Blauberg SonoFlex 150mm Insulated Flexible Ducting 10m | SONOFLEX-150-10

150mm Insulated Flexible Duct with 25mm Rockwool Insulation

The Blauberg SonoFlex 150mm Insulated Flexible Ducting is a high-performance flexible ventilation duct designed to provide improved thermal insulation, condensation protection and acoustic performance in domestic and light commercial ventilation systems.

Supplied in a practical 10 metre length, SonoFlex combines a flexible aluminium inner duct with 25mm Rockwool insulation and a metallic silver aluminium laminate outer jacket. This insulated construction makes it particularly suitable for ductwork passing through cold or unheated areas, including lofts, roof voids, ceiling spaces and garages.

With a nominal 150mm / 6" diameter, the SonoFlex-150-10 is suitable for use with compatible bathroom extractor fans, inline fans, MEV, dMEV, MVHR and HVAC systems.

Thermal & Condensation Protection

Ventilation systems frequently carry warm, moisture-laden air from bathrooms, shower rooms and other wet areas. When this air travels through ductwork located in a cold loft or roof space, its temperature can fall rapidly, increasing the risk of condensation.

The 25mm Rockwool insulation surrounding the SonoFlex duct helps limit this temperature change and provides improved thermal protection compared with standard non-insulated flexible ducting.

This makes SonoFlex particularly useful for extractor fan installations where the duct route passes through unheated parts of a building.

25mm Rockwool Insulation

The SonoFlex-150-10 features 25mm thick Rockwool insulation with a stated thermal conductivity of ≤0.04 W/mK.

This insulation helps reduce unwanted heat transfer between the air travelling through the duct and its surrounding environment, providing additional protection for ventilation runs in colder areas.

Acoustic Insulation

As well as providing thermal insulation, the Rockwool construction can help soften duct-borne noise and vibration generated by fans and moving air.

This can be particularly beneficial for ventilation ductwork running close to bedrooms, living areas, offices and other noise-sensitive spaces.

Flexible Installation

The flexible construction makes SonoFlex suitable for installations where rigid ducting would be difficult to route.

It can be used for final connections, awkward duct routes and ventilation runs through lofts and ceiling voids. Care should be taken during installation to avoid excessive bends, compression or crushing that could restrict airflow.

Why Choose Blauberg SonoFlex?

Choosing an extractor fan is only one part of creating an effective ventilation system. The ductwork can also influence airflow, condensation risk, heat transfer and noise.

The Blauberg SonoFlex-150-10 provides a practical upgrade over standard uninsulated flexible ducting when a duct route passes through colder or noise-sensitive areas. Its combination of 25mm Rockwool insulation, flexible construction and 10 metre length makes it particularly well suited to bathroom ventilation, loft installations and residential ventilation systems.

For best performance, ducting should be installed in accordance with the ventilation system design, applicable Building Regulations and manufacturer instructions.
