THERMOline
solid wood construction - without additional insulation
With our THERMOline construction method, the wood takes the role of traditional thermal insulation. Due to their multi-layered, monolithic construction, the modular THERMOline building elements provide a comfortable and healthy indoor climate.
Due to the excellent heat storage capacity of the solid wood elements, this construction method protects against overheating in summer and insulates in winter. THERMOline thus ensures a manageable energy demand and is considered fire safe.

Solid wood elements are suited for interior and exterior use and available in various wood species and surface qualities. For visible surfaces, choose or combine spruce, larch, stone pine, fir or pine. Further finishing of the wooden surfaces is individually possible, e.g. by treating the planed, sanded or brushed surfaces with glazes, paints or oils.
build upon the unique qualities of solid wood
Compared to other construction methods, solid wood offers, among others, the following advantages:
- - quick assembly of prefabricated solid wood elements
- - quiet and clean assembly without heavy machinery
- - lighter than traditional building materials like brick and concrete, simplifies transportation and assembly
- - high energy efficiency, good insulation reduces the energy demand of the building
- - less waste and a better energy balance
- - stable and durable, suitable for buildings that must withstand earthquakes or other natural disasters
