Work on the bus goes on.

Taking off the inside panels of the bus.
We spend the weekend working on the bus. After we took off the inside panels, to put insulation in the walls. I was amaze to see that there was so much dust and sand in the walls. I cleaned the dust out using the vacuum cleaner to get the dust and sand out of the walls around the wheel arch. That is when I found that the outside wall separated from the frame around the wheel arches. This is where the dust and sand entered the walls. To fix this problem I filled the opening with expanding foam. The foam seals and fills the small openings between the outside panel and the frame.

The next step in the building of our bus is to lay the electric cables for the 220-volt electricity and for the 12-volt lights. After the electricity is in, we can start with the insulation of the walls. We decided to use polystyrene in the walls and the roof for insulation, partly because it is cheaper but mainly because it does not get so could in South Africa as in Europe.
I have decided that the insulation of the bus will consist of the 40 mm polystyrene in the walls and on the inside of the walls, we will use 8 mm knoty pine. In the roof, we will use 40 mm polystyrene and 5 mm plywood with a wood veneer finish.
The floor is 25 mm marine plywood already fitted and covered with a 3 mm rubber lining on the inside. The final layer of insulation we will use is 10 mm hard wood tiles in the lounge and kitchen areas. The bathroom floor and walls and the shower cubical we will cover with ceramic tiles. The floor of the main bedroom and the passage that leads to the front of the bus we will cover in carpet. The carpet is for noise insulation as well. The inside walls of the bus can be build by using Meranti wood doors thy are strong and cheep.
