To lock out traffic noise and aircraft noise!

In our densely populated living environment it is difficult to exclude all kind of sound noises. But you can do a lot against the noise nuisance with the choice of the correct material and with the help of the correct construction technique. Given that you have to air often, all noise protection measures are without success, if you open the windows. The new government want to cancel partially or totally the night flight interdiction; this will be a real horror for a lot of residents at airports.

But with the local ventilation apparatus of GF-SOL-AIR you will get fresh air and at the same time all noise from outside will be locked out with a high damping value (48 dB). This happens mainly due to very small wall gaps, which only present a small sound absorbent surface. Further damping is accomplished by the heat exchanger and the internal noise dampening. What is the meaning of 48 dB? Sound energy will be reduced by the factor 63000!

Ears never sleep, because the evolution needs them in order to give alarm, if there is any kind of risk. This means in modern times, you have only a less chance to sleep well because the noise of outside influence our sleep. The consequence is that we are tired, we can not concentrate and we are sensitive against all kind of pressure. If we would not open the windows, we would also have headache, bad temper etc due to too much carbon monoxide.

We advise you to do anything good for yourself. Use the Comfort Ventilation System CVSrobusto and you will have fresh air at any time, you will not suffer of any kind of noise and at the same time you will economize a lot of heating costs.
