EXPERT OR MANUFACTURER TO ASSURE YOURSELF THAT THEIR RECOMMENDED COATING HAS BEEN SUCCESSFULLY TESTED ON THERMEX-FR TREATED PRODUCTS.
