St Edwards School in North London were having trouble with noise pollution from the school gymnasium. The room was split into two with foldable acoustic doors. This meant that when the room was being used for two different groups, neither side was able to conduct activities without being able to hear the other sides noise coming through the divide.
When we were asked to make an assessment we found that there was a weak spot in the breeze block above the acoustic door. The issue should really have been dealt with by the initial building company when installing the doors.
Metropolitan Insulation installed a MF acoustic 12cm wall with independent aluminium framework. This also comprised of 1 layer of fermacel, a sound shield layer and all edges were properly sealed.
This dramatically reduced the noise leakage and the school was able to conduct separate activities simultaneously in the gymnasium.
