There is also much to tell about the use of wood in the House of Bosch. Earlier, the key pieces were mentioned. These are made of oak. The roof structure of the roof is also made of oak. The rafters used for the roof are from 1463. By making small drill holes and examining the annual rings, we know exactly how old the wood is. The roof was renewed in the year that Jheronimus' father bought it. Could he have rebuilt the house before he moved in with his family?
In the bar in the photo you can see an incised v-shape. This is a raft mark. The wood used to come to our country via the Rhine or Meuse rivers. It came in large quantities at a time by raft. The V-shape is a property mark. This is how the boatmen knew which wood was destined for whom. The oak tree stump in the photo is called a 'rail'. A rail is a fairly thin beam that runs from eaves to ridge. On the 'spur' lie the battens and on top of them the roof tiles. Tracks were later replaced by 'firs'. The name gives it away, these were not made of oak but of pine.
The groove in the wood is from a brace/corb. In the other photo you can clearly see the scratch lines. These lines were made to be able to cut out the groove afterwards. In that groove the 'brace' could be placed. This is an angled beam that supports the beam above it. In order to be able to attach the brace properly, so-called dog nails were used. These were also made of oak.
In the other photo you can clearly see that the floor was also the ceiling of the floor below. The ceiling at that time was green. This is the same color green as one of the key pieces with the acanthus leaf. The floor is from the late 16th century or later. The wooden floor is made of pine. In the course of time, oak wood became more and more expensive because it was widely used for shipbuilding. Therefore, in time, people switched to the cheaper softwood.
