Newly available sustainable thermal modification technology improves woods stability and exterior performance.
Timber Holdings USA is happy to announce it has expanded its offerings of environmentally-responsible products to include Cambia™ by Greenleaf™. The energy-efficient Cambia™ process uses high heat and steam in a controlled atmosphere to improve dimensional stability and decay resistance of lumber and wood products. Currently available in a selection of domestic hardwoods and prefabricated components, Cambia™ hardwoods are most commonly used for siding, decking, lumber and site furniture.
"We are proud to announce our partnership with Cambia by Greenleaf™ and its founding partner, Northland Forest Products, as the companies share Timber Holdings' perspective on sustainability, commitment to environmental stewardship and dedication to maintaining long-term partnerships with sustainable practice organizations," said Brian Lotz, president and CEO of Timber Holdings, USA "The Cambia™ process has the ability to naturally add durability and stability to hard wood species, similar to those already found in our existing Iron Woods® line and will help us to better meet our customers' needs by greatly increasing their options for environmentally-friendly wood species."
A significant percentage of the energy required to thermally transform wood using the Cambia™ process comes from the wood itself, making the process not only energy-efficient, but also environmentally-friendly as no chemicals are used to preserve the wood and no pollutants are emitted to the environment. Through the proprietary process, the thermally-modified wood no longer contains sufficient water or nutrients to support microbial growth, or provides a food source for insect infestation. Additionally, the cellular structure is altered, creating a more stable product that is less susceptible to movement (cupping, warping & twisting). As a bi-product of the thermal process, the wood takes on a dark rich uniform color throughout. Cambia also accepts stains and finishes that have been formulated for non-modified hardwoods. The thermal modification minimizes the difference in early and late wood densities, actually allowing paints and stains to last longer.
"In the same way that all Timber Holdings wood products contain no chemicals or manmade materials, the unique Cambia™ process is also 'Green by Nature,' and is completely natural throughout the entire thermal modification process, resulting in no non biodegradable waste," said Brian Lotz.
The commitment of both partners to natural and sustainable wood products is evident from the Forest Stewardship Council (F.S.C.) Chain of Custody early adoption membership numbers - #' 22 for Northland and #48 for Timber Holdings. These shared attitudes and experiences are now combined to help bring Cambia™ to the forefront of exterior wood product usage in North America.
Cambia™ is currently available in FSC certified red oak, poplar, white ash and soft maple lumber, or prefabricated decking, siding, railings and millwork.
