While we are prepared to put up with a level of noise during our daily activities, we all value a peacefull and relatively quiet home life.
Noisy neighbours, loud radios or constant street noise can be very distressing and can even lead to ill health.
Paarhammer windows and doors can eliminitate such irritations with a range of noise reduction products.
Every 10dB reduce noise levels by halve
Noise is measured in decibels (dB). which is a logarithmic scale to relative changes in loudness. For every 10dB change the noise is perceived twice or halve as loud. As such a 20dB reduction would reduce the noise by four times.
The performance of a window cannot be determined from that of the glass element alone.
sound aborption
The glass and frame together determine the acoustic insulation performance of the entire window and in some cases the entire facade.

Choice of glass and airspace can virtually eliminate noise
The average single-glazed window has a sound barrier of only 23-25 percent.
Paarhammer windows and doors have excellent sound insulation with a sound barrier of up to 45dB. This reduces noise levels by approximately 80-90 percent.
