Thermal insulation (Rʎ )

The right underlay can deliver major improvements to heat insulation where the substrate is cold. It acts as insulation between the top layer and the substrate.

Underfloor heating (Rʎ,B)

In general, laminate, parquet and vinyl floors are suitable for hot-water underfloor heating systems. The underlay needs to offer the lowest possible thermal insulation so that the underfloor heating can work efficiently

Impact sound reduction (IS)

When the sound of footsteps are transmitted into the rooms underneath or adjoining, the result is generally known as impact sound. Laminate underlays in combination with the flooring used can significantly reduce this impact sound.

Reflected walking sound insulation (RWS)

The walking noise that you hear in the same room is known as walking sound. The fact that such noises are relatively loud on hard surfaces is due to the floor itself. But underlay has a noticeable effect in reducing walking sound.

It increases walking comfort

An underlay here increases walking comfort by absorbing impacts. This not only increases the level of comfort, but also reduces the strain on feet and joints.

Load protection (DL, CC, CS)

Daily use exposes floors – and thus also underlays – to heavy wear. This is why laminate underlays must be able to stand up to permanent loads (CC/furniture), dynamic loads (DL/walking) and temporary loads (CS), over their entire useful life. This is the only way to protect a floor – and particularly its connection system – over the long term.

Protection against falling objects (RLB)

Falling objects can irreparably damage the surface of parquet or laminate. That is why the insulating underlay used plays a particularly important role, along with the quality of the flooring itself. These factors both have a significant influence on the height of the fall that can be absorbed without damage.

Protection against unevenness (PC)

To protect the floor mechanically and prevent local separations, it must be possible to even out small, isolated bumps. Otherwise, the floor may be damaged, particularly in transition areas

Preventing the substrate from showing through

When modern designer floor coverings (which are usually thinner than parquet and laminate) are fitted, the right underlay will stop the substrate from showing through. This is known as the ‚telegraphing effect‘

PROTECTS AGAINST DAMAGE IN THE EVENT OF SUBFLOOR IMPERFECTIONS

Protection against residual humidity in the substrate

In new builds in particular, there will often be residual humidity in the mineral substrate. A suitable underlay with an integrated vapour barrier is advisable to prevent damage to the floor.
