Noise reduction internal secondary double glazing for St Patricks Church Bolton

Client: St Patrick's Church

The congregation can once again, worship and contemplate without interruption in this cavernous Grade II Listed Church, following acoustic adaptations to block the noise from the new Bolton Trinity Interchange next door. With the new transport hub on the opposing corner of the road, the hum of stationary busses reached in the region of 70-80dB, which could be heard in the church causing a nuisance to the parishioners. A total of 7 windows were treated with acoustic internal secondary double glazing, with a good cavity to reduce the noise ingress. The tall clerestory gothic arches received Series 41 double side hung casements transom coupled to Series 46 fixed lights. A window at the back of the church near the entrance required S41 side hung casement’s mullion coupled side by side with a transom to couple a Series 46 fixed light above. However, the chancery window at 4.3m (h) x 3m (w) was made up with four different units: Series 80 3-pane horizontal slider transom coupled to three Series 41 mullion coupled curved casements above. When now inside the church, you would never know there is a bus interchange just outside; the acoustic secondary glazing treatment has worked miracles.
