Mataverde Thermally Modified Hem Fir siding is an exceptional real wood siding option that can be used in a traditional siding profile or as rainscreen cladding material.  The unique thermal modification process for this softwood species employs a vacuum kiln and uses steam.  Together, the steam and the pressure allows Hem-Fir (Hemlock) to be thermally modified at lower temperatures, producing spectacular results. 

The finished product, Mataverde ThermaWood Hem Fir, is exceptionally stable, very durable and outperforms the original in many measurable ways. Because Mataverde ThermaWood Hem Fir uses the upper grades of Western Hemlock ("A+ better" and "C+ Better" grades) and vertical grain boards, the product not only performs better but is absolutely beautiful as well. Mataverde Thermally modified Hem Fir has the great looks you would expect to find in Western Red Cedar.

Care and Maintenance of Mataverde ThermaWood Cladding

Mataverde thermally modified Hemlock wood siding is a low maintenance, real wood cladding material. As a result of the thermawood technology using a pressurized vacuum kiln, Mataverde Thermawood Hem Fir looks and acts much like hardwood siding materials. Mataverde Thermawood Hem Fir is sustainably harvested, non-toxic and safe to the environment and humans.


 Mataverde thermally modified hemlock siding requires no maintenance beyond normal cleaning. Thermally modified cladding 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.

Thermally modified siding is real wood, but it performs so well, it can be finished or allowed to weather. Thermawood rainscreen wood siding has a rich natural brown beauty that can be enhanced with a natural oil finish (like Penofin) or it can be allowed to "weather out" to a natural silvery patina. 

Whether you prefer to maintain the 'like new' wood look, or the silvery look, the choice is yours.  For more information about your finish options, DOWNLOAD "HOW WOODS WEATHER GUIDE"
