At i-sells, we specialise in supplying a wide range of plastic ducting for domestic and commercial ventilation systems. Whether you’re a DIY installer working on a bathroom extractor fan or a trade professional managing large HVAC projects, our uPVC plastic ducting provides the perfect solution for efficient air movement and extraction. With nationwide UK delivery and expert support, we make it easy to get the exact components you need.

Our ducting is manufactured from durable, lightweight white PVC, offering excellent resistance to corrosion, moisture, and temperature variations. It’s designed for maximum airflow, with smooth internal surfaces that reduce friction and pressure loss – ensuring optimal performance across various ventilation setups.

Round Plastic Ducting – 100mm, 125mm, 150mm

Our round plastic ducting is ideal for use in ceiling voids, lofts, or direct-to-wall extraction setups. Commonly used for bathroom fans, kitchen cooker hoods, and tumble dryer vents, this type of ducting offers easy installation and strong airflow performance. We stock the most popular round sizes:

• 100mm (4”) – The most common size for bathroom extractor fans
• 125mm (5”) – Suitable for mid-sized systems or long duct runs
• 150mm (6”) – Ideal for high-power kitchen extraction and HVAC units

All round ducting is available in a variety of lengths, bends, connectors, and accessories to build a complete system.

Rectangular & Flat Channel Ducting – Compact, Low-Profile

Our rectangular ducting (also called flat channel ducting) is the perfect choice for space-saving installations, such as above kitchen cupboards, in tight ceiling spaces, or behind plasterboard walls. This form factor is especially useful where round ducting is too bulky.

We offer multiple sizes to suit your airflow and spatial needs:

• 110x54mm – Popular for bathroom fan vents
• 150x70mm, 180x90mm – Medium flow, compact installations
• 204x60mm, 220x90mm – High-capacity airflow with a low profile
• 234x29mm, 310x29mm – Ultra-slim options for shallow spaces

Each size comes with connectors, elbows, end caps, reducers, and more, ensuring seamless joins and optimal system integrity.

All Types of Fittings & Accessories

In addition to ducting lengths, we stock a full range of accessories to complete your system:

• Adaptors, reducers, and connectors
• Ceiling vents, grilles, spigot plates
• Fire-rated ducting options for compliance
• Condensation traps, silencers, and clips
• Flexible hoses, wall plates, and tapes

No matter your project size, we can support you with complete ducting kits or individual components tailored to your layout.
