Noise Reduction

Secondary Glazing is extremely effective in noise reduction. This can play a significant part in the comfort and effective use of a building or room. Noise wherever it is generated, will impact on the effective use of a sales office, meeting room, library or classroom. Noise pollution from a busy road, railway line, airport or industrial estate is substantially reduced using the Clear View system. 

When at home, unpleasant or disruptive noise is extremely annoying, particularly if you want to relax, sleep or concentrate. Even the most basic of our Secondary systems will have a significant impact on noise reduction, we can also install specialised Acoustic glass to further subdue the passage of sound.

Clear View’s units have been tested for sound reduction at the AIRO Acoustics Laboratory ( an accredited NAMAS Testing lab, number 0483 ) in accordance with BS2750: part 3 and BS5821: part 3 1980 : 1984, using a purpose built sound transmission suite. The findings of these tests can be seen by clicking here.
These tests were carried out in November 1997 as part of an on-going research and development programme.
