MATAVERDE THERMA WOOD DECKING
What is Mataverde Therma Wood Decking?
ENERGY EFFICIENT PROCESS: Because the patented Therma Wood autoclave kiln system works under pressure, less energy is used. This means more energy savings and more cost savings to produce a sustainable thermally modified wood decking material for your project.
HIGHER DURABILITY: Traditional thermally modified wood processes create a wood decking material where the Durability is rated as a Class 2 for pine, spruce, hemlock and other softwoods. Durability of wood decking using the Therma Wood process is rated as a Class 1.
BETTER STABILITY: All woods will move (expand and contract) seasonally, based on humidity and moisture content. Especially exterior woods, because they are exposed to more weather elements. Thermally modified woods are FAR more stable than non-modified woods. They expand and contract to a much lower degree. Less movements means better performance.
BETTER PERFORMANCE: The Therma Wood thermal modification process occurs at much lower temperatures due to the use of higher pressure. This unique method minimizes brittleness, minimizes checks and eliminates most of the mechanical degradation of the wood. Because of the scientific process employed, the result is a far better performing thermally modified decking material.
LESS WASTE: Because of the lower splitting, checking and brittleness of Therma Wood thermally modified wood decking product, more decking material is usable. The result on the job site is less decking material defect cutting and less waste, and that means a lower overall job cost, faster.
LONGER LENGTHS: The vacuum kiln used in processing Mataverde Therma Wood Decking can handle boards up to 20' in length. This means longer length thermally modified decking boards are available than with other older thermally modified wood processes.

About Therma Wood Western Hemlock (Hem-Fir) Decking
What is Western Hemlock?
What is Thermally Modified Hemlock Decking?
Thermal modification 'cooks' the sugars out of the woods. This alone makes the wood far more resistant to rot, decay and insects. The Therma Wood thermal modification process goes several steps further; its is thermally modified at lower temperatures - under pressure.
- Therma Wood stays stronger structurally
- Therma Wood is less brittle
- Therma Wood is exceptionally durable (Class 1 Durability)
Mataverde Therma Wood Hemlock Decking is a high-performance thermally modified decking material. The product is well suited for exterior decking, siding and trim. Because less energy is used in the thermal modification process, the cost is lower, yet the quality, and performance, is higher.
Color and Graining of Mataverde Therma Wood Hemlock Decking
Before modification, Hemlock wood is very light toned, nearly whitish, with some light purple tones. Once the Hemlock is thermally modified, the colors are browner and richer. Mataverde Therma Wood Hemlock Decking looks a lot like Western Red Cedar - except without all the color variations you find in modern cedar.
Here's an example of some typical color variations you will see between Western Hemlock and Thermally Modified Western Hemlock. As you can see, the thermal modification creates a nice brown appearance.

Grading for Mataverde Therma Wood Hemlock (Hem-Fir) Decking
Mataverde A Grade Thermally Modified Hemlock is the top grade
With A Grade Hemlock, the top end of the product is selected. Mataverde A grade Hemlock has roughly 85% vertical grain and vertical grain appearance boards. May include some flat grain and mixed grain boards. Knots are minimal and limited to one side of the board only. There is limited mineral streaking. Mineral streaking is not a defect, it is a part of the characteristics of this species.

Mataverde C+ Better Thermally Modified Hemlock is the next best grade
The second best grade available in C+ Better Grading. In this grade you can expect mostly mixed grain and flat sawn Hemlock boards. In this more rustic grade of Hemlock or 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.

*Pro Tip - Always plan on ordering extra decking to cover your material needs for defect-cutting and trimming your decking boards. This will allow you to use the best boards and the best portions of each decking board to meet you or your clients' needs and expectations. Any extra materials may be saved on site as 'attic stock'. Keeping a small amount of attic stock is a great insurance policy in case they are ever needed in the future.
