KERMI HRV Insulated Ducts – Quiet and Efficient Ventilation

KERMI HRV insulated ducts are an innovative solution for building ventilation systems in homes, providing not only effective air exchange but also high acoustic and thermal comfort. Designed for connecting the HRV unit to air intakes/outlets and distributors, they are an integral part of the KERMI SILENT VENTILATION system. Their construction and materials minimize energy losses and reduce noise, resulting in better air quality and quieter operation of the entire installation.

Construction and Properties

HRV ducts are characterized by a layered construction. The outer protective tube is made of durable HDPE plastic, while the inner layer is closed-cell polyolefin foam. This selection of materials provides excellent thermal insulation, preventing condensation of water vapor on the surface of the ducts – particularly important for connections between the HRV unit and elements led outside the building. The polyolefin foam effectively dampens the sounds generated by the HRV fan, eliminating the need for additional acoustic silencers. The specific inner surface of the ducts further improves the damping properties.

The installation of HRV ducts is simple and quick – sections are connected using system connectors with EPDM (synthetic rubber with high durability and flexibility). This connection is tight and resistant to damage, while also allowing easy disassembly of the ducts for cleaning or maintenance without the need to interfere with the building structure. This is particularly important for long-term maintenance of high air quality indoors.

Advantages of using KERMI HRV ducts

• Noise reduction: Polyolefin foam effectively dampens the sounds of the HRV fan, ensuring quiet operation of the ventilation system.
• Thermal insulation: The layered construction minimizes heat loss and prevents condensation of water vapor, resulting in energy savings and user comfort.
• Easy installation and disassembly: The EPDM connector system enables quick and trouble-free installation and disassembly of the ducts for cleaning or maintenance.
• Durability and tightness: High-quality materials guarantee long-term operation and tight connections.
• Easy cleaning: The possibility of disassembly facilitates regular cleaning of the ducts, ensuring hygiene of the air in the rooms.
• Flexibility: EPDM connectors provide flexibility of connections, making it easier to adapt to the existing installation.

KERMI HRV ducts are an ideal solution for both professional installers and end-users looking for an efficient, quiet and durable ventilation system. They provide a comfortable indoor climate and contribute to improving the quality of life.
