Once we finished the skeleton of the dome, we moved onto researching what materials would be appropriate as a cladding material. 


An example we would have liked to use as an exterior cladding, which is environmentally friendly, was prefabricated Alucobond Panels. This light weight material can be custom made to desired sizes. It is flexible, weather resistant, shock resistant and easy to install.


We did not use this product for this experiment as it was not readily accessible, and the cost was too expensive to get custom made for such a small scale project. 


Therefore we decided to use plywood, although not as water tight as Alucobond, we were able to access this product readily and it was cost efficient. 


It provide its purpose for this exercise as proved in the footage.


As we had to provide a window in the exercise, we decided to provide skylights instead. It was going to be very expensive for us to order glass, fibreglass or other products for our skylights. We were able to get a cheap off cut of perspex for our example of this in our geodesic dome exercise.
