is the oval-flatten? Features of use of gaps at building from an
oval-flatten (the Norwegian notch)
the story about technological features of houses made of an
oval-flatten (a semioval log), probably it will be better
to tell to visitors of our site what is actually an "oval-flatten".
semioval log (fig. 1), has come to us from Scandinavian countries,
first of all from Norway. The freedom-loving Vikings living
at coasts blown by sea winds, were good judges of warm wooden
There is a mistake,
that houses from an oval-flatten are colder, than houses from
a round log, it is not so. A thickness of walls about 20 cm,
very warm notches (by the way, notches
and dowels conduct
their history from the Norwegian lock) provide comfortable
habitation at northern latitudes.
For the sake of
justice, it is necessary to add, that Norwegians historically
paint their log houses with special solutions (traditionally
dark colors), providing safety of wood from environment influence.
After all, if you
pay attention to fig. 1, in an oval-flatten the firmest external
layer of a tree is taken away and softer wood is exposed to
contact with atmosphere. Nevertheless, existing antiseptics
can reliably save your walls, having left to your look all
texture of a tree.
a photo on the right, fig. 2 (these images were taken from
the Internet) is shown a kind of dwelling of Vikings. On a
roof, under a snow layer, the grassy cover, pleasantly turning
green in the summer, is hidden. On the bottom photo (an internal
wall of the house) cracks and gaps arising on flat parts of
an oval-flatten are shown.
In general, oval-flatten
is a whole philosophy. We do not speak about Norwegians who
traditionally cover roofs with a layer of earth with landed
grass (so-called earthen roofs, very warm, but demanding a
We speak about
us. If you are delighted by cracks and gaps of structure of
wood on your walls (they never go through the log and do not
reduce a heat-shielding of walls), forming beautiful drawings
which You can admire, sitting in the cold winter evening at
a fireplace, then you will be necessarily attracted with the
log house made of an oval-flatten.
The following two drawings
(fig. 3 and 4) show how houses from an oval-flatten made by the
company "Log Russia" look. As you can see, the oval-flatten
creates visual lightness of a design of a log shell.
Besides there are some
more advantages of walls made of an oval-flatten:
- The increase in effective area of premises as you have a flat
wall, only 20 cm in thickness. For a round log thickness of a wall
will fluctuate from 24пїЅ28 cm to 40пїЅ50 cm, depending on thickness
of the material ordered by you;
- Convenience of a lining of electro conducting, water-and gas supply;
- Convenience at placing of wall cases, for example, on kitchen
or in a bathroom;
- Very dense and warm notch, especially in compare with a notch
for a round log
- Lower cost of the house of an oval-flatten (considering absence
of notches for windows and doors).
To lacks as already it
was mentioned above, it is necessary to carry:
- Removal of the strongest external layer of wood;
- Presence of cracks and gaps of structure of wood on lateral surfaces
(on a round log, at observance of correct technology, visible gaps
will not exist, and there will be only a small cobweb of cracks).
Now, when you have already
received representation about features of the houses made on the
Norwegian technology, has come the time to tell in details about
nicety of building of walls from an oval-flatten.
We hope, that you have
already familiarized with technologies applied by us about a round
log: "curtaining of external
corners", undercut formation,
creation of unloading cuts etc.
pay attention to the differences, concerning an oval-flatten:
- Proceeding from features
of behavior of an oval-flatten at shrinkage (fig. 5), consisting
in primary formation of cracks on lateral surfaces, necessity for
the organization of curtaining of external corners disappears, as
there is a self-jamming of gaps between logs;
- The undercut in invisible
places, on the contrary, should necessarily be organized;
- Vertical unloading
saw cuts in the top parts of logs also should be organized, nevertheless,
they do not protect a log from formation of cracks on lateral surfaces,
and only promote restriction of their sizes;
- The Norwegian technology
of felling of handcrafted log homes assumes use of notches and dowels;
- Notching of apertures
under platbands in door and window apertures is not required.
In summary, we
will consider walls made of an oval-flatten more close.
In drawing 6
the wall with cuts is shown, pay attention to the second
log from above - already on a building site there were cracks
along a log. Let it does not frighten you, this is a feature
of an oval-flatten.
On fig. 7 the
close up of cut is shown, note, please, characteristic notches
near "bowls", their appointment is similar to
notches in bowls for the Canadian cabin technology.
On fig. 8 it
is shown a cut in a window aperture. In this cut it will
be inserted a cranial bar 50*50 mm. About the organization
of window and door apertures it is in more details written
in section "Mounting of
P.S. If it is
difficult to you to be defined, what type of a log to choose: round
or oval-flatten, we remind, that you can unite them, having made
external walls from a round timber, and internal - from an oval-flatten.

Round timber + an oval-flatten".

the house of your dream.
