Kiln Dried Vs. Engineered Wood

Kiln-dried hardwood is typically considered top-of-the-line, and has been a long-standing selection in durable sofas. The better and most reputable suppliers of seasoned logs allow their logs up to 2-3 years to dry out, however as this takes up so much space, very few do this and finding seasoned logs that are low in moisture are extremely hard to find, with the British climate making it difficult to achieve the very low moisture contents that kiln drying can achieve.

I think the single biggest help would simply be to know what the MC the wood is currently at. Beyond this, as a general rule, I’d recommend starting outdoors and moving indoors after several months — it all depends on what the MC of the wood is at. Tarps aren’t ideal, but yeah, you should try to keep it somewhat protected from the elements — direct sunlight as much as rain.

The natural air-drying of lumber can be a long process, so oftentimes lumber will be kiln-dried to speed the process -drying is basically a process of placing sawn lumber into kilns where heated air is circulated and the temperature and RH of the kiln is controlled for the purpose of reaching the wood’s equilibrium moisture content (EMC): a balance between the MC of the wood, and the RH of its surrounding environment, depending upon the end wood products application specifications.

The main advantage of a kiln is that with the increased temperature and airflow—all while carefully maintaining and controlling the ambient humidity—the wood can be dried much more evenly, minimizing any sort of moisture gradient between the outer shell (which dries very quickly) and the inner core (which slowly equalizes moisture with the shell).

Our 1.25m flexi pallet contains kiln dried un-split hardwood logs that are dried to an average moisture content of 20% or less and are ready for burning straight-away on any wood burning crate equates to 1.72 cubic meters of loose volume logs and if we compare our crates with the bulk bags available in the market, then this crate equates to at least 2 big bags.

The traditional way of buying firewood operates like this – a tree surgeon or farmer would fell trees, cut, split and stack them using air to naturally season and extract the moisture out of the logs over a prolonged period, often a year, after which it was considered suitable for burning on fires and in stoves, and by suitable I mean by using lots of kindling a fire could be started and kept going, albeit with a lot of effort and certainly not efficient in regard to the heat output.what is kiln dried wood

I have had success taking wood down to 6% in mere minutes by microwaving very small pieces of oak in the kitchen microwave a few pieces at a time (a lot of trial and error getting the timing/settings just right for my wattage of oven of course the microwave heats the water on the inside and you then set the wood outside the oven to dry while you heat the next batch; test and repeat until you get it).

A wood moisture meter is crucial in establishing and maintaining healthy wood MC levels at each stage of lumber production.A wood moisture meter is a tool which measures the wood’s MC. As green wood circulates for processing in a mill, in-kiln and in-line MC systems measure and document the wood’s MC and track the efficiency of the kiln-drying process.

The way to determine water content is usually by jamming an electronic probe into the side of the board on an inconspicuous surface, but if you know how much your wood should weigh dry versus wet then you can determine water content by weighing it. I suppose that tip is more useful for people using very small pieces of wood who don’t want any surface marred by test probes.

As long as the RH is low enough, the air will continue to dry all exposed surfaces of the wood. Freshly cut wood contains up to 60% water whereas the kiln drying process reduces the moisture content to less than 20%, which will enhance your log fire experience. Proper stacking of the lumber is necessary to achieve optimum drying conditions for any species in any situation. Be sure the studs on the side walls frame openings for doors at least as large as the end dimensions of the wood pile.

All our standard seasoned wood is split into good size logs and air seasoned until there is no more than 25% moisture content. In the mid 1990s a formal audit of industry needs identified the need for a comprehensive training program to provide professionals involved in kiln drying with the skills needed to ensure optimal value and volume recovery from the drying process. Fiber saturation point for most wood species occurs at moisture contents of about 25 to 30%.

Since wood smoke is fuel, we want to burn it as completely as possible and that means mixing with adequate oxygen in the combustion air. However, in some cases, such as when processing logs or other green wood into lumber, a more meticulous procedure will need to be followed. Wood is divided, according to its botanical origin, into two kinds: softwoods, from coniferous trees, and hardwoods, from broad-leaved trees. Most softwood lumber kilns are track types in which lumber packages are loaded on kiln/track cars for loading the kiln.

Kiln dried logs come and see us and inspect the logs dried in our warehouse under genital heat for 12 months you wont find a better solid fuel. If you’re still unsure or have other questions feel free to contact your local Dunn Lumber , or leave a comment below and I’ll get back to you ASAP. One thing you will always find with kiln dried logs, unlike really well seasoned logs, is that there will be more of a gradient in moisture content across the log.

Now there’s a cost-effective, reliable wood moisture meter to suit any wood measurement application goal, from the home to the lumber producing mills. Thicker lumber exposed to the same drying conditions will take longer to reach its EMC than thinner lumber. This occurs naturally, and it occurs throughout a wood product’s lifespan even after it has been harvested and kiln-dried for human use.

Our wood also has a lower rate of carbon emissions following the Northern standards of production, so you can be assured of the best quality. Builders bag of kiln dried logs under 20% moisture these logs are best fuel for any fire or stove. Do not plan to resaw thick dried lumber-saw it to the desired size before drying. On the other hand, I’ve been told kiln dried wood is bad for lathe work, and in fact green wood is best for turning.

Movement of water takes place in these passageways in any direction, longitudinally in the cells, as well as laterally from cell to cell until it reaches the lateral drying surfaces of the wood. In addition to shrinking unevenly or possibly coming loose during drying, (leaving a knothole), knots can also create areas of concentrated abnormalities in the wood grain, and consequently impact its shrinkage properties. This kiln captures the energy needed to dry wood from the water in the wood itself. The kiln floor structure will deteriorate rapidly if resting directly on the ground. Moisture content is the most important factor of any firewood and effects the quality of the output.

Temperature and humidity are carefully controlled during the drying cycle using drying schedules designed for the species, size, and condition of the wood. The high heat used in the kiln-drying process sanitizes the logs killing mold and fungi (which cause wood decay), as well as insects, their eggs and larvae. There is no officially determined width of juvenile wood, (usually excluding the first few central growth rings is sufficient), but generally, the further the wood is cut from the pith, the better.
