An elephant never
forgets
With semi-rigid ducting, you don't have to worry about flexible ducting ripping or sagging and impacting your airflow. Elephant Duct stays right where you put it.
Less Sagging
Puncture Resistant
Ducting built differently
Elephant Duct is a pre-insulated, semi-rigid ducting system designed for professional HVAC and ventilation installations. It gives installers a cleaner, more robust alternative to traditional flexible ducting, with insulation and protection built into the system.
Choose Elephant Duct
We didn't set out to make another standard ducting product — Elephant Duct was designed to challenge existing UK giants. With semi-rigid flexibility and pre-installed insulation, our ductwork installs faster, holds its structural integrity, and drastically reduces on-site lagging labour compared to traditional metal or flexible lines.

Before semi-rigid ducting, HVAC engineers were torn between two choices: flexible PVC ducting which can rip and sag during installation, or bulky rigid ducting requiring pin-point coordination to fit correctly.
Our pre-insulated semi-rigid ducting offers the perfect balance of flexibility and robustness. Prioritising easy installation, lasting performance, and a lower environmental footprint, Elephant Duct is the ideal choice for modern HVAC systems.
Technical Overview
With semi-rigid ducting, you don't have to worry about flexible ducting ripping or sagging and impacting your airflow. Elephant Duct stays right where you put it.
Our ducting is built to withstand temperature differences — that means less condensation, more predictable humidity levels, and a tougher environment for bacteria and mould to thrive.
In case the worst happens, it's best to be confident that your ducting won't catch fire — however many products on the market today aren't fire-resistant. Our line of ducting is built to withstand some tough conditions, meeting multiple strict European fire safety standards.
Available in standard sizes Ø50mm to Ø315mm with 10-Year Warranty coverage.
All costs are estimates.
Flexi-duct isn't shown as it's legally only permitted for runs under 200mm under ADF 2026.
Big money is spent on providing the most efficient HVAC units, but these often fail to meet their low-energy promises when in use. Often, cheap and/or poorly-installed ducting is the problem. Bends, rips, and weak connections can create pressure drops, impacting your air quality and degrading your HVAC performance over time.

Designed in Italy, our ducting range meets strict fire safety standards: Class 1 (D.M. 26/06/84) and Class B-s1, d0 (EN 13501-1:2019) across Europe — among the highest ratings for limited flame spread, low smoke, and no flaming droplets.
In simple terms, our ducts give off very little smoke and help prevent flames from spreading, making them ideal for safety-critical environments or sites with strict fire regulations.
Our ducting combines a netted, closed-cell polyethylene foam insulation layer with a high-performance polyolefin film, providing excellent thermal efficiency (R = 0.12 m²·K/W), reduced heat loss, and minimal condensation. Suitable for air conditioning, mechanical ventilation, and industrial air systems, Elephant Duct ensures reliable, energy-efficient air control in even the most demanding environments.
Elephant Ducting is engineered for easy installation and lasting performance, featuring a multi-layer polyolefin construction reinforced with an embedded steel wire helix for exceptional flexibility and shape retention. It accommodates smooth bends and tight curves without kinking or compromising airflow, with a compact bending radius of just 1.2–1.8 times its diameter, making it ideal for complex layouts, confined spaces, and challenging installations. Lightweight yet durable, it saves valuable on-site time while delivering consistent performance across air-conditioning, mechanical ventilation, and industrial systems, demonstrating that true flexibility can coexist with strength.
Elephant Ducting is designed for long-term durability, resisting deformation, punctures, and wear. Its robust materials withstand the demands of repeated handling, tight bends, and high airflow pressures, while maintaining structural integrity and consistent performance over time. Lightweight yet tough, it delivers reliable service in air-conditioning, mechanical ventilation, and industrial systems, ensuring both longevity and minimal maintenance in even the most demanding environments.
