Windows and doors: Acoustic performance
Open full view...Categories: Performance : Windows & Doors
The performance characteristics listed below are relevant to products covered by EN 14351-1 Windows and doors - Product standard, performance characteristics - Part 1: Windows and external pedestrian doorsets without resistance to fire and/or smoke leakage characteristics
This requirement applies to:
| Windows | Yes when required |
| Doors | Yes when required |
| Roof windows | Yes |
Doorsets and openable windows with fire resisting and/or smoke control characteristics are covered by EN 14600
Pedestrian doorsets, industrial, commercial, garage doors and windows are covered by prEN 16034
Standards
| EN 140-3 | Acoustics – Measurement of sound insulation in buildings and of building elements – Part 3: Laboratory measurements of airborne sound insulation of building elements |
| EN 717-1 | Acoustics – Rating of sound insulation in buildings and of building elements – Part 1: Airborne sound insulation |
Method of test or assessment
Direct airborne sound insulation is measured by mounting the test sample in an opening between two rooms and measuring the sound insulation at different frequencies.
Annex B of EN 14351 gives a method for evaluating the acoustic performance for windows containing a single IGU based on tabulated values.
Classification
There is no classification for direct airborne sound insulation. Where required the value should be declared in units of dB.
CE Marking
UK Regulations do not cover noise from outside the building and therefore the direct airborne sound insulation is not required for compliance. The allowable use of No Performance Determined (npd) is as follows:
| Location | npd allowed |
| England and Wales | Yes |
| Scotland | Yes |
| Northern Ireland | Yes |
