Wood is a natural material, growing and adapting depending on weather conditions.
Despite the technical drying methods it is, nonetheless, impossible to completely prevent it from some degree of warping and formation of resin and cracks, especially on the outside surfaces.
The varying knot formations are also typical of spruce. These variations accentuate the beauty of wood.
It is technically impossible to produce absolutely stagnant material from trees, even by using the most sophisticated production methods, since the material literally grows out of the earth.
Due to constantly changing temperatures and the varying level of moisture in the air during the course of the year, combined with the rain, wind and sunshine, wood will always shrink and swell alternately, as the pores absorb moisture and dry out again. It is possible that the timber may warp a little, but this does not affect the stability and functionality of the structure. The swelling and drying of pores in the wood also leads to wall settling. And this is the reason why doors and window frames are not fixed to the wall logs but loosely inserted into the walls. This is the best way to ensure that the natural wood movement does not cause any damage.
The timber we use is absolutely untreated, except for the impregnated floor beam parts. If timber is exposed to harsh exterior climates, it needs to be protected from the damaging effects of weather changes, sunlight, moisture and biological infestation.
It means, that it will turn greyish over the years. To guarantee the longevity of your Log Cabin (which should be at least a lifetime), we recommend to treat it with three coats of quality preservative. It is not advisable to paint the wood before assembling the logs – this is best done when the cabin is already constructed and the weather is fine. However, if you wish to paint odd parts in different colours, this should be done before the cabin is assembled.
An adequate ventilation and the prevention of water penetration are the best ways to protect wood from rotting.
