As we converted the Sprinter 4×4 in 2017 this wil be a commented photo report of the build

This is part one of the build where we will deal with the basic setup and insulation of the Sprinter. We made some unusual and maybe bold choices (using spray cork as well as Sheep wool for insulation)  according to the ‘specialists’. 

Sprinter for sale in Germany. It belonged to a German electricity company and was used for maintenance of wind turbines.
Installing the rear view camera and the brake light with ‘parking’ camera.
Installing the subwoofer under the chair
Painting the inside of the wheel arches and the steel frame, shocks and so on
Painting the rims with the new 265/75R16 Cooper ST/Maxx tyres
After the Sprinter was neatly back on its wheels, the Freerider was brought to Breda. The entire inside was insulated with spray cork by Petru from A to Z finishing. 3 layers of spray cork for heat, cold and sound insulation. But especially to exclude heat and cold bridges and to prevent condensation.
We think we are one of the first to have used spray cork as camper insulation. We did this in 2017 and after 5 years we can say that it works perfect, very good sound and heat - cold insulation and no condensation in the Freerider!
Installing side window
Looking much better with the bigger off-road tyres and the side window.
Second layer on the floor: 10 mm waterproof Oukome board
Amy finishing the second layer
Second layer of insulation walls: 5-10 cm thick Doscha Sheepwool (washed and treated so it will not smell).
Second layer of insulation roof: 5 cm X-trem with taped seams.
Third layer floor: 4 cm X-trem insulation
Oukome water resistant wood 0,5 cm on the roof
Fourth layer floor: 15 mm Oukome board with chair rails from a Renault Espace.
Electricity cables in the wall
We had to cut two holes in the roof. This one is for the Maxxfan in the front. We had to make a subframe on top to bridge the roof ribs.
All hollow spaces in the wall are covered with 5-10 cm Sheep wool. We have chosen the Sheepwool because it has very good 'moist-management' properties: it takes on moist when it is damp and lets it go when it is dry. creating a very comfortable atmosphere.
The hole in the back. We used a Gebo hatch from the boating industry. Much more durable than the 'plastic fantastic' camper hatches.
We used an old freeride ski to make a small cabinet at the entrance.
The back doors got the same treatment: spray cork, Sheep wool and Oukome wood.
Fully covered in Oukome, mega insulated Sprinter!
As we expected the Maxxfan would give a lot of noise (plastic fantastic) we decided to create a 'hood' made of wood + 5 cm insulation, it works!
The last layer on the floor: we used PVC because we wanted a 100% water- and skiboots-proof floor.
The floor is in, as well as the last layer on the walls and ceiling. We used cork (bark on ceiling) as it is a natural and breathing material, thus adding to the very natural atmosphere in the Sprinter. We drilled holes in the Oukome wood side panels so the Sheepwool can breathe as well.
