TerraCORE® P
Sound Absorption Data
Relative Humidity: 53%
Relative Temperature: 20.2 Degrees Celsius
Specifications: The test specimen measured 2.43 m by 2.72 m (95-1/2" by 107"). The infill had a nominal weight of 1.5 kg per square meter (0.31 lb/ft2). The infill was covered with a fabric which had a thickness of 0.53 mm (0.021") and weighed 0.30 kg/m2 (0.06 lbs/ft2).
Procedure:
The Sound Absorption Coefficient is the full room absorption minus the empty room absorption divided by the area of the sample in m2. The Sound Absorption Coefficient is dimensionless.
For the empty and full room measurements, ten decay measurements were conducted at each of the five microphone positions. Data was obtained at 1/3 octave band frequencies ranging from 80 to 5000 hertz. The air temperature and relative humidity conditions were monitored and recorded during the measurements.
EXTRA
Installation shall be done only when all wet work has been completed and dried. Temperature and humidity conditions must match the normal conditions in the occupied space. The humidity of the room shall not drop under 25% or exceed 55%. The HVAC system shall be functioning continuously before, during and after installation.
It is important that plenums have proper ventilation, especially in high moisture areas. There shall be no excessive build up of heat in the installation areas. Prior to the start of installation, all exterior windows and doors are to be in place, glazed, and weather-stripped. The roof is to be watertight.
Mechanical, electrical, and other utility service installations beyond the wall or ceiling plane shall be completed. No materials should rest against, or wrap around, the wall or ceiling attachment components or connecting hangers. Review the TerrAcoustics™ Installation Guidelines for details on the appropriate project site conditions prior to installation.
TerrAcoustics™ panels shall be delivered to the project site in original, unopened packages. Any damage to package material, discrepancy in quantity or errors should be put in writing and submitted immediately to the Contractor. The TerrAcoustics™ panels shall be stored flat and level, in a fully enclosed space as per section of these specifications.
The panels shall be stored in the room in which they will be installed at least 96 hours before the installation takes place and allow to acclimatize. Factory finished products require up to a week or more on site for acclimatization. The room conditions, namely the room’s temperature and humidity shall match the conditions that will be normal in the occupied space.
Store the TerrAcoustics™ panels off the ground, on a pallet. TerrAcoustics™ panels shall be handled in a manner that will protect them from any type of damage. Review the TerrAcoustics™ Installation Guidelines for details on how to store, handle and acclimatize the panels prior to installation.
Upon completion of the TerrAcoustics™ installation, remove dust from surface, grooves and penetrations by vacuuming using only a soft brush. DO NOT scratch wood surface with sharp metal or plastic vacuum attachment. Remove pencil marks with soft erasure. Remove general surface dirt, dust, grease, oils, and fingerprints with a soft damp warm cloth with a mild diluted cleaning agent. Wipe dry with a soft dry cloth. Do not use cleaners with grit or cloths that could scratch the wood surface.
