Can polyethylene foam reduce noise or vibration? Is Isolon/Warmlex suitable for acoustic insulation?

Isolon and Warmlex foams reduce vibration and structure-borne noise due to their elastic closed-cell structure. They are widely used for vibration damping, cushioning and reducing impact sound.

Polyethylene foam is not a substitute for specialised soundproofing panels, but it is an effective material for vibration damping, reducing impact noise and minimising resonance in technical systems.

How vibration damping works

Both IXPE/XPE (Isolon) and non-crosslinked PE (Warmlex) have an elastic and resilient structure that:

• absorbs mechanical shock or impact;
• reduces transmitted vibration between surfaces;
• helps stabilise equipment, flooring or metal constructions;
• minimises resonance in machinery or joint areas.

Common applications

PE foam is commonly used in:

— HVAC vibration and contact insulation;
— packaging of equipment and electronics;
— machinery supports and anti-vibration pads;
— expansion joints and connections in buildings;
— automotive components and gaskets.

Impact noise vs airborne noise

Polyethylene foams are most effective against:

• impact noise (steps, movement, vibration);
• structure-borne vibration.

For airborne noise (voices, music) a dedicated acoustic system may be required.

Frequently asked questions

• Is this material suitable under flooring? Yes, it reduces impact noise. Correct installation is key.
• Can it replace professional acoustic panels? Not fully. It is effective against vibration and impact noise, but not a universal solution.
