Information about Kiln Drying
IS IT IMPORTANT?
a doubt, kiln-drying is the most important step in the manufacturing
of a log home. This critical process of reducing a log's moisture
content ensures a quality product that will last over time. When
administered properly, kiln-drying will not only remove excess
moisture from the wood, it eliminates mold and fungi and provides
a better base for stains and finishes. At Old Timer Log Homes,
we understand the importance of kiln-drying and take great care
to ensure the process is properly adminis- tered. With three kilns
in operation, Old Timer dries its logs for a minimum of 30 days
at temperatures that rise to 180 degrees, uniformly shrinking,
sanitizing and stabilizing the logs. This period of time ensures
that each log's moisture content has been reduced to 19% or less.
This results in the removal of as much as 10,000 lbs. of water
from a typical log home. Old Timer Log Homes is committed to manufacturing
only strong, quality homes, and it is our goal to provide customers
with the very best product available. Based on our knowledge and
over 25 years of experience in the log home industry, we feel
that we cannot provide the very best product without kiln-drying.

- Logs are
monitored throughout the drying process according to our kiln-drying
- When criteria
has been met the logs are checked
- A section
of the log is cut and weighed.
- A moisture
meter (probe) is used to check moisture content
- When the
moisture level is achieved, the logs are ready to be milled
- Logs are
monitored during the milling process.
- Any log
not meeting the correct moisture level is dropped out
- To assure
quality, logs are checked a final time before being shipped

log home constructed of 7" solid wood walls might have an indicated
steady-state R-value of R-9. But in most U.S. climates, especially
those where log homes are most popular, a stick framed home would
have to be insulated to about R-13 (or even R- 15 in some areas)
to perform as well for heating and air-conditioning energy used
on an annual basis. This comparison assumes similar attic insulation,
window performance, foundation design and the use of identically
efficient mechanical systems for heating and cooling. In practical
terms log homes may be expected to perform from 2.5% to 15% more
energy efficient when compared to an identical wood frame home,
considering annual purchased heating and cooling energy needs.
