Reducing noise break-in issue on new school roof, Chester

Hush Acoustics provided an effective solution to ‘noise break-in’ at a newly built primary school in Chester to ensure the internal acoustic environment was supportive of learning goals.

The Huntington Primary school was designed by Cheshire West and Chester Council to cater for 420 primary age pupils and a 26-provision nursery. The former primary schools it replaced had a capacity of 120 children, but to cope with the demand of 1,200 new houses being built nearby on the former Saighton Army camp, the decision was made to build a new school to meet the requirements.

An acoustic concern highlighted was ‘noise break in’ which is caused by issues such as the sound of rain falling onto the roof, which in turn would detract from the learning environment. In order to resolve this potential issue and to guarantee the children a healthy setting free from noise disturbance, we specified our Hush 10kg Barrier Mat to be installed in the roof of the building.

Hush Barrier Mat is a vinyl sound barrier mat loaded with naturally occurring minerals. The product is free of lead, unrefined aromatic oils and bitumen. Designed to improve the sound insulation of existing panels of metal, wood, plastic etc., at all frequencies. The mat is normally fixed in intimate contact with the original panel. Hush barriers are particularly effective in overcoming coincidence dip resonance found in stiff lightweight composites such as plywood sheets and hollow core panels.

Working alongside Kier, were Delta Group, who we supplied with 1100 sheets of our Hush 10 kg Barrier Mat. They then applied this to the roof of the school in 3x layers, to give a mass of 30 kg/m2 and improving acoustic performance across all frequencies.
