After several days of hammering and the preparation of timber for the stud walls, it is now much quieter in the hall. The R2.5 insulation wool has been inserted into the roof space and the new foam walls. As well as its insulating properties, it has a sound proofing capacity as well. It is working wonderfully on the noise out the front, so we hope it will have an equal effect on the sometimes loud rows from the junior apprentices.
