Decking boards and installation

Environmentally resistant material

The natural surface is warm and pleasant underfoot!

The wooden floor has a beautiful appearance, is warm and makes the indoor climate of the living room pleasant. These qualities apply not only to indoor spaces, but to the same extent outdoors.

Whether it is a new construction or the repair of an existing outdoor facility, everywhere you can use wood to achieve outstanding results in design!

Balconies, terraces, curbs, sidewalks, bridges...there are many areas of use for hardwood decking. The common feature of all non-utilities is that the surface covered with hardwood boards is pleasant underfoot. The pleasant sound of walking and the harmonious natural look always put you in a good mood. One advantage of wood is pleasantly felt on a wooden surface, which often goes unnoticed: wood does not get as hot in the summer as other materials (such as stone and metal) and does not cool down as much in the winter.

Due to its long life, 1st and 2nd durability class hardwood has become the preferred material for designing outdoor facilities. The diverse properties of different types of wood allow you to choose a suitable and functional construction for almost any purpose. Whether you are an architect, planner, craftsman or builder, durable hardwood offers numerous advantages for everyone:

wood is a proven material that has significant ecological advantages compared to other materials; the wood resource is renewable, its production does not require the use of toxic chemicals or primary energy sources (such as for PVC, aluminum, etc.)
wood can be processed very well and thus economically
Durability class 1 and 2 hardwood is very durable even without impregnation agents that burden the environment
due to its high density, hardwood is relatively less susceptible to external mechanical influences
structural and formal diversity offers great opportunities for different design techniques

PINE, LARCH, BANGKIRAI ... WAS THERE NO BETTER MATERIAL?

Currently, wooden terraces, balconies, bridges, porches, facades and other structures are in fashion. Domestic wood species are not durable enough for such purposes, so they need to be impregnated if used outside. Impregnation can be done simply by overwetting with a wood preservative or by pressure impregnation. In the case of most types of wood, however, only the sapwood penetrates, as the impregnating agent penetrates the softwood only superficially. Full impregnation is technically not possible in most cases, so sooner or later the effects of the weather reach the unprotected wood layer through the cracks. Wood, which is naturally low in durability, opens up a wide field of activity for wood fungi and insects, as a result of which the wood begins to rot. The repair of wooden parts damaged in this way is associated with high costs, especially due to the expensive waste treatment, since wood impregnated with wood preservatives is classified as special waste.

However, nature offers an alternative: hardwood with high resistance to wood-decomposing organisms. We specialize in the import of such durable, heavy hardwood species, paying special attention to the ecologically controlled origin of the wood and advising clients in both the planning and implementation phases of projects.

Most consumers are probably familiar with Bangkirai, a very common "fashion wood" on the German market. It is certainly less known that the term Bangkirai refers to different types of wood, the resistance of which can fluctuate within large limits (resistance class 1 - 4). Many types of wood we import are much better than Bangkirai.

As an example, we compare Bangkirai with the South American wood species in our selection such as Ipé, Cumarú and Itaúba:

Ipé, Cumarú and Itaúba

has justified itself in many cases in the construction of terraces and balconies. Neighboring countries like the Netherlands and Belgium have a wealth of experience in this area as they have long used tropical hardwoods for outdoor projects.
is available with FSC certification, while Bangkirai is not yet
creasing and warping is less than Bangkirail
are very easy to process
belong to the 1st or 1st - 2nd resistance class, as Bangkirai is located in the 2nd - 3rd class and can even fluctuate between 1st and 4th class depending on the species and the place of growth. In the case of Bangkirai, we are dealing with different types of wood, not a separate species, which also results in significant differences in the properties of the wood. However, Ipé, Cumarú and Itaúba are extremely weatherproof with more uniform properties
there is almost no sap flow, while in Bangkirai hard-to-remove stains have already been observed on facades and concrete surfaces due to the leaching of wood components
is also available as lumber, unlike Bangkirai, while Bangkirai is not due to export restrictions in the countries of origin. Therefore, we can fulfill special orders (special sizes and profiles, etc.) for Ipé, Cumarú and Itaúba and respond more flexibly to customer requests.
there are no characteristic and unavoidable breeding holes for Bangkirai.

Take advantage of our experience and help to improve your quality of life, because our motto is innovation, efficiency, reliability and flexibility.

¹ - depending on the species

Of course! The table given here according to DIN-EN 350-2 is valid for use in hazard class 4 (continuous contact with soil or fresh water). The base values are primarily intended to make it possible to compare the life expectancy of different types of wood. After all, wood is a natural material! In the case of natural materials, the properties always fluctuate, even within a single species. We cannot give any guarantee on the actual life of the wood, as the expected life depends on the conditions of use and the fluctuation of natural properties, which depend on the will of mother nature. The information given here about the expected life is intended, among other things, to indicate that the life of wood can be significantly extended by protecting the structure from moisture. Even the life of an unprotected wooden structure can fluctuate considerably depending on the surrounding humidity, climatic conditions and existing microorganisms. In favorable conditions (for example, without contact with the soil), wood can last significantly longer.

FSC quality mark: As an importer of Brazilian hardwood, Kay Pannier GmbH pays attention to the fact that the wood comes from sustainable forestry. For us, operating according to the strict FSC (Forest Management Council) regulations is self-evident.

Our course is determined by the motto "Build and preserve", based on which we constantly keep in mind the requirements of the healthy future of our forests in our daily work. That it is not just words is guaranteed by the unique, worldwide operating, socially recognized and well-known environmental organizations such as WWF, Greenpeace, BUND, NABU and others. FSC quality certificate supported by More and more hectares of natural tropical rainforests are being managed according to FSC regulations. The consequence of sustainable forestry is not only the preservation of the ecosystem, but also an increase in the standard of living of the local population. More information can be found in our FSC brochure.

Translation of the FSC label: “ Forest Stewardship Council AC * Trademark since 1996; By using FSC-certified wood, we support better management of the world's forests. * FSC certified company * SCS COC-00552 ”

Diversity: Tropical forests are heterogeneous, i.e. they are mixed forests consisting of many different tree species. According to the FSC criteria, the species richness of the forest must be reflected in deforestation. That is why many different types of trees are felled every year in the FSC forests where our wood comes from. Therefore, the types and quantities available also vary by season. We recommend that when planning the use of FSC products in projects, you should consider the characteristics of the wood, so that, if necessary, it is possible to choose the appropriate profile from among the currently available wood species. The types of wood that are well suited for terrace covering are described above with the most important technical data.

Please note:

Wood is a natural product, which is why differences can occur even within one tree species (for example, in structure and color). Untreated wood exposed to the weather acquires a silver gray patina over time. It is a natural process that every type of wood undergoes in outdoor conditions. If desired, hardwood can be treated with finishing materials that slow down or prevent graying.

ASSEMBLY AND MAINTENANCE

There are no product standards or processing guidelines in the form of DIN or EN standards for ribbed boards, balcony and terrace coverings. To enjoy your construction for many years, pay attention to the following construction and use recommendations:

the base surface must be sufficiently stable, flat and load-bearing. When building on top of loose soil, a black weed mat can be applied to prevent weed growth.
The base structure must be strong enough to withstand the natural tendency of the cover boards to move (warping, expansion, shrinkage) and to allow the screwing in of sufficiently large screws.
Hardwood floors must be built on a substructure made of hardwood with the same or similar properties as possible. For example, pressure-impregnated pine substructures often cannot withstand the impact of hardwood decking, meaning screws can come out of the substructure.
The distance between the beams should not exceed 40 - 90 cm, depending on the thickness of the boards: with a smaller distance, it is possible to balance the movement caused by the expansion and contraction of individual boards, the surface remains as flat as possible, and raised board edges do not stick to the legs. In order to drain the water, the boards must be installed at a slight angle towards the profile (this is not necessarily required for hard wood of the 1st durability class).

Recommendation:

Thickness of planks mm	Beam distance in cm	The size of the screws in mm
25 mm	40 cm	5x60
38 mm	60 cm	6 x 90
45 mm	70 cm	6 x 120
60 mm	90 cm	6 x 160

Each board must be attached to the substructure with at least two stainless screws located next to each other (drill a hole in advance!) The screws must be 2.5 - 3 thicker than the board. The distance of the screws from the end of the table should be about 10 cm.
We recommend installing hardwood boards with a distance of 3 - 5 mm. When playing under the influence of humidity, the boards shrink mainly in width, so the gaps become larger.
The ends of the boards are treated with wax or paraffin solution at the factory to prevent cracks. When cutting to size, the cut surface can be covered with a suitable weatherproofing agent (for example, paraffin).
Many hardwood species may experience leaching of wood components (e.g. by rain). Therefore, care must be taken to drain the water (for example with a gutter), especially if the surrounding elements can come into contact with water (as in the case of balconies, roof terraces, etc.). Otherwise, in addition to wood components, unpleasant stains can also occur as a result of dissolved soil dirt (for example, on facades, steel structures, etc.).
To prevent playing due to the seasons, the surface can be treated with some water-repellent agent (for example, an oil suitable for hardwood). Such tools also slow down the natural graying process, during which the wood becomes covered with a silver-gray patina over time. Hardwood species of durability class 1 can be used outdoors without a cover.
Puddles must always be avoided. This applies to wood support points as well as bases for flower pots, sun umbrellas and other flat objects. In addition, as needed, the surface must be thoroughly wiped with a hard brush several times a year or carefully and evenly washed with a high-pressure washer (without chemicals), in which case a test wash must be done on the previously hidden surface.

Typical properties of natural material and features of the wood species are (so there are no errors):

graying of the surface
the tendency of boards to warp as a result of alternating twist growth
the appearance of cracks on the surface and ends of the boards as a result of the natural expansion and contraction of the wood
bumpy places as a result of growth anomalies
occasional flight holes caused by insects that only nest in living wood
natural color differences and changes in wood (for example, reactive changes caused by wood components).
