| The cross section of a typical log. |
The sapwood section of the log, or soft layers between the heartwood
and the bark is typically eliminated during the squaring process. This assures
that settlement of the logs will be minimal -- not exceeding one inch in an
eight-foot wall height.
Log homes built using hand-crafted round logs can be very
attractive. However, if you are looking
for your log home to be efficient, properly weather-sealed and free of
excessive settlement and maintenance problems, a squared log is certainly
recommended.
Another important factor in the building of a
solid, stable log home is the size of the logs used. The preferred best practice
is to use full-dimensional logs to. This means, for example, that an 8"x
12" log actually measures 8”x 12", as opposed to 7 1/4" x 11
1/4" which can be found in use by some inferior log home manufacturers and
builders. Using a full-dimensional log
adds thermal mass, which translates into improved insulative capabilities,
higher energy efficiency and ultimately long-term cost savings. All of these positives certainly trump any
short-term cost savings realized in purchasing smaller/thinner logs. Be sure to choose a log home manufacturer who focuses as much on quality as they do on price. After all, this will presumably be a long-term investment and you want it to last.
A third and final consideration is the corner
styles to be used in the building of your log home. Generally available varieties include
dovetail (or sculptured dovetail), saddlenotch (or sculptured saddlenotch) and
post corner systems. Each of these corner styles have their aesthetic and
functional differences.
Dovetail corners
have unique water-shedding capabilities as all angles lead out of the corners
so water will never have a place to collect in the joint.
Saddlenotch corners with interlocking logs
create a very traditional log home look while adding structural strength.
Penta-post cornering systems can be used to create irregular angles and unique log home designs without compromising the integrity of the structure.
So log sizes and shapes certainly can and
will figure into the look, feel and long cost-effective life of your new log
home. Consult carefully with your log home builder and/or the manufacturer to ensure you are getting the right combination of design, stability and value.
