G.A.S White Combi Ducting 2.5m — Reflective Outer Coating

G.A.S White Combi Ducting 2.5m — Polyester & Aluminium with Reflective Cover

G.A.S White Combi Ducting made from top-quality, airtight polyester and aluminium mixed with a steel helix wire — strong, resistant, and durable. The white reflective outer cover reduces noise from airflow and reflects heat and light away from the duct. Your grow room's ventilation system operates more efficiently with this proper-grade ducting compared to standard combi flex.

Why growers choose G.A.S White Combi:

• Polyester + aluminium + steel helix — multi-material construction, properly engineered
• White reflective outer cover — reflects heat and light, reduces grow-room temperature gain
• Reduces airflow noise — outer cover dampens noise vs uncovered alloy ducting
• Strong and durable — survives years of grow-room use without degradation
• Airtight construction — no air leaks at the duct itself
• Steel helix maintains shape — doesn't collapse under extract suction
• 2.5m practical length — enough for short runs or repair work

Who it's not for:

Not as quiet as acoustic ducting (RAM Sonoduct, Phonic Trap) — for serious noise reduction, step up to acoustic alternatives. For longer runs, 5m or 10m roll lengths are better value than multiple 2.5m sections. Check the diameter matches your fan and filter — wrong size won't fit. For darker grow rooms where reflectivity isn't needed, standard alloy combi is cheaper.
