Climate protection and energy conservation with AEROSIL® fumed silica


Thermal Insulation_Aerosil
The greenhouse effect and global warming have been a paramount issue for many years. But how can this enormous problem be solved?


Making increasingly greater use of regenerative sources of energy is one way of tackling the problem. Alternatively, we can reduce energy consumption — through improved insulation, for example. In Europe 35 percent of primary energy is used by households. There is, however, still much potential for energy conservation in industry and the transport sector, as well. Efficient forms of insulation can help to substantially reduce CO2 emissions. They can also help to achieve significant cost cuts as energy prices continue to rise.

AEROSIL®, a fumed silica developed by Evonik, is an excellent insulator with a very low λ- value of < 20 mW/m•K*, and it enables an exponentially greater degree of heat insulation than do conventional heat-insulation systems like polystyrene or polyurethane foams, glass wool or rock wool. Many of these traditional insulation materials were originally conceived back in the 1950s. They no longer constitute state-of-the-art technology and have reached the limit of their physical capacity to produce effective insulation. That is why AEROSIL® has popularly become the solution of choice in efficient insulation systems.


Reducing energy consumption levels is the key to reducing CO2 emissions and thus arresting global warming. In many countries this ecological imperative is being acted upon through legislation — for example, stricter building regulations or the introduction of energy-efficiency classifications for household appliances.


Diminishing energy consumption through better insulation also helps to significantly reduce costs. Investments in efficient insulations quickly pay off in the face of continually rising energy costs.
