What is Thermowood Decking?
 
 
  
Creating thermally modified wood is a natural process, revolutionized in Scandinavia decades ago.  Mataverde Thermowood is beautiful wood - recommended by many of the world's leading architects.  Thermally modified wood technology is an environmentally friendly process, requiring no chemicals or toxins. Using only heat and water, the wood cell walls are permanently modified for the better.

What's so Special about ThermoWood Decking?

The ThermoWood thermal modification process alters the properties of the wood permanently.  The process starts with sustainably harvested domestic hardwoods. 
 
ThermoWood properties 
The results are stunning, from both an aesthetic and performance standpoint.  The thermally modified wood is darker and richer appearing, similar in appearance to Ipe or other tropical hardwoods. The mechanical properties of the wood are changed too; most of the sugars are 'cooked' out of the wood, improving its rot-resistance to protect against decay and fungus. The wood is far more stable, too.  Normal expansion and contraction  happens seasonally with all outdoor woods. With Mataverde novathermowood decking, the expansion and contraction is minimized.
 
The result is a better looking, higher performing, durable exterior thermally modified wood decking material, unlike any other.
 
  • More durable decking - The sugars are transformed during the thermal modification process. Thermally modified wood is more resistant to mold, fungus and spores, and far less likely to rot and decay than the original wood. 
  • More dimensionally stable decking - by drying the wood out fully, then adding moisture back in, thermally modified decking wood is far less prone to seasonal expansion and contraction than traditional hardwood decking.

 

 

 

Color and Graining of Mataverde ThermoWood Decking

The Thermowood thermal modification process gives the wood a rich, dark brown color. If the "new wood look" is your goal, Mataverde Thermowood decking may be finished with various sealers and maintained periodically as needed.  Oil based sealers, such as Penofin or others, work best to protect your investment.

Or, if you prefer a more natural 'weathered wood' appearance, Mataverde Thermowood decking can be left untouched and will gradually age to a lustrous silvery gray patina over time, for a low maintenance, real wood deck.

Mataverde® ThermoWood Appearance Options

 

Thermowood aging processWhat will ThermoWood look like as it ages? Thermowood is well known for its beauty, dimensional stability and durability. But ultimately, Thermowood is still a natural wood product, and all exterior woods will age differently once they are exposed to outdoor weather conditions.

There are appearance and maintenance options to choose from. Learn more about the appearance options and life-cycle performance of Mataverde ThermoWood. here is the typical process:

  •  Initial appearance of Thermowood is a chocolaty brown color
  • A coat of oil finish will darken the color tone to a rich dark brown color
  • As the oils weather and the wood ages, the color will start to lighten to softer brown tones
  • At this point, you may either refinish to a darker brown appearance, or
  • Allow the wood to weather out to a silvery gray patina for a low maintenance decking option

Mataverde® ThermoWood Physical Characteristics 

and Mechanical Properties

What is thermal modification? How does the thermally modified wood process work?  The ThermoWood process produces the highest quality thermally modified wood. Check out the video below to find out more.


Mataverde® ThermoWood Decking has exceptional dimensional stability. ThermoWood exhibits only minor movement after it is milled and installed. An initial oil finish, before installation, helps minimize any shrinkage and checking during its initial acclimation and on-site seasoning. Thermowood is an excellent decking material option to consider if you'd like a sustainable and all natural real wood deck surface for your project. 

 

STABILITY ThermoWood decking is exceptionally dimensionally stable, and exhibits very limited expansion and contraction, especially compared to other woods. An oil based finish improves the stability further and helps minimize surface checking and splitting.
DURABILITY Because the ThermoWood process 'caramelizes' the sugars in the wood, ThermoWood is exceptionally resistant to fungi, decay and rot.  With normal care and maintenance, ThermoWood has a service life of 25 years or longer, depending on conditions.
HARDNESS Thermowood Ash has a Brinell hardness of 30.5 N/mm2
FIBER BENDING STRENGTH Thermowood Ash has bending strength of approximately 12,000 psi, (roughly 20% less than non-modified Ash.) 
DENSITY ThermoWood Ash has a density of approximately .62 g/cm3. It is much lighter in weight than high-density tropical hardwoods, like Ipe. Yet it is still very resistant to decay. Win/win.

Deck Installation Tips and Techniques

 

Mataverde thermowood decking can be installed by a number of standard deck construction methods including, face screw, specified hidden fasteners and Eurotec rooftop deck system components. Because of its strength and hardness, Mataverde Thermowood decking can be installed with very similar methods to those used for other hardwood decking species.

 

FACE SCREW DECKING INSTALLATION METHOD

Thermowood face screw decking installationThe most secure and best way to install Mataverde thermowood wood decking is with face screws. If you choose to install your thermally modified wood with face screws, take care to maintain a minimum of 3/4" to 1" distance of screws from the edges and ends of boards for best results.  Stainless steel screws last longer and work best.

Thermowood decking is harder than the original wood. The only real downside of installing thermally modified wood decking is that it is slightly more brittle than the original wood. So, this fastening method will minimize the potential for splits and will hold up very well throughout the lifetime of your Mataverde Thermowood deck.

HIDDEN FASTENER DECKING INSTALLATION METHOD

Using hidden fasteners is a great way to get a clear looking surface on your thermally modified decking.  Pre-grooved decking works great for this type of installation and the Mataverde hidden deck fastener works well with pre-grooved decking.

Mataverde Thermowood Decking Care & Maintenance

 

Mataverde novathermowood decking is a low maintenance real wood decking material. As a result of thermowood technology, Mataverde Thermowood looks and acts much like other hardwood decking materials. Mataverde Thermowood is non-toxic and safe to the environment as well as humans.

Mataverde thermowood requires no maintenance beyond normal cleaning. Thermowood decking is easy to care for and there are appearance options, including oil finishes and a low maintenance option, where you can allow your deck to weather to a gray driftwood look.
