Key contribution
ISOVER solutions permit a reduction in sound reverberation.
Aim
To reduce sound reverberation and maintain comfortable sound levels though absorptive ceiling and wall surfaces.
Detailed requirement
Part 1: Ceilings
The following spaces, if present, have ceilings that meet the specifications described:
- Open workspaces: minimum NRC of 0.9 for the entire surface area of the ceiling (excluding lights, skylights, diffusers and grilles).
- Conference and teleconference rooms: minimum NRC of 0.8 on at least 50% of the surface area of the ceiling (excluding lights, skylights, diffusers and grilles).
Part 2: Walls
The following spaces, if present, have walls that meet the NRC specifications described:
- Enclosed offices, conference and teleconference rooms: minimum NRC of 0.8 on at least 25% of the surface area of interior surrounding walls.
- Open workspaces: minimum NRC of 0.8 on at least 25% of the surface area of the surrounding walls.
Partitioned office spaces: partitions reach at least 1.2 m [48 inches] and have a minimum NRC of 0.8.
Part 3: School Ceilings
The following spaces have ceilings that meet the specifications described:
- Spaces less than 6,000 m³ [20,000 ft³]: NRC of at least 0.7 for the entire surface area of the ceiling (excluding lights, skylights, diffusers and grilles).

Our contribution
Parts 1 and 2
Referring to criteria number 78, ISOVER solutions can limit reverberation time. This will help to reduce sound reverberation and permit acoustic comfort to be improved.
