Aluminum
| Material | Special aluminum foil with increased flexibility from polyester fiber sheets |
|---|---|
| The thickness includes the adhesive | 75 microns (adhered onto the steel spring), making the area around the steel spring total 90 microns. |
| Test results | Passed the BS-476 fire resistance test |
| Properties | lightweight, flexible, once pulled can extend straightly to 10 meters without retracting, the duct’s width is sufficient for the airflow that passes, lessens the loss of air and sound well, easy to install, suitable for low to medium wind flow speeds and temperatures that aren’t drastically different |
| Thermal resistance | -20 -150◦C |
| Pressure resistance | 250 mm WG |
| Size | Length | Wire size | Foil thickness | Wind speed |
|---|---|---|---|---|
| 4” – 6” | 10 M. | 1.0-1.4 mm | 75 microns | 28M/S |
Fiber glass
| Material | Special aluminum foil with increased flexibility from polyester fiber sheets, assembled with steel springs |
|---|---|
| Structure | Adheres to the structure with an aluminum foil layer on top and underneath, coated with a 25 mm. layer of fiber glass |
