The retention of heat is outstanding as there are no cold bridges, and the full amount of energy required can be produced from renewable sources. Another advantage is speed, since we build a 100-square-meter building in 15 days. Such houses also effectively absorb noise coming from the street or from inside, thereby creating a pleasant atmosphere.<br>Environmental protection is the primary goal of low-energy buildings and maintains ecological awareness starting from the origin of raw materials, their production, packaging, transportation, construction and use to 100% recycling possibilities.
