    It is a very complex and unique object, that could not be waterproofed without the use of future technologies (pure polyurea).
    The main purpose was to make the curved roof windows waterproofing.
    It was very complicated to make waterproofing on three different surfaces (glass, glassfibre composite and bitumen felt),
    it was a real challenge to connect three different materials together and do it successfully without later problems and remake of job.
