Airs but right!

InternormWindows show an optimal insulation and high Dichtheit. This avoids annoying draughts, saves heating energy and holds disturbing noise. This caused but bewusteres airs also.

So it is advisable to carry out a push ventilation (wide open window) per day repeatedly. Most effective at the with draughts by opposite windows. A ten-minutes long push ventilation carried out repeatedly daily brings the desired air exchange, does not impair the cosy room climate, however. The room temperature drops for some minutes, wall and furniture, however, can not cool the "heat accumulators" down at this time. The fresh air is warmed again in the room very quickly, the energy loss is minimal.

 
 


Insulation

optimal orientation of the houseSince for a house 25% of the energy can be lost approx. by the windows, the insulation of the window is particularly important. The energy transport at the window does only not consist of warmth losses, due to the transparency of the glass an energy profit is also reached.

At a corresponding planning the energy balance of the building can be influenced decisively by the correct order of the window areas (big window area to the south). The insulation of the window is depending on frame material, and insulating glass the Dichtheit of the window. The characteristic quantity for the checking qualities of the window is the U value. The smaller the numerical value, the better the insulation. By options like shutters and shutters an additional improvement in the U value is possible.

 
 


Noise insulation

aircraft noisesound levelsHaving an effect of noise is unpleasant and intensity and duration can have a negative effect on the human organism at corresponding. The perception of the noise is made by air pressure fluctuations which are taken over the human ear and passed on to the brain.

The sound absorption of the window is measured in decibel (dB). The more highly the numerical value, the better are the sound absorption. The sound absorption says how much sound energy is let through by the original sound energy. 1/10, at 20 dB 1/100, are let through at an insulation of 10 dB at 30 dB 1/1000 etc. of the original sound energy. The sound absorption of the window is dependent on frame material, insulating glass and Dichtheit of the window.
