Does the spruce have the necessary qualities for log house building?

Yes, it does if it was exploited from the appropriate place and time. The logs we use are exploited from a height which is at least 1000 m above sea level, in the appropriate season, and according to the proper position of the moon. Taking these criteria into consideration, the solidity of such spruce, having small annual rings, has the solidity of hard wood.

Does the log house often have to be maintained?

Once in 5 or 10 years. During the manufacturing process the logs are treated with water based treatment against fungi, insects and mildew.

How long does the drying of the wood and the shrinkage of the building last and how can these be taken into consideration with respect to the doors and windows?

They last for a couple of months but total drying and shrinkage take 3 to 5 years, depending on climate and height above sea level.
We work from raw wood , in this condition wood is easier to shape. By our technology wood dries built into the house, in a natural way. Shrinkage is influenced by the quality of wood, this is why we use only wood with even growth and without twisting. Due to this fact there is no tension inside the log and the gaps which may appear are fewer and smaller. During drying spruce loses 4-8% of its volume.
Taking 5% shrinkage, a 2.10 m high door can lose 10.5 plus 2 cm safety luft.

What is the humidity content in a loghouse, how often does dusting need to be done?

There is constant humidity content in a loghouse and due to this fact there is less dust in the airspace.

How are the logs insulated?

A very good and natural material for insulation is hemp. For this purpose wool and cotton (rock wool) can also be used.

Is the loghouse hot and light?

The heatstoring capacity of wood is twice that of lime brick for example, thus a loghouse can be heated with less fuel. A loghouse needs more source of light than a traditional
white-washed house. A large window is a good source of light and heat in winter when the position of the sun is low; at the same time with appropriate shading, the log house will not be overheated during summertime.
