The foundation is the lowest and most crucial supporting layer of the whole building structure. It is also the part of the building part that is the most difficult to change after the building has been erected, so it is essential to design and insulate it well from the beginning.
The external walls of a building function as a climate shield. They protect against cold, precipitation, strong winds, noise and fire. A good external wall structure, with the right insulation solution, is a prerequisite for a healthy and pleasant indoor climate.
