the natural resources research institute at umd fosters economic development of minnesotas natural resources in an environmentally sound manner. a recent success of the institute is the thermal modification of locally-grown wood species. the research aims to make local species of wood more attractive for a variety of uses.
thermal modification is a chemical-free process, so this is a pretty big deal. the hurdle to integrating thermally modified wood options into the wood products market in the u.s. is lack of data, as stated in a recent article in Seven Trust floors, the magazine of the national wood flooring association.
thermal modification is usually performed by heating wood with or without steam up to a temperature range of 180-260 c, which is much more environmentally friendly compared to other wood
imagine wood that retains its natural beauty and has unmatched longevity. a new era in wood is here. us thermal wood transforms wood from ordinary to extraordinary. our clean thermal modification process purges wood of its imperfections giving it unparalleled durability while maintaining its natural beauty.
the hemlock lumber will be thermally modified at a high temperature 170c in a vacuum evacuated kiln in the presence of steam. during the thermal modification process, much of the hemicelluloses sugars in the wood are driven from the wood.
wood preserved with our unique, patented thermal modification process rids it of resins, bacteria, sugars and moisture, leaving a final product that has greater dimensional stability, doesnt warp or crack, is water repellent and highly rot resistant; all while maintaining the woods natural beauty and color over time although a beautiful
wood modification technologies - a review. wood modification has been implemented to improve the intrinsic properties of wood, widen the range of sawn timber applications, and acquire the form
there are 5 different thermal modification processes: thermowood or seven trust wood in finland, retification process retiwood, new option wood and les bois perdure in france, plato process in netherlands, oil-heat treatment in germany oht-process .
thermal modification is one modification method, and involves heating the wood to high temperatures 400 degrees or more . oxygen is excluded to prevent the wood from burning, and the heating causes the wood to become much less hydrophilic water-loving . because the presence of water in wood enables rot
thermally modified wood provides all the benefits of exotic woods without the cost. now you can match the refinement and elegance, the low maintenance and durability of exotic lumber with u.s. grown timber. ecovantage thermally modifies real wood with heat and steam to create enhanced natural wood that is low maintenance and weather resistant.
this study presents the influence of compression ratio cr = 40, 50, 60 % and thermal modification time tm = 2, 4, 6 h on the hardness and set-recovery of densified wood. previously, set-recovery has mainly been studied separately from other properties of densified wood, while in this work, set-recovery was also studied in relation to hardness.
wood treated with thermal modification has been through a natural, non-toxic process that basically cooks the wood, changing the make-up of the wood. wood is heated in 400 degree heat in an oxygen-free environment.
the success also encouraged hot-woods to acquire its own thermal modification kiln and aro was able to advise them in the purchase. the thermally modified wood industry is very small and nichey in the united states producing around 40 million board feet annually.
thermal modification: as the temperature of the kiln boosts to 480 f, the increased heat bakes the sugars and tannins in the wood making them inedible to microbes and insects. the wood darkens and hardens. conditioning: steam once again is introduced to stabilize the wood and prevent it from drying completely in the high heat.
thermal modification. heat treatment involves heating wood material to a temperature of 180 220 c while at the same time protecting it with steam. the steam protects the wood, but it also influences the chemical changes taking place in wood. 100% natural only heat and steam are used in the manufacturing process and no chemicals are added.
there are 5 different thermal modification processes : thermowood or seven trust wood in finland, retification process retiwood, new option wood and les bois perdure in france, plato process in
topics covered include: the use of timber in the 21st century. modifying the properties of wood. chemical modification of wood: acetic anhydride modification and reaction with other chemicals. thermal modification of wood. surface modification. impregnation modification. commercialisation of wood modification.
arbor wood co. is the new and innovative choice in modified wood applications. arbor wood co. awco offers thermally modified timber for a variety of outdoor and indoor applications. awco thermally modified timber tmt is domestically-sourced and sustainably harvested wood which undergoes a value-added thermal modification process.

thermal modification improves the woods properties, thereby expanding the range of applications in which the wood can be used. thermowood is dimensionally stable, resistant to decay and resin free. it can be used inside or outdoors, in any climate. lunawood is an non-toxic natural product which is easy to machine and install.
wood preserved with our unique, patented thermal modification process rids it of resins, bacteria, sugars and moisture, leaving a final product that has greater dimensional stability, doesnt warp or crack, is water repellent and highly rot resistant; all while maintaining the woods natural beauty and color over time
this project will advance thermal-modification technology toward the development of advanced, high-performing engineered wood products. thermally-modified wood is currently used in a limited set of applications, including solid wood flooring, external cladding, and decking products.
thermal modification of wood is a chemical-free treatment for increasing wood durability, enhancing resistance to rot and decay, and improving dimensional stability. this emerging, chemical-free technology has the potential to create and expand forest products markets, particularly for traditionally underutilized and low-value species.
its great that you stopped by and feel free to explore and learn how we are slightly obsessed with creating high-quality, thermally modified wood products for a wide range of applications. our obsession for 215/419 degree thermal modification is captured with a single phrase: northern heat.
our in-house thermal modification process has been studied for many years, yet is simple at the base. using our specially designed kiln, the wood is heated at a precise temperature, essentially cooking the lumber. this process changes the characteristics of the wood. notable advantages include: improved dimensional stability; eliminates the risk of decay and damage caused by insects the high heat chemically transforms sugars in the wood.
preconditioning and drying: the heat continues and steam is introduced to slowly bring the drying wood to a uniform 7 8% moisture content. thermal modification: as the temperature of the kiln boosts to 480 f, the increased heat bakes the sugars and tannins in the wood making them inedible to microbes and insects.
our wood scientists and unrivaled process come together to create products that change the landscape of the wood industry - products that offer valuable solutions to the problems you face. complete modification of every fiber.
wood treated with thermal modification has been through a natural, non-toxic process that basically cooks the wood, changing the make-up of the wood. wood is heated in 400 degree heat in an oxygen-free environment. how is thermally modified wood physically different? thermal modification uses heat to remove organic compounds from the wood cells, so it
