ThermaWood Traditional Wood Siding Options
Thermally Modified Hem Fir Siding Options
Mataverde Thermally Modified Hem Fir Siding is available in many traditional wood siding profiles.
Mataverde ThermaWood Hem Fir siding is a beautiful and high-performance exceptional real wood siding option that can be used in traditional tongue and groove siding profiles. The material is produced in a specialized vacuum kiln using steam, pressure and low temperatures. Together, the steam and the pressure allows Hem-Fir (Hemlock) to be thermally modified at lower temperatures, producing a unique wood product with high performance and exceptional beauty.

The finished product, Mataverde ThermaWood Hem Fir, is very stable, highly durable and outperforms the original Hemlock wood in many ways. Mataverde ThermaWood Hem Fir uses the upper grades of Hem Fir - "A&BTR" and "C&BTR" Vertical Grain for siding 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.
Mataverde ThermaWood thermally modified Hem Fir siding
Mataverde ThermaWood is manufactured by heating the wood to a temperature of 160º C (320º F) while it is protected with steam, under pressure. Besides providing protection, the pressurized steam also affects the chemical changes taking place in the wood. As a result of the carefully controlled thermal modification process, Mataverde ThermaWood is created. Its color darkens, it is far more stable than normal wood in conditions of changing humidity, and its thermal insulation properties are improved.
