Secondary Glazing for Schools and Universities

The Problem

Schools and universities in urban locations frequently suffer from external noise that disrupts teaching and learning. Road traffic, construction noise and general urban sounds penetrate standard windows readily, reducing the quality of the acoustic environment.

Building Regulations

Building Bulletin 93 (BB93) sets acoustic standards for UK school buildings, including requirements for noise levels from outside. Secondary glazing can help existing buildings meet or approach these standards without the need for full window replacement.

Recommended Specification

For school and university applications we recommend reveal-fixed installation with 6.8mm or 8.8mm acoustic laminate glass and a 150–200mm air cavity. This achieves 49–54dB noise reduction — sufficient to significantly improve the acoustic environment in most urban educational buildings.

Installation During Holidays

For schools and universities, we schedule installation during holiday periods to minimise disruption to the academic timetable. Multi-room programmes can be completed efficiently during summer holidays.
