- Rebound (% after compression to z”): 80% +/- 20%
- Long Term Flexibility: Indefinitely Flexible
- VOCs: 0
- Surface Burning Characteristics: ASTM E-84 Test
- GreenSeam Plus Transverse Gasket applied to Galvanized Steel.
- Test Results: Flame Spread Index – 0
- Smoke Developed Index – 30
- Test applied in two 3/8” wide strips 8” on center (coverage of 3% of the exposed test sample area)
