To combat the condensation usually associated with a singleskin ceiling a series of vents is arranged along each side at the top of the,coving panels where they join the plastics panel.
The roof is virtually in one piece and the translucent panel is fixed along both longitudinal edges, with a limited number of screws across the roof. These screws have leather and metal washers to picvent vibration.

The plastics panel is smooth on both sides to avoid the possibility a soot and dirt lodging in its surfaces.
