Log Wall Characteristics
Looking
at all the beautiful full-color glossy photos of log
home in magazines gives us an idealized vision of the
perfect wooden house. Like a supermodel, we can't
imagine wrinkles and imperfections, but like any natural
product, log walls are full of traits that are an
integral part of their character.
CHECKING: The new visitor to any log home is
invariably struck by the cracks in the logs, sometimes
stretching for several feet. Initially they might look
alarming, but these cracks, or checks, are a natural
process that occurs over the first few years when logs
are still drying and reaching equilibrium with the
environment. In no way do they weaken the integrity of
your log wall.
When trees are cut down, there is naturally still some
moisture left in the cells, especially when the tree is
cut down live. These logs are called "green" and will
settle many inches if used right away to build a house.
Some manufacturers let their logs dry naturally – air
dried – while others put the logs in a kiln and bake
them for 30-45 days, which removes 80-85% of the
moisture. However, they can't go any farther without
doing damage to the wood, so the logs dry naturally for
the next few years, and this process can create checks
in the wood to relieve the pressure. However, the
heartwood closest to the center of the tree is so hard
that the checks will not go beyond the center of the
log. As a result, you will not see the checks go all the
way through.
SETTLING: As you may already suspect, there is a
relationship between moisture content and settling of
your log walls. No, settling does not have to be a
"dirty word". As long as your builder knows how to deal
with the settling and make provisions for the windows,
doors, plumbing, and interior walls, your house can
settle many inches and still age comfortably. Any log
home will come with about a 2" gap above all the doors
and windows, which will need to be filled with
insulation. The builder will cut a vertical groove in
the frame and affix nails to the windows and doors that
will slide down the groove as the building settles, so
nothing gets crushed. Most kiln-dried homes will only
settle a couple of inches overall, and much of that will
occur during the construction phase.
KNOTS: Depending on the species of wood used in
your log home, some logs have more knots than others,
just as some trees have more limbs than others. The more
interesting the knot, the more likely your builder will
place it at eye level, since each knot is truly unique.
However, don't be surprised if the knots ooze sap on the
sunny exterior walls of your house. Even the sealant
won't stop the sap from working its way out. This will
not happen on the inside of the house, or on the shady
side. It only happens when the sun is beating down on
the logs and heating them up in the summer time.
HAND-PEELED or MILLED: (or anything in between).
Hand-crafted log homes are just that: the logs are cut
and peeled by hand with a draw-knife, which creates a
uneven surface along the log. For an even more rustic
look, some of the bark is left intact. If the log is
milled, the machine takes off the layer of bark, leaving
a fairly smooth surface to the log. This can be sanded
to a fine finish, if you have enough time or money.
Sometimes, the manufacturer might take that milled log
and run a draw-knife across it to make it look peeled.
The type of finish is totally up to the buyer.
CHINKING vs. CAULKING: Chinking is historically
done to a hand-crafted log home in order to keep the
wind from howling in between the logs. It looks like a
broad white band between log courses. When cut by hand,
logs can be scribed so that an upper log is shaped to
match the contours of the log beneath it. However, not
all logs are scribed; some just rest atop the log below,
creating large gaps in the uneven surface. Either way,
handcrafted log homes tend to be chinked, which was
historically a mix of clay, sand, lime, mud, thatch, you
name it, but is now an acrylic compound which expands
and contracts with the wood. Some homes still
require chinking, and others use chinking for
aesthetic purposes.
Many milled log homes are actually caulked with an
acrylic product designed for log homes. This comes out
of a caulking gun, and creates a neat, finished look as
well as protecting the seams from infiltration. We tend
to caulk milled homes or do nothing at all between log
courses, because the joinery system is so tight that
this step is not mandatory.
Every log home is unique, and each has its own
personality. It's amazing how many different
construction systems are available to create homes out
of logs, and every style has its own characteristics.
But overall, no matter what your log home looks like,
the cozy warmth of logs cannot be duplicated in any
other kind of house.
