By the mass employment of the performing green construction material the intention is to enhance a new standard of dwelling, an improved life style with more comfort and well being in the necessary respect for the surrounding environment. Just the production and adoption of SILICAWOOD® can contribute to significant changes and improvements expressed at different levels:

  • Quality of dwelling space: thermal and acoustic insulation , breathability, fire resistance, anti seismic stability, durability and guaranteed safety and soundness
  • Energy saving; reductions in CO2 emissions related to the operational management of a house with much lower energy consumption for heating and cooling and. Largely reduced energy bill kW/h
  • Respect for the environment: Carbon capture and storage (CCS) expressed in long term storage of CO2 into the SILICAWOOD® products/houses. Timber products notoriously subtract CO2 to the atmosphere from the beginning to the end of their life cycle. Each cubic meter of Silicawood stores about 250 kg of carbon.
  • Eco-friendly production process: reduced low CO2 emissions with respect to the other construction material production processes with high energy intensity and high carbon values such as for metals and chemicals.
  • Incentive for reforestation programs (public or private) cultivation of forests or plantations purposely grown. Reduction of the intensive exploitation of the quarries.
  • Collection and recycle of wood scraps & wastes as opposed to disposal in landfills or conversion into biomass for energy production extends over time the ability of these materials to continue to act as reservoir of the carbon that forests had once absorbed. At End of Life cycle of SILICAWOOD® products walls and slabs con be grinded and employed once again for making other walls and slabs

The WIN WIN motto could be:
