The carbonized wood surface offers natural protection against fungi, mould, rot, insects, rainwater, wind and weather. Even without additional treatment, carbonized timber facades are resistant to the effects of the weather. This makes subsequent treatment with chemical wood preservatives superfluous!
In contrast to conventional wooden facades, which discolour or crumble in places over time due to increased exposure to sunlight, rain or other weather influences, wooden façades carbonized with Shou Sugi Ban transform much more slowly and as a whole. Only the overall appearance of the carbonized wood cladding changes slightly over the years, depending on the type of finish.
Black carbonized walls, for example, take on a silvery sheen over time. The result is a new, unique look that does not require regular maintenance or re-treatment – unlike glazed or painted wooden facades, which need to be repainted every few years.
