Key contribution
ISOVER insulation solutions contribute to reducing acoustic disruption by limiting external noise intrusion.
Aim
To reduce acoustic disruptions by limiting external noise intrusion.
Detailed requirement
Part 1: Sound Pressure Level
Each regularly occupied space meets the following sound pressure level as measured when the space and adjacent spaces are unoccupied, but within 1 hour of normal business hours:
- Average sound pressure level from outside noise intrusion does not exceed 50 dBA.
Part 2: Sound Pressure Level in Residences
Each regularly occupied space meets the following sound pressure level when the space and adjacent spaces are unoccupied:
- The sound pressure level from outside noise intrusion is less than or equal to 40 dBA based on the peak hour Leq.
Part 3: Acoustical Narrative
The project team provides a narrative describing:
- The sources of external and internal noise considered in design.
- The strategies undertaken to manage these sources.
Part 4: Sound Pressure Level in Schools
Each regularly occupied space meets the following sound pressure level when the space and adjacent spaces are unoccupied:
- Spaces equal to or less than 6,000 m² [20,000 ft²]: average sound pressure level from outside noise intrusion is less than or equal to 35 dBA.
- Spaces greater than 6,000 m³ [20,000 ft³]: average sound pressure level from outside noise intrusion is less than or equal to 40 dBA.

Our contribution
Part 1
Sound absorption is optimized for outstanding acoustic benefits by using ISOVER’s lightweight mineral wool products, including glass wool and the Ultimate range of materials, that are suited for mass-spring-mass systems. Sound comfort can be improved considerably by paying careful attention to heating and ventilation systems, and can be achieved when using ducts made of reinforced mineral wool such as ISOVER CLIMAVER®.
