Rubber cork material

From flooring to technical components, the demands are rising — and standard materials seem to be no longer up to the job. Constant damage, leaks, slipping parts and repeated replacements. And you’re not doing this just to be back fixing everything again in a few months’ time. Interestingly, the root cause rarely lies in the design itself. Is the floor creaking? Are the seals wearing out too quickly? More often than not, the issue is the material rather than the installation. In situations like these, Rubber Cork performs exceptionally well. It’s a material for those looking for a durable, proven solution for demanding applications — including technical and industrial environments.

What’s worth knowing about rubber cork?

WHAT IS RUBBER CORK?

Rubber cork is a composite material that combines natural cork with rubber. It is made from cork granules and rubber bonded together with a polyurethane adhesive. It is neither pure cork nor pure rubber. Instead, it sits somewhere in between — engineered to solve specific problems where cork or rubber alone simply won’t do the job.

Rubber cork is available in several formats — including underlays, sheets and rolls — making it easy to match the material to a particular application. Each format addresses a different need, but all are based on the same core material.

WHERE IS RUBBER CORK USED?

Where standard underlays, foams or felt simply can’t withstand the load, lose their properties and quickly become compressed. If, after a year of use, the underlay is flattened and the floor starts to creak, it’s a clear sign the material hasn’t stood the test of time.

The combination of cork and rubber is the right choice if you’re looking for something more durable:

Rubber cork underlays for flooring – protects the floor while improving its stability and comfort underfoot. It performs particularly well beneath floors exposed to heavy, day-to-day use.
Rubber cork sheets for gasket production – allow gaskets to be cut precisely to size. The material conforms well to surfaces and maintains a reliable seal. It is resistant to greases and oils.
Rubber cork in rolls for bespoke gasket manufacturing – ideal for longer or non-standard gaskets where material continuity is essential.
Rubber cork coverings for machine rollers – used in winding, slitting, printing, flexographic, rewinding and laminating machines, among others.

When might rubber cork not be the best option?

If you’re simply looking for the cheapest possible underlay for short-term use.
In cases of light loads and standard residential conditions, cork on its own is usually sufficient.

In such situations, rubber cork would simply be an unnecessary expense.

WHEN DOES RUBBER CORK UNDERLAY MAKE SENSE?

It’s a good choice if:

the floor is heavily used (e.g. in a living room, hallway or public space) and you want the underlay to retain its shape over time,
you’re looking for a long-term solution rather than the cheapest short-term fix,
you want a floor that feels warm underfoot, reduces noise and offers everyday comfort.

CORK OR RUBBER CORK – WHICH SHOULD I CHOOSE?

The right choice depends on the type of floor covering, acoustic requirements, moisture levels, point loads and whether underfloor heating is involved. In many homes, cork on its own is perfectly sufficient — particularly where the subfloor is not exposed to heavy use. It works especially well beneath floating floors. Rubber cork, however, is the better option in more demanding conditions. It absorbs pressure, dampens vibrations and retains its properties where other materials tend to wear out quickly.

Rubber cork combines the benefits of natural cork and rubber in a single solution. As a result, it is flexible, durable and highly practical at the same time. When properly installed, rubber cork is resistant to cracking and crumbling, and under normal conditions its lifespan is measured in years. You won’t need to replace it after just one year. It performs equally well beneath flooring, in gaskets, machine components and technical coverings.

Rubber cork brings together many of the advantages of foam, felt and rubber, while minimising their typical drawbacks. Foam is inexpensive, but it compresses quickly and, over time, stops doing its job properly. Felt is soft and pleasant to the touch, yet it doesn’t cope well with moisture. Rubber on its own is durable, but it lacks the distinctive properties that cork provides. Rubber cork strikes a very sensible balance — durable, practical and reliable for everyday use.

It’s also worth noting that rubber cork contains natural cork — a renewable raw material harvested without cutting down trees. The bark regenerates naturally, meaning its use does not lead to deforestation. In practical terms, this translates into reduced reliance on non-renewable resources and a lower environmental impact compared with many conventional plastics. All while maintaining the performance standards required for technical applications.
