Those who opt for parquet as flooring do not only have to think about the type of parquet, whether it should be a solid parquet or a multi-layer parquet. The choice of parquet type also specifies how the parquet should be laid. Solid parquet must be glued, while the plank can also be “floating” during the prefabricated parquet. Of course, the parquet price certainly plays a role in the choice of the product.
When buying parquet, some technical aspects should also be taken into account. For example, not all types of parquet are suitable for underfloor heating. Last but not least, it plays a role in how durable the parquet should be. Because if you live for rent, for example, there should at least be the possibility to remove the parquet without leaving the floor when moving out. Here, when laying the parquet, the “floating laying” is certainly preferable to bonding.
What does a “glued-on installation” mean?
During “glued laying”, the parquet is firmly and permanently connected to the substrate by means of parquet adhesive. When buying parquet, it should be borne in mind that parquet made of solid wood should best be glued to a suitable and flat surface. It is advisable to have this done by the skilled person.
There are good reasons to glue parquet or parquet planks fully and to connect them firmly to the ground. In addition to certain types of parquet that cannot be laid any other way, the gluing of the parquet guarantees above all a high durability. Glued parquet made of solid wood is well renovated and lasts for many decades even in rooms with heavy stress on the flooring. The direct and solid connection of the parquet with the substrate thus stands for a high load-bearing capacity.
What does “floating laying” mean?
In contrast to the glued laying, the individual parquet planks are not connected to the ground, but only to each other during the “floating laying”. The parquet lies unpaved on the ground, so “floats” on this one.
The connection between the individual prefabricated parquet elements varies from manufacturer to manufacturer, but is usually done by simple click systems. For the floating parquet laying, therefore, little craftsmanship is necessary. It also quickly gets its hands on laypeople. Afterwards, the parquet floor can also be entered immediately.
Gluing parquet: What are the advantages and disadvantages?
With the glued parquet, there is no room for movement of the floor and thus a much lower noise load due to impact sound than with the floating laid parquet. The solid connection with the substrate ensures that the glued parquet cannot vibrate. The kicking noises are significantly quieter than with the floating installation, where the floor covering amplifies the sound when it vibrates through steps or movements.
Glued parquet does not tend to joint ingenuity and material fatigue due to its firm connection to the substrate. This means that even under continuous load, hardly any cracks can form into which moisture can penetrate. Glued parquet is generally very durable, which significantly increases the service life of the floor covering. In addition, the parquet can be well renovated during its service life and can also be sanded several times over time if necessary.
Glued parquet requires a higher time required during installation and is therefore also more expensive. In the case of glued parquet, correcting installation errors is very difficult or even impossible, because once glued parquet elements can hardly be loosened and realigned without damage. The parquet is also not immediately accessible after installation, because the adhesive must first harden. This takes at least 12 hours.
When bonding with the substrate, large amounts of adhesive are required. Of course, care should be taken to use an adhesive without a solvent. After the removal of an already glued parquet floor, reuse is no longer possible. The dismantling of the glued parquet can also be quite complex. Accordingly, glued parquet is clearly designed for durability and not for flexibility.
Why glue parquet?
Basically, parquet can be laid floating or glued. Bonding has several advantages. Glued parquet is mainly suitable if a very long-term use is planned. This is because the parquet removal is much more complex with glued parquet. If you live in a rented apartment, you should inform the landlord and ask for permission. When does parquet have to be glued? In any case, if a complicated parquet pattern or a sophisticated parquet type is planned.
The glued laying technique is ideal for an apartment with children or in heavily stressed rooms. In the laying pattern and during the transition to other rooms, in the case of bonding, there is usually no need for expansion joints. Another factor when the question of when to glue parquet is answered positively: It is important to have a glue with “healthy” properties, free of solvents and low in emissions.
Advantages and disadvantages of floating installation
The special advantage of floating installation is that it is very easy and fast to be done by laymen with some skill. The only important thing is that the substrate is flat when laying the parquet. To ensure this, there is, for example, self-running filler. After completion of the laying work, the parquet can be entered immediately and the room can be set up.
Another advantage is the possibility to resume the floating parquet if necessary, to replace it when the taste changes, or to re-lay it elsewhere. Especially if the parquet is to be laid in a rental apartment, the residue-free removal at the time of moving out is an aspect that should be considered before buying. Floating parquet is the flexible solution here.
Floating parquet floors have a lower durability compared to glued parquet floors, as vibrations of the floor ingess cannot be avoided. In the long run, this leads to a higher mechanical load and thus to material fatigue on the element connections. In the course of time, cracks can develop here, through which moisture can penetrate into the wood. Also, floating laid parquet floors are less to be renovated, if they swing e.g. during grinding.
It should be noted that parquet can only be used for floating installation if it has also been designed and designated for this purpose.
The main disadvantage is the impact sound caused by the flooring giving way at each step. As with a soundboard, the sound is amplified by vibrations. A footfall sound insulation must be applied to the ground before the parquet is laid floating in order to reduce this effect. For some prefabricated parquet products, the impact sound insulation is already attached to the individual parquet elements.
Why lay parquet floating?
The floating installation is largely without glue. This means that the full-surface bonding with the substrate is completely dispensed with. Only the individual elements are connected. The work can be done by do-it-yourselfers and talented laymen. If parquet with groove and spring is used, the connecting points can be additionally glued, but this is not absolutely necessary. If you live in a rented apartment or plan to remove or replace the parquet floor after a few years, it is best to lay parquet floating. The floor can be removed relatively easily if necessary. The floating installation is not suitable for solid parquet, this type of parquet must be glued. If, on the other hand, you use multi-layer parquet or prefabricated parquet, you can lay the floor floating. Floating laid parquet is not as durable as glued parquet.
Parquet best glued with underfloor heating
Those who have underfloor heating do not have to do without a parquet floor. However, there are a few things to keep in mind. For example, certain types of wood are less suitable and others are more suitable for laying over underfloor heating. Wood species with unfavorable spring and shrinkage behavior such as beech and maple should be avoided here, while e.g. oak and walnut are suitable.
It is crucial, however, that with underfloor heating the parquet should be glued,because only in this way a good heat transfer is possible. In the case of floating parquet, on the other hand, there is an air layer between the substrate and the parquet, which acts like an insulating layer and impairs the heat transfer.
In which direction should parquet be laid?
There are several criteria for the installation direction. In which direction the parquet is laid, for example, has an influence on the optical effect. You can visually widen or extend the room. For a widening, the rods are laid transversely, for an extension longitudinal. Another point is the incidence of light. If the parquet is to be particularly in the spotlight, it is laid in the direction of view to the window. The incoming light brings out the structure of the wood and the grain well. Parquet, which is laid transversely to the window, has the advantage that irregularities and joints disappear visually.
In very large rooms, even diagonal laying patterns can look very beautiful. However, herringbone patterns should always be laid horizontally or vertically, not diagonally. With checkerboard patterns or other small-format patterns, it doesn’t matter in the parquet in which direction you should move it. Ultimately, the taste of the inhabitants decides. The floor publisher can give advice on how to lay parquet: longitudinal or transverse is always a very personal decision.
Why is a vapour barrier under floating parquet important?
The vapour barrier prevents rising moisture from entering the parquet. Which parquet when a steam barrier is necessary is particularly evident in a new building that has not yet completely dried up. There are several ways to integrate a steam barrier. Why should foil be under the parquet? PE films or foam mats made of polystyrene, which act as a steam brake, are well suited. Natural products are not available for this use case. Combined systems (foil + foam) are also good footfall sound insulation. This should not be dispensed with, because the running noises can be quite loud with a parquet floor.
