After charring and brushing, Sakaide is treated with our Bito Clear or Bito Orange.Bito Clear is a transparent oil for interior applications. The oil hardens und... More

The durability of Douglas wood is Class 3 and is therefore very suitable for use as wall cladding. Characteristic of... More

The carbon stains somewhat, but it does not wash out when it rains. The brittle coal layer requires a specific detailing of the building to reduce the influence of wind and weather. We recommend that this type not be used above a height of 6 metres above ground l... More
