Insulated Flexible Air Duct - 12 in x 25 ft

Insulated Duct That Steadies Room Temperatures - 25 ft Section

Air moving through bare duct picks up or loses heat on the way, which makes temperature control harder in a cultivation space. This insulated flexible duct uses thick, durable layers of insulation to limit that exchange, and it keeps its structure in air up to 140°F.

The 12 in diameter, 25 ft section suits a regular indoor grower running an exhaust or intake line between a fan, filter or hood and the outside of the room. One section often covers a single run, and a commercial room can order several for multiple lines.

Key Features & Benefits

• Insulated construction — thick layers help reduce heat gain and loss along the run.
• Heat tolerance — holds its structure in air up to 140°F.
• 12 in diameter — fits 12 in ventilation connections.
• 25 ft length — one section reaches across most room layouts.
• Flexible design — bends around obstacles instead of needing rigid elbows.

Who Should Use Insulated Flexible Air Duct

Use it if you vent a cultivation room through unconditioned space, such as an attic, a garage or a hallway, and want steadier air temperature. It also suits growers who want less temperature swing in hydroponic or indoor setups.

About This Insulated Flexible Air Duct

This is a 12 in x 25 ft insulated flexible air duct for ventilation. It is sold each, as one 25 ft section. The distributor describes it as having the same quality and reliability as its regular air ducting, with added insulation.

Frequently Asked Questions

Q: What does insulated duct do that regular duct does not?
A: Insulation slows heat moving through the duct wall. That helps the air arrive closer to the temperature it started at, which supports steadier room control.

Q: How long is one unit?
A: Each unit is a single 25 ft section. It is sold as one piece, not as a pack.

Q: What temperature can it handle?
A: It maintains its structure in air up to 140°F. Keep exhaust air from hot equipment within that limit.

Q: Can I cut it to a shorter length?
A: Flexible duct of this type is generally cut to length for the run you need. Seal the ends with clamps or tape to the connected equipment.

Q: What does insulated duct do for noise?
A: Insulation layers can slightly dampen airflow noise, though results depend on the fan and the layout. Keep the run as straight as you can.
