An OTT Haus provides special advantages that you don't see in the house at first glance, but rather feel. In the long term you feel better in an OTT house and various factors that are taken into account when building a house. It creates no condensation in the walls, does not mould and retains value even after years. The pleasant room climate is important.

1. Fresh air oasis - a new system that saves energy and promotes good health
2. No chipboard ejecting formaldehyde; healthy gypsum fiberboards that absorb moisture like clay plaster
3. No plastic foils but breathable walls for wall and roof structures
4. No styrofoam - breathable, less condensation, fire protection
5. Very high sound insulation, less noise emission - sleep soundly
6. High heat protection. Warm in winter and cooler in summer due to wood fibre and cellulose insulation
7. Gypsum fibre boards, *Fermacell*, that absorb and neutralize pollutants (sounds incredible - is true!)
8. Fire protection: as we have tested, OTT houses are not only healthier but also safer!
9.  *Fermacell* is sound, fire, impact and moisture resistant. Load carrying 30kg per screw. Fermacell is used on all walls, much stronger. NOT plasterboard
