THERMAL MODIFICATION SERVICES
Optimizing lumber for a wide array of applications
Benefits of Thermal Modification
Unparalleled Dimensional Stability
By removing moisture from wood cells, thermal modification helps the wood retain its shape even when exposed to moisture. This results in improved dimensional stability, reducing the risk of warping or distortion.
Increased Resistant to Decay
One of the significant benefits of thermal modification is the reduction of sugars in the wood, which are typically targeted by decaying organisms and termites. This process makes the wood less attractive to these pests, thereby increasing its resistance to decay.
Lengthens Lifespan
While the exact lifespan can vary based on the wood species and application, thermal modification generally extends the life of wood products. A typical estimate is around 25 years, showcasing the durability and longevity of modified wood.
Less Susceptible to Warping & Cracking with Changes in Humidity
Thermal modification also aids in making wood less susceptible to warping and cracking when exposed to changes in humidity. The stabilized cellular structure resulting from this process contributes to the wood's resistance to such issues.
Improved Heat & Sound Insulation
Another advantage of using thermally modified wood is its enhanced heat and sound insulation properties. This can be particularly beneficial when considering applications such as paneling for rooms like music studios, where both aesthetics and functionality are crucial.
Sustainable & Chemical Free
Thermal modification is an environmentally friendly process that does not involve the use of chemicals. By using only heat and vacuum, this method ensures that the wood remains chemical-free. Additionally, sourcing wood from ethical suppliers like the Makah Tribe further enhances the sustainability aspect of our product.
What should thermally modified wood be used for?
Our thermal modification process significantly increases decay resistance and dimensional stability, adding value to outdoor projects siding, decking, docks, cladding, and outdoor furniture. But it is versatile and can be used for a variety of applications like musical instruments, standup paddleboards, and saunas. However, it is important to know that thermally modified wood is not recommended for structural applications. It’s use is not limited to the great outdoors, it can be used in residential and commercial settings like windows, doors, bathrooms, paneling, and interior flooring.
The benefits of thermally modification has caught the attention of architects, designers, contractors and fine craftsmen alike. It is a sustainable alternative to tropical hardwood species, composite lumber, and chemically treated wood.
How is thermally modified lumber made?
At our cutting-edge facility in Port Angeles, Washington, we employ the innovative Maspell kiln from Italy to conduct the Thermal Modification process on lumber. This advanced technique involves subjecting the lumber to heat and vacuum, all within a vacuum-sealed environment that eliminates any risk of fire.
Throughout this precise procedure, temperatures gradually escalate until reaching a peak of 400 F before entering a gradual cooling phase, a transformation spanning three days. Its color deepens to a rich chocolate brown hue, a visual testament to its enhanced durability.
Within the core of the lumber, a profound metamorphosis takes place, transcending mere surface alterations. Sugars and starches harmonize into a protective caramelized shield, fortifying the lumber against termites and other invasive pests. Concurrently, the cellular structure undergoes a strengthening process, enhancing its water resistance.
