Foam Ducting (Aerfoam)

MVHR units will require servicing , the replacing of the internal filters is only part of what should be covered within a unit service, ideally the MVHR should have the Heat Exchanger removed and the unit cleaned internally , the condensate drain should be checked for signs of leaks and blockages, the ducting should be checked and cleaned where possible, the ceiling valves should be removed and cleaned and if required the system should be re commissioned and balanced .

No, you do not need adhesive for foam ducting, it should be supplied with connectors and joiners, these are easy to use, quick to install and when clipped together ensure an airtight seal.

Aerfoam (Foam ducting) meets all the ventilation requirements in relation to insulation levels , therefore stopping condensation build up.
 

Wall Brackets should be placed every 500 mm to support the Foam ducting (Aerfoam).
 

Aerofam (Foam Ducting) is installed by sliding onto the spiggot and connecting with a suitable aerfoam connector.
 

Aerfaom needs no maintenance.
 

Aerfoam can be recycled.
 

Aerfoam is a mass flow insulated duct and can be used in all unheated areas to comply with Doc F, it is low in air resistance and produces superior airtightness and insulation levels. Take a look at our blog and the benefits of Aerfoam.
 

Foam vent ducts and foam duct insulation are used primarily to prevent condensation (sweating), improve energy efficiency, and reduce noise in HVAC and ventilation systems. They are especially effective in unconditioned spaces like attics, basements, or crawlspaces where extreme temperature differences cause metal ducts to sweat. 
Key Advantages
•    Condensation Control: Closed-cell foam (such as polyethylene or synthetic rubber) prevents moisture from forming on the cold metal surface of the duct. This reduces the risk of mold and mildew.
•    Energy Efficiency & Thermal Resistance: Foam provides excellent insulation, reducing thermal loss by up to 30%. This helps keep air at the desired temperature, improving MVHR system performance.
•    Sound Absorption: The flexible nature of foam helps mute the noise of airflow and vibrations within the ducting, creating a quieter environment.
•    Ease of Installation: Foam insulation is lightweight, easy to cut, and flexible enough to conform to corners and bends.
•    Durability and Moisture Resistance: Foam is typically resistant to bacteria and mold, making it suitable for long-term use in damp areas.

Ducting, is defined as a series of either flexible,  rigid or semi rigid tubing that will allow air to pass through. Ducting can come in multiple shapes, sizes and materials a ducting calculation must be done to ensure suitable air flows can be achieved  for your home/project.

Aerfoam / foam ducting is easier to assemble, its easier to cut and has more sound attenuation than metal duct, and Ubbinks Aerfoam duct is already pre insulated so no extra work wrapping the duct.

Yes, using foam ducting will save time, Foam Ducting systems can be assembled in minutes rather than hours, no sealing, no taping and one key benefit is that its already pre insulated so no wrapping in foil to prevent condensation forming.
