The tightness of the structures ensures the energy efficiency of the building. It is important to note that the tight construction does not eliminate the most important feature of log as a material – i.e. breathability. What this means is that the log wall will still efficiently balance any moisture or temperature variation in the interior air.
In a Finnlamelli log house, you will always breathe healthy and fresh air.
The tested houses have featured standard Finnlamelli products, which ensure the tightness and energy efficiency of the house as long as the construction is carried out according to the instructions.
