Silver Ducting (100mm / 125mm / 150mm / 200mm / 250mm)

What is Silver Ducting used for?

Silver Ducting is flexible foil ventilation ducting used for grow tents, inline fans, carbon filters, air-cooled lights, silencers, and general-purpose air movement. It supports both intake and exhaust, and is also suitable for home ventilation like bathrooms or laundries.

What is Silver Ducting made of?

It’s made from a laminated aluminium foil and polyester layer with an internal steel wire helix. This gives it flexibility while holding its tubular shape. It’s safe for normal ventilation temps but can tear if crushed or overtightened.

What sizes does Silver Ducting come in?

Common diameters are 100mm, 125mm, 150mm, 200mm, and 250mm, each supplied in 5-meter lengths. Ducting is sold separately from clamps. Use a same-size metal ducting clamp for a secure fit.

Can I connect Silver Ducting to different duct sizes?

Yes—use a duct reducer (e.g. 200mm to 150mm) and clamp each side tightly. Just note that reducers add airflow restriction, so keep transitions smooth and well-sealed.

Can I cut Silver Ducting to size?

Absolutely. Use snips or scissors for the foil, and wire cutters for the internal coil. Wrap the cut end with foil HVAC tape to prevent fraying and improve sealing over fittings.

How should I install Silver Ducting for best performance?

Stretch it out fully, avoid sharp bends or kinks, and keep runs as short as possible. Secure each join with a clamp and seal with foil tape. Support long spans to prevent sagging or crushing.

Does duct shape and size affect airflow?

Yes. Crushed or bunched-up ducting causes turbulence and reduces real airflow. Bigger duct diameters reduce airspeed and noise. Always stretch out ducting and avoid sharp turns.

Why is my setup noisy with Silver Ducting?

Uninsulated ducting can amplify airflow noise, especially if bunched, bent, or leaking. To reduce sound, stretch the duct, seal joins, avoid sharp curves, and run the fan at lower speeds.

When should I use insulated ducting instead?

Use acoustic or insulated ducting when noise is a major concern—like in bedrooms or shared spaces—or when ducting runs through cold areas prone to condensation.

Does Silver Ducting leak smell or air?

Not if installed properly. Most smell leaks come from poorly sealed joins, not the filter itself. Use clamps for grip and foil tape for airtight seals to prevent odors or air loss.

Why is air still leaking even with a clamp?

Check that the duct is fully pushed onto the spigot, the clamp is sitting over the spigot section, and the foil isn’t torn. For best results, use both a clamp and foil tape to seal micro-gaps.

Can Silver Ducting cause condensation issues?

Yes—warm air hitting cold duct walls can create condensation. Prevent this by avoiding cold routes, stretching and supporting the duct, and switching to insulated ducting if moisture builds up.

Should I support Silver Ducting?

Yes—use straps or hangers to prevent sagging, especially in long horizontal runs. Unsupported ducting can reduce airflow, collect condensation, and wear out faster.

Can Silver Ducting be reused?

Often, yes. As long as it's not torn, crushed, or cut too short, it can be reused in new setups. Inspect for pinholes and bent wire edges before reinstalling.

How should I store unused Silver Ducting?

Keep it dry and boxed to prevent dust or crushing. Each unit is individually packed to help maintain its shape and cleanliness until installation.
