Air-Tightness
The air leakage test was performed under both positive and negative chamber pressures, simulating real-world scenarios of air pressure changes.
The lower the air leakage rate, the more airtight the product. A rate of less than 3m³/h qualifies as smoke sealed for building regulations.
| Pressure (Pa) | Air Leakage Rate (m³/m/h) (Positive Chamber) | Air Leakage Rate (m³/m/h) (Negative Chamber) |
|---|---|---|
| 25 | 1.77 | 2.06 |
Acoustic rated
UKAS-accredited independent laboratory tested to a reduction of 47 dB Rw to BS EN ISO 10140-2:2010.
This is a real-life equivalent of reducing the sound of a vacuum cleaner to the same noise your computer is making.
Fire Rated
Available with up to 2 hours fire rating. Fire testing undertaken independently by BM TRADA meeting both EN and BS standards in UKAS approved test laboratories. Certification available upon request.
