How do EPE ducts differ from EPP ducts?

EPE (Expanded Polyethylene) is a slightly softer and more elastic material than EPP (Expanded Polypropylene), giving these ducts a degree of flexibility. This flexibility becomes a huge advantage when the heat recovery unit is installed in a very tight space and you need to slightly adjust the pipe angle to perfectly align with the hole drilled in the wall for the outdoor grille. While EPP is mechanically more impact-resistant, EPE boasts better sound absorption properties, acting as an additional silencer directly within the trunk line.

Do EPE ducts require additional sound insulation?

No, EPE ducts act as excellent acoustic insulators themselves due to their unique, closed-cell foam structure. They absorb micro-vibrations and low-frequency hum created by the fan motor, preventing it from spreading into building structures or living rooms. Of course, for absolute silence in the rooms, it is still recommended to use main silencers in the supply and extract lines after the heat recovery unit.

How do you securely connect EPE ducts?

EPE ducts are connected using special sleeves made of the same EPE polyethylene, which tightly and hermetically embrace the pipe ends. The installation process requires no glue, silicone, or metal self-tapping screws. The pipe ends are simply pushed firmly into the sleeve, and due to the material's elasticity, the joint locks absolutely airtight. No thermal bridges form at the connection points, ensuring the entire route remains 100% protected against condensation formation.

Heat Recovery Units

Looking for a reliable and installation-friendly insulated duct solution for tight spaces?

EPE (Expanded Polyethylene) ducts combine excellent thermal insulation with outstanding acoustic properties and unique flexibility.

Thanks to their softer structure, they allow for easier maneuvering in utility rooms, perfectly dampen heat recovery unit motor noise, and fully protect against condensation.

The problem of cramped spaces and vibrations

Installing ventilation systems in modern homes often faces a critical lack of space. Heat recovery units are frequently hidden in small corners of utility rooms, above washing machines, or in narrow closets. When trying to connect the unit to the outdoors in such spaces using completely rigid and unyielding pipes, every millimeter becomes a headache. An inaccurately drilled hole in the wall means a rigid pipe simply will not fit, and forcing components together will cause them to lose airtightness.

Rigid trunk lines are also perfect transmitters of mechanical noise. If rock wool-insulated galvanized steel is used for the outdoor exhaust and intake, motor vibrations often travel through the metal itself straight to the external wall. This can create unwanted structural resonance that you will feel on quiet nights, even through the closed door of the utility room.

The soft, flexible, and silent EPE transformation

EPE (Expanded Polyethylene) ducts provide the installer and the homeowner with unique engineering freedom. Because of their inherent elasticity, these insulated pipes can be slightly bent. This means that if the heat recovery unit spigot and the hole in the external wall are misaligned by a few centimeters, the EPE duct can be gently curved to perfectly connect the system without using any additional angular elbows that reduce airflow.

This material acts as a massive sound dampener, absorbing noise. The EPE foam structure is softer than EPP, so it does not transmit motor vibrations. Air travels extremely quietly, and moisture has no chance of penetrating the closed polyethylene pores. You get an absolutely dry, silent, and adaptably flexible trunk line for your ventilation system.

Exceptional sound absorption and flexibility – EPE ducts absorb up to 30% more mechanical vibrations than completely rigid solutions, while simultaneously forgiving minor space planning errors during installation.

When selecting an expanded polyethylene system, it is important to pay attention to several technical parameters that ensure efficiency. These ducts are specially designed for harsh climates and extreme temperature differences:

Internal diameter match (125 mm, 160 mm, 200 mm) - choose an EPE duct whose internal diameter precisely matches your heat recovery unit's connection flanges. This precision is essential to avoid any pressure drops at the very beginning of the route.
Wall thickness (thermal resistance) - the standard wall thickness of EPE ducts is around 15-16 mm. This optimal thickness has a thermal conductivity coefficient that guarantees no condensation will form on the outer duct surface, even when it is -20 °C outside and +22 °C inside.
Elasticity and bend radius - although EPE is not as flexible as a corrugated pipe, a 1-meter section can be safely bent at a slight angle without damaging its internal structure. This helps bypass minor obstacles (pipes, wires) in the ceiling.
Material density (kg/m3) - EPE polyethylene is exceptionally lightweight (around 30 kg/m3), meaning it puts absolutely no strain on your suspended ceilings or plasterboard structures, compared to heavy metal and wool-insulated alternatives.

When is it better to choose EPE over EPP?

If your utility room is extremely small and requires complex, tight connections, EPE is the undisputed leader. EPP ducts are excellent where there is plenty of space and the priority is maximum mechanical resistance (e.g., in open industrial spaces). However, in home boiler rooms, where every centimeter is counted and additional acoustic comfort is valued, the softer and more flexible EPE fulfills all expectations.

Tool-free connection process

Expanded polyethylene ducts are installed faster than any other ventilation system on the market. Their light weight and inherent elasticity allow the work to be done even by one person, without the use of any dangerous cutting tools.

Quick cutting - an EPE duct can be cut to the required length with a simple utility knife or a fine-toothed hand saw. The material does not crumble, leaving no sharp edges or microplastic dust in the air.
Connection with special sleeves - after cutting the required length, an EPE sleeve is simply pushed onto the pipe end. The material gently adapts to itself, creating a perfectly airtight joint that maintains uniform thermal resistance without any additional sealant.
Changing direction - if a turn angle greater than the material's flexibility is needed, standard 45° or 90° EPE elbows are used, connected using the same push-fit principle.
Fixing to walls - due to its extremely low weight and vibration-dampening properties, it is sufficient to lightly secure the route with standard plastic or metal duct clamps, being careful not to over-compress the insulation itself.

A worry-free, long-lasting system

EPE insulated ducts are resistant to aging and require no additional maintenance. Closed-cell polyethylene does not absorb water even when submerged, so it will never rot or change its insulating properties for decades. By installing this line from the heat recovery unit to the exterior facade, you get a safe, dry, and insulated air channel for the entire life cycle of the building.
