Application
of German and Canadian technologies of "curtaining external corners"
for reduction of gaps between logs after shrinkage of house or a
bath
Appearance is sometimes
deceptive. It concerns to manufacturing techniques of wooden
homes and bathhouses made of a round log.
Let's look narrowly at
appearance of a log house directly after construction. We will look
at the house from side. Pay attention to size of gaps between logs
on internal part of walls (i.e. between corners) and on corners.
Gaps are minimum - all looks perfectly. But we will not hurry up,
we will wait 3-4 years. For this term house will shrink at the expense
of shrinkage of logs (5-10 % from diameter of logs).
| Let's
look what will turn out as a result. If house had identical
shrinkage on external corners of the house and on internal walls,
all would be remarkable - gaps everywhere would remain insignificant
and your house would stay warm and beautiful.
But here features
of wooden house construction come into force (about which,
unfortunately, many building companies do not know). Masters
of "Log Russia" have a long-term experience
of building of wooden houses, and not only for Russia, but
also for Norway, Germany, Spain and other countries of Western
Europe. We always try to study new, to adopt useful experience,
to introduce it, receiving gratitude of our Customers. So
was and with this technique transferred to us by our German
colleagues.

So what will occur with
our house in some years? Nuance is that logs in external corners
always have the bigger humidity, than a material of the basic (central)
part of a wall thereof shrinkage of external corners will be smaller.
And as so, "hovering of logs" will happen in the central
part (they will lean against corners) that will inevitably lead
to cracks, especially on internal surfaces of walls.
For elimination of consequences
of this problem the large quantity of hermetics and pastes is issued
in the world. Pay attention to the following photos (it is a photo
by Perma-Chink). Would you like to close up seams in your house
for the rest of the life? If no, it is necessary to pay attention
to an offered technique. Certainly, it will not solve all problems
with shrinkage, but will essentially reduce them.
The German (it is an
element of Canadian) technology of building of houses is represented
here. Pay your attention to drawing 1. On external corners
the additional gap between logs about 5-8 mm is left. We
will notice that for internal parts of walls this gap should
not exceed 2 mm.
Owing to the deformation
of logs caused by non-uniform shrinkage of logs on corners and in
the central parts of walls, the definitive gap on all length of
a log will be uniform and minimum (fig. 2).

As it looks in
practice is shown in drawings 3...6. Pay attention to gaps
between logs in corners of house.
By the way, in
drawing 3 the hand of the master of "Log Russia",
putting a line of the future groove by means of the special
tool - "line" is shown.

Let you not be confused
with a shade of logs on fig. 5 and 6, these photos are made in winter
in cloudy weather.
We hope, that the received
knowledge will help you to order and construct the House, worthy
you and which would not disappoint you not only now, but also in
the future.
The material of this
section is very close with sections of "undercut"
and "features of shrinkage of
walls made of an oval-flatten" and if you are not familiar
with them yet, we advise You to read them.
