Frequently asked questions: 

Can you lay wooden floors on floor heating systems?

All tilo flooring products are generally released for installation on floor heating systems.

However, the existing heating system should be temperature-controlled to guarantee that the prescribed max. allowed surface temperature according to the installation instructions is not exceeded on the free surface of the floor area.


How much waste can you expect from an installation of a floor?

This depends on the type of installation and the given space situation. If a continuous installation is carried out, i.e. the second installation row is started with the remaining pieces from the first row, you can expect hardly any or only a minimal amount of waste.


Which tilo floors should I choose in case of allergies?

Since allergies can be triggered by various substances which are not usually considered a risk to health, we recommend taking a sample piece and testing whether touching the desired product causes allergic reactions.



Should old coatings be removed before the installation?

It is strictly required to remove carpets for technical as well as hygienic reasons.

To what extent PVC coatings must be removed depends on the respective situation and the available product. Your trusted specialist retailer can advise you on this in detail.

Do tilo products contain formaldehyde?

We confirm that natural floors by tilo do not have any adverse effects on health whatsoever. The formaldehyde content in the finished product is under the legally prescribed limit of 0.1 ppm. No solvents, heavy metals, tin, MDI, TDI, halogens or any other harmful substances are used for production.


Can I lay wooden floors in damp rooms?

Generally speaking, wooden floors are only suitable for installation in dry rooms. Due to its unique combination of thermal treatment and Natwood, the product Inline Solid Wood Parquet Natwood in the wood type Ash Mocha is released for laying in damp rooms by the company tilo.


How often can you sand wooden floors?

With a wear layer thickness of approx. 3.5 mm and an average layer loss of approx. 0.5-0.7 mm per sanding, the area can be sanded three times.


What do technical terms such as: Brinell hardness, ambient noise, exposure to moisture, thermal conductivity and thermal insulation resistance mean? 

Acoustic behaviour

Here we first need to distinguish between ambience and footfall sound: ambience noise is in the same room, whereas footfall sound is heard in rooms which are below or adjacent. A full-surface bonding of parquet floors significantly improves the ambience noise value compared to a floating installation.


Brinell hardness

The hardness level of a wood type is an important indication of the wear and indentation resistance you can expect from it.

Brinell hardness comparison

Wood hardness can be determined with the Brinell test. Here a 10 mm-diameter steel sphere is pressed with a defined force against the wooden surface for a given period of time. The sphere is then drawn back after the load time has passed. Brinell hardness can be calculated from the surface of the indentation and the compression force. The higher the measurement of Brinell hardness, the harder the wood is. However, indicated hardness levels must always be understood as average values, since the actual values vary a little depending on the growing area of the tree and the cut type (all woods are harder when cut along the grain rather than across the grain).


Colour changes by light exposure

Chemical reactions in the wood substance triggered by daylight cause changes in colour. This natural alteration happens in the first period especially and testifies to the authenticity of the natural product.


Exposure to moisture

When exposed to moisture, wood reacts by swelling and shrinking. An installation on PE film does not provide absolute sealing from below. A dry ground is therefore always required. In any event, standing moisture should be avoided, also from above.


Glueless floating installation

In case of floors exposed to high stresses, floor heating, installation in larger rooms and long-term installation, we recommend additional gluing of the upper edge inside the groove-shaped slot. Length-side gluing is also possible.

Always lay a PE film which is at least 0.2 mm thick, vapour-sealing and rot-proof under tilo floors. This film is used to protect against moisture and especially creates a slidable level to ensure that the floor can float freely.


Renovation options

Parquet floors can be renovated after heavy use, even after decades. Surface sanding, new sealing and oils or waxes restore your floor to mint condition.



Sawn timber is also differentiated according to the position of the growth rings.

Riftware (rift cut/ radial cut) means that there are predominantly standing growth rings, i.e. the growth rings appear on the broadside of a board as fine parallel stripes. Wood which has been cut this way retains its dimensions better than woods with lying growth rings. In practice, you can find not only standing or lying growth rings, but also diagonal ones, which are called semi-rift.


Full-surface bonding with glues

tilo floors can also be glued firmly to the ground. For this, use tilo adhesive systems. Before starting the installation work, it must be checked that the subfloor is suitable for flooring (DIN 18356 “Parquet work”) and that the prescribed requirements are met.

Reference for glues: use the products from the tilo glue range. In any event, please observe the processing specifications on the packaging or the respective manufacturer information. If you have any construction suggestions or any questions, please contact the tilo service team.


Living environment

Floor coverings made of wood, wood-based materials, cork or linoleum are ideal for your well-being and for structural physics. A healthy indoor climate helps to preserve the value of the floor and at the same time is important for people’s general well-being. The relative humidity should be between 40 and 60%. You can prevent the air from being too dry by using humidifiers and setting up indoor plants. Hygrometers and thermometers help to control it.


Thermal conductivity

Wooden floors are perceived as warm underfoot due to their very low thermal conductivity.


Thermal insulation resistance

Thermal insulation resistance indicates the insulation value of a material. The basis is the thermal conductivity parameter with which the thickness is considered. In case of floor heating, thermal insulation resistance for all layers above the heating level may not be higher than 0.15 m2 K/W, otherwise thermal heat cannot be emitted sufficiently into the room. However, it is negligible if it exceeds the limit by a minimum.
