Fire
Metal ceiling panels are inherently incombustible, however the paint surface and acoustical fleece backing can contribute
to fire if not properly formulated. RH 200 Plank System panels have been tested according to ASTM E 84 and are certified Class
A by Factory Mutual:
- Flame spread: less than 25
- Smoke generation: less than 50
Acoustics
Acoustical correction is provided by the factory application of a black acoustical fleece. Additional correction can be provided
by the addition of a fiberglass pad behind the fleece.
- NRC rating, perforated with fleece: 0.65 (12% open) to 0.70 (40% open)
- NRC rating, perforated with fleece and fiberglass pad: 0.90 (22% open)
Light Reflectance
Light reflectance of Fastrack Systems is dependent on the selection of color and perforation. The results below were obtained
using a photospectrometer with a D65 10 degree setting: perforated panels were backed with black acoustical fleece.

Air Flow
Fastrack Systems are not normally considered for use as air supply or return elements. However, pressure drop and flow rate
data is available from Armstrong on variety of perforation types.
Exterior Applications
The Fastrack System is designed essentially as an interior system. However, under certain circumstances the system can be
installed in exterior soffit situations. Modifications to meet exterior requirements will typically include:
- Exterior coating finish specifications
- Restricted panel sizes to meet specified wind loads
- Additional hold down clips and increased frequency of support elements
Call 877-ARMSTRONG for full data and test results on the performance topics listed above.
