The LOPAS technology


- The most sustainable construction method without compromises
- CO ² balance with less CO² emissions in the production chain than in the construction
  bounds
- 100% of ecological building materials: Wood, straw, organic fibre- clay plaster
- The highest energy efficiency
- Healthy and comfortable room climate
- No dry air during heating season
- Radiated warmth from clay plastered walls
- High storage mass due to thicker layer of organic clay fibre plaster
- Investment security by better trade-in value of a clay-passive house
   (Residential health, Energy Performance Certificate, operating expenses, disposal …)


The wall construction has been improved through the on-going development of the materials in use plus processing techniques, and is the heart of the LOPAS construction system available today.


The high storage mass of the LOPAS wall construction as well as being the most efficient natural insulation deliver, besides the factors of well-being in the home environment, above all the highest energy efficiency.
