Kiln-Dried Traditional Logs and Timbers

Timberhaven’s Eastern White Pine Kiln-Dried Traditional Solid Logs and Timbers are a single kiln-dried cant. These members are kiln dried to about 19% moisture content then milled into their final shape. The kiln-drying process reduces shrinkage, warping, and twisting while also killing insects and fungi. This is the log and timber choice for traditionalists who prefer the rustic appeal of a log or timber home—one filled with the distinctive character and charm so valued by log and timber frame home purists.

Features and Benefits of Kiln-Dried Traditional Logs and Timbers

Non-Settling System – Kiln-dried traditional solid logs and timbers are “pre-shrunk” before milling, providing a stable, uniform building material that will not settle after construction. These logs and timbers are kiln-dried certified to 19% or less.
Structural Stability – Severe shrinking, warping, and twisting are minimized because drying occurs in the kiln before milling and construction, not after your home is built.
Certified Quality – Every log and timber is graded and stamped with the Log & Timber Homes Council Certification for Stress Grades. Defective pieces are removed by trained inspectors, ensuring only the highest-quality logs and timbers are used in your home.
Sanitized for Protection – The high heat of kiln-drying kills wood-decaying properties of mold and fungi plus insects (including eggs and larvae), creating a healthier and more durable building material.
Reduced Pitch Seepage – Pitch is crystallized during the kiln-drying process, minimizing sticky seepage of your logs and timbers.
Ready for Finishes – Stains and protective finishes can be applied immediately after construction. Applications absorb deeper, last longer, and protect your home right away.
Lightweight Handling – With thousands of pounds of excess water removed, kiln-dried log and timbers are lighter and easier to handle. Even the longest beams can typically be maneuvered by two people.
Authentic Beauty – Each traditional solid log and timber retains its natural grain and character, creating a warm, rustic aesthetic that is truly one-of-a-kind.
Proven & Time-Tested – Traditional solid logs and timbers have been relied on for centuries in log and timber construction, offering unmatched durability and timeless appeal.
Energy Efficiency – Traditional solid logs and timbers provide excellent natural insulation and thermal mass, helping regulate indoor temperatures and lower energy costs.

Why does Timberhaven kiln-dry its products?

After decades of collective experience in the wood products business, we have found compelling evidence that kiln-dried log and timber products provide the most stable, troublefree building material. Over the years, we have collaborated with leading independent researchers – including Penn State University’s Dept. of Forestry, Montana University’s Wood Science Associates, and PFS Corporation – who agree and help us continually refine our technologies.

How does the process work and the final moisture content determined?

The process begins by placing a large stack of dimensional lumber (cants or 2x laminate plies) in a sealed building and slowly raising the temperature to 170 degrees Fahrenheit. Large fans maintain a consistent drying rate, and moist air is removed with dehumidifiers. The drying rate is carefully monitored, as the outside perimeters of lumber tend to dry faster than the centers. Uncorrected, this imbalance may cause severe checking (cracking). The final moisture content is measured in accordance to grading rules set forth by the Log and Timber Homes Council. After the 2x laminate plies (average 9 percent moisture content) or the solid cants (average 19 percent moisture content) are properly dried, they are ready for milling. The moisture content of our log and timber products is guaranteed in writing.

The Experts Speak Out: KILN-DRIED VS. AIR-DRIED

Kiln-Dried Log & Timber products— engineered or traditional solid —provide the best building materials possible, and this approach is backed by independent experts in the wood technology industry.

Air-drying large timbers usually takes longer than a year to achieve moisture content levels that are reasonably acceptable for construction. Proper kiln-drying provides much more predictable, controllable results.

~Dr. Paul Smith Professor of Forest Products Marketing Penn State University

The recommended moisture content of wood should be matched as closely as is practical to the equilibrium moisture content (EMC) conditions in service.

~USDA, Forest Service Forest Products Laboratory

Proper kiln-drying procedures control the drying environment and reduce the amount of severity of drying induced defects. Drying wood prior to installation provides an opportunity for the wood to maintain relatively stable dimensions during service.

~Paul Blankenhorn, Ph.D. Professor of Wood Technology Penn State University

There are two important differences between Air-Dried and Kiln-Dried. In a kiln, the wood is usually heated above 130F, which kills all insects, eggs, and fungi. Second, with resinous softwoods, the heat drives off the resin that would be liquid and runny at room temperature.

PLEASE, do your research!

More and more log and timber frame home manufacturers claim to kiln-dry their logs and timbers, but unfortunately there are no industry standards. Some companies’ logs or timbers spend only a few days in the kiln; our controlled process requires more than 30 days. There are huge differences in the logs and timbers that kiln-dried manufacturers supply, so qualify the companies you are considering by asking these questions:

How are the logs and timbers dried?
What temperature levels are achieved in the kiln?
To what moisture content are the logs and timbers dried, and is the moisture content guaranteed in writing?
How is the moisture content measured?
Do your homes require a settling system?

Vacation Every Weekend

What initially drew me to Timberhaven Log & Timber Homes was their engineered (or laminated) logs. They’re essentially white pine boards that are laminated together then milled into whatever shape you want. Now, the minute I get to my new log home, my blood pressure drops. It’s like we’re on vacation every weekend.
