Log Cabins -FINN FOREST

Structure
The ingenious structure of planed logs allows for quick and easy assembly. The fit is always perfect, the seal tight and strong. Scarfed corners add an elegant finishing touch to your cabin.

Log Strength
Cabins come in three different log thicknesses. Those constructed with the sturdiest planed logs are best suited for heavy wear, and can even serve as small cottage, for example.

Thermowood -FINN FOREST

Background
ThermoWood is manufactured using a method developed by VTT. The wood material is heated to a temperature of at least 180 degrees Celsius while it is protected with steam. Besides providing protection, the steam also affects the chemical changes taking place in the wood.

Stability
ThermoWood has improved stability when compared to normal kiln dried pine.

The internal stresses within the structure of timber are reduced when it is treated to the high temperatures of the ThermoWood process. This reduces the potential for twist and warp. In addition there is a decrease in the equilibrium moisture content and water permeability. There exists a linear correlation between water intake properties and dimensional stability of the material under changing moisture conditions. Swelling and shrinkage of ThermoWood is only 50% of the corresponding values of untreated Nordic pine and is in a similar range to teak.

Durability
Finnforest ThermoWood has improved durability due to the degradation of hemicelluloses (arabinose, galactose, xylose, mannose). These are the foodstuff for rot-causing fungi and bacteria and in the absence for nourishment they are not able to occupy ThermoWood
