Heat Resistant Duct Tape – 48m Silver Aluminium Foil RollHeat Resistant Silver Foil Tape (48 Metre)£5.95
Description
Quieter extraction without choking your airflow
Ultra Silent Ducting from Hydro Crop Shop is flexible acoustic ducting built to dampen the drone of an inline fan running around the clock, supplied in 5 or 10 metre runs so you can route between fan, filter and vent in one piece without part-way joints. Standard thin-wall or lay-flat ducting lets that hum travel straight into the room below, which becomes a real problem when extraction runs overnight in a shared house or near neighbours. Swapping to a proper acoustic duct is one of the simplest ways to bring the noise down without touching your fan or filter.
Key Benefits
- Layered acoustic construction with a foil outer and interwoven inner layer that absorbs sound rather than reflecting it
- Anti-kink spiral wire holds the duct open through bends so airflow isn't strangled
- Non-allergenic build with no glass wool, so nothing sheds into the airstream
- 5m and 10m lengths cover short and long fan-to-vent runs without extra joints or leaks
- Easy to trim to the exact length with scissors or wire cutters
- Fits standard fan and filter flanges using ordinary duct clamps
How to Use
- Measure the run from fan to filter or vent and cut a little longer than needed to allow for gentle bends
- Slide the cut end over the spigot and secure with a duct clamp or strong tape for an airtight seal
- Repeat at the other connection
- Keep runs as straight as possible and avoid crushing the duct at tent ports, as flattened sections restrict airflow and reduce the sound-dampening effect

Questions & answers
What sizes and lengths are available?
5m lengths in 125mm, 150mm, 200mm, 250mm and 315mm, and 10m lengths in all of those plus 100mm.
How do I fit it to a fan or filter?
Slide the end over the spigot and secure it with a duct clamp or jubilee clip, or strong tape, for an airtight seal. It fits standard fan and filter flanges.
Can I cut it to length?
Yes. Trim it with scissors or wire cutters, cutting a little longer than the run to allow for gentle bends.
Does it contain glass wool?
No. It has a foil outer and an interwoven acoustic inner layer with no glass wool, so nothing sheds into the airstream.
How do I get the quietest result?
Keep runs as straight as possible and don't crush the duct at tent ports, as flattened sections cut airflow and sound-dampening. For more, add a duct silencer close to the fan.
