Standard Size
Diameter: 150mm (6 inches) – Compatible with most standard exhaust fans, kitchen hoods, HVAC, and ventilation systems.
Length: 6 meters – Long enough for extended ducting needs; can be cut to size.
Highly Flexible
The duct can bend and curve around obstacles, making it ideal for tight or awkward installation spaces.
Perfect for DIY or professional use in renovations and new builds.
Multi-Layer Construction
Typically made with multiple layers of aluminium foil and polyester laminate wrapped around a spiral wire frame for added strength and shape retention.
Some models may also feature fiberglass insulation to reduce heat loss and noise.
Heat and Fire Resistant
Designed to withstand high temperatures, usually ranging from -30°C to +110°C (depending on brand).
Many comply with fire safety standards such as BS 476 Part 6, 7, 20 or AS/NZS 4254.
Tear-Resistant & Durable
Reinforced layers offer resistance to punctures, tears, and wear-and-tear from repeated flexing.
Lightweight and Easy to Handle
Easy to carry, cut, and install – even in overhead or tight spaces.
Corrosion & Moisture Resistant
Aluminium layers resist corrosion from humidity and airborne chemicals—especially important for kitchen or bathroom exhaust.
Low Air Resistance
Smooth inner surface reduces drag and turbulence, supporting efficient airflow through the duct system.
Compatible With Most Ventilation Systems
Works with kitchen chimneys, range hoods, exhaust fans, bathroom ventilators, and HVAC ducts.
Connects easily to round or oval duct connectors.
Compressible for Easy Storage & Transport
Supplied in a compressed form (typically around 60 cm) and can be stretched to full length (6 meters) during installation.
