Most of the terraces are covered with slabs or frost-proof tiles. Many builders prefer these materials because they are weather-resistant and also easy to clean. However, they give themselves the opportunity to bring the naturalness of the building material wood on their terrace.
It is certainly true that every wood is susceptible to the effects of the weather and also to the UV rays of sunlight. Therefore, it is important to follow a number of basic rules if the deck is to be fitted with a wooden decking. The most important of these rules is to provide adequate ventilation of the wood. If moisture can accumulate in the joints between the woods, this rule was ignored and soon irreparable putrefaction will set in. Therefore, the laying of a wooden floor on the terrace begins at the base.
What are the possibilities of a wooden terrace floor?
A permanently mounted wooden terrace floor consists of a load-bearing base on which counter battens are applied. It serves to receive the boards of the deck covering and at the same time to ventilate the underside thereof.
A second possibility is to screw these boards in individual segments on a battens. These segments are evenly divided according to the size of the terrace. The advantage of these segments is that they can be stored during the season, in which the terrace can not be used anyway.
A third option is wood tiles. The building materials trade and also some furniture stores lead these in different variants. They are predominantly square and equipped with a base made of wooden strips or a plastic grid. Particularly convenient is the solution in which these substructures of the individual tiles are interlocked or clicked together when laying. Wood tiles are also preferably stored dry when not needed.
How is a fixed wooden floor made?
Decisive is first the underground. A plate pavement laid in the gravel bed always carries the risk that this structure changes due to subsidence in the soil. Therefore, it is not advisable to equip such a surface with a fixed wooden floor.
If a tile floor is present, whose damaged surface is to be covered with a wood covering, the counter battens can already be dowelled on these tiles. However, a fresh or renovated screed is better in every case. Then a battens is applied, the distances between them must not be greater than 50cm. The decisive factor is the thickness of the deck covering, which must not sag. When drilling the dowel holes for this counter battens, any moisture barrier or thermal barrier coating in the concrete must not be damaged.
Before screwing on the counter battens, a bituminous membrane (roofing felt) is laid all over the substrate. Better, but only with expertise to realize, is the use of a bitumen welding line. When the battens are completely screwed on, this subfloor will be completely covered with a bitumen hot-dip.
The decking of hardwood boards is fastened with stainless steel countersunk screws. Between the boards remains an air gap of about 5mm. The conclusion is a glaze or oil coating.
Hardwood boards in segments
In this construction, the area of the terrace is divided into even segments of a maximum of 1.5x1.5 meters. The hardwood boards are cut evenly in the appropriate length and laid with the top down on a level surface and selected at right angles. Their connection is made with 2.5 cm thick wooden strips, which are screwed on at intervals of about 50cm. You always need to use two screws per board to give the segment sufficient stability. The conclusion is an all-round glaze or the use of an appropriate oil. Then the segments can be laid on the ground and removed in the cold season.
Another advantage of this variant is that no screw heads are visible in the deck covering. Important is only when screwing the strips on the back, that screws are used in the maximum possible length, without piercing the top of the boards.
Wooden tiles in different variations
Your installation requires the least effort. The only requirement is a sufficiently stable and even surface. They are placed on this surface or interlocked or clicked into the Klickverbindere. Even with wooden tiles, a final wood protection with glaze or oil is required.
Woods and prices
Boards for patio coverings are made of hardwood or precious woods. Particularly suitable are:
- Douglas fir 1.80 €
- Acacia 4.10 €
- Robinie 4,20 €
- Oak 4,40 €
- Bangkirai 8,50 €
- Massaranduba 4,30 €
The prices for wood tiles vary greatly according to their wood, thickness and connectivity. The prices range from 10.00 to 50.00 € per square meter.
The material wood
Due to its natural properties, wood is an ideal material for the construction of terraces or the design of the floor of balconies. In summer, wood does not heat up as much as stone or ceramic tiles, and in autumn wood is pleasantly warm to the feet.
Wood is very flexible because of its easy processing and high stability with comparatively low weight. Another plus is the natural look. Since most of the terraces and balconies are exposed to the weather, you should use only very robust woods such as oak, robinia, Douglas fir and larch for the construction of a wooden floor covering. These types of wood can be installed untreated, although only the heartwood may be used.
A good alternative for the terrace covering are softwoods which have been pretreated, whereby experts recommend here pressure-impregnated wood. Especially suitable are tropical hardwoods, especially the East Asian Bangkirai wood. It is important to note, however, that tropical woods should have the FSC mark, so you can be sure that it does not come from the depletion. Basically, Bangkirai is not available with the FSC certificate, so that an origin from the depletion can not be excluded.
It is important for a wooden terrace that ensures adequate ventilation and that the rainwater can drain. Therefore, a gravel bed is usually created as the basis for the carrier. The substructure should also have a very slight slope and the joint width between the individual planks should not be less than three millimeters. This is how the wood can work and rainwater can drain off quickly.
Since wood has a high load-bearing capacity, uneven or sloping terrain can be ideally compensated with a suitable support structure. In addition to all these advantages, building owners make their own contribution to climate protection by using wood for the decking. Every cubic meter of wood binds 250 kilograms of carbon, which corresponds to the amount contained in around 900 kilograms of CO2.
