In addition to floorboards, there are also wooden click tiles for the terrace. Compared to planks, they can be installed very easily and quickly (and are also suitable for small city balconies). You do not need a wooden substructure for this, just a level surface.
Local woods that are suitable for the terrace:
- Douglas fir (originally from North America, but now also grows here)
- Sweet chestnut
Larch and Douglas fir wood should be treated against blue stain and rot before installation, as they are susceptible to fungal attack. Otherwise, the best thing to do is to oil the wood after laying your real wood planks for the terrace. There are special terrace oils that are hard-wearing and cannot be rubbed off by using the terraces. These oils penetrate deep into the wood and form a protective film with pigments and natural resins.
Decking boards made of teak or coumarú do not need to be treated with a wood preservative and will take on a silver-grey patina over time if left untreated (see picture). If you do not like this, you should treat the wood with special oil to maintain the golden brown colour.
- Thermally modified woods: heat-treated wood that lasts longer. Ash and pine, in particular, like to be thermally treated and then turn into thermal ash and thermal pine.
- Chemically modified woods: These woods, e.g. B. Accoya wood, are soaked in acetic acid (acetylation) or furfur alcohol (furfurylation), are resistant to pests and fungi and hardly absorb any water.
- Water-repellent woods: By soaking the wood in paraffin or other water-repellent materials, the lifespan of these woods is increased outdoors.
