Rubber cork underlay

This underlay can be used beneath:

• laminate flooring,
• carpet,
• parquet,
• wood boards,
• linoleum,
• PVC flooring,
• ceramic tiles,
• stone,
• cork flooring.

It’s used wherever the floor needs to be stable, quiet, warm underfoot and durable to everyday wear and tear. Whether in residential properties or commercial premises.

It’s an excellent choice for high-traffic areas such as hallways, open-plan living spaces, offices, consulting rooms, receptions, shops and service premises.

Thanks to its higher density (approx. 650 kg/m³), it doesn’t compress easily under load and retains its shape over time. Rubber cork is available in a range of thicknesses (up to 10 mm), allowing it to be matched to the type of flooring and the expected level of use.

When might another solution be a better option?

• if the subfloor is highly uneven (rubber cork is not a levelling compound),
• if you have electric underfloor heating,
• if your only priority is the lowest possible price,
• if the floor won’t be subject to heavy use (in that case, traditional cork will be perfectly sufficient).

Foam may be cheaper, but it’s also softer, which means it compresses more easily under load. As a result, the floor can quickly lose its stability and durability. With heavily used floors, this kind of saving often turns out to be a false economy. Most low-density underlays perform well only at the beginning.

Rubber cork, with a density of around 650 kg/m³, doesn’t compress nearly as easily. It absorbs vibrations far more effectively and provides greater overall stability. If you don’t want to be revisiting your flooring in two or three years’ time and would rather get it done properly from the outset, this is the solution for you.

Put simply, rubber cork is a reinforced version of traditional cork underlay. It’s made from a blend of cork granules and rubber, which makes it denser, more compact and more durable to load.

Standard cork works well in typical domestic settings — bedrooms, guest rooms or areas with moderate footfall. If that’s what you need, there’s little point in spending extra on rubber cork underlay. However, if your floor is subject to heavy use, rubber cork is the better option.

A thicker rubber cork underlay offers better insulation and greater resistance to load, but not every floor requires it. In some cases, a thinner option will be perfectly sufficient — especially if the subfloor is level and stable.

If your main priority is providing solid support for flooring without raising the floor height, go for a thinner underlay. A thicker version makes sense if you’re looking to improve insulation further or if the floor will be subject to heavier use.

Yes — but with an important distinction. Rubber cork generally works well with water-based underfloor heating systems. Its dense structure helps distribute heat evenly across the surface.

However, we do not recommend using rubber cork with electric underfloor heating. These systems tend to heat up more quickly and in specific areas. A dense underlay can restrict heat transfer into the room, reducing the overall efficiency of the system.
