ESTPANEL OÜ manufactures buildings with squared log walls.
We use high quality pine and spruce timber industrially dried to a moisture content of 16–18%.
The construction of a log house is very specific due to the natural drying of square logs. For this reason, the entire structure is designed in accordance with the sinking log wall which does not prevent it from sinking.
