- A simple yet splendid roofing system using natural materials and technology
as against the monotonous and complex conventional practices.
- Funicular shells can take any Shape- Square, rectangle, trapezium,
triangular or any other shape. The trick lies in casting the mould.
- The upper half of the edge beam is required to hold the stirrups only.
It is cast along with the funicular shell; therefore, it can be a triangular
- The funicular shell can carry various conduits, toilet pipes in the
area above the brick - bat layer. These can run along the periphery
where the maximum depth is available.
- Funicular shell roof facilitates in the installment of fixtures likes-
ceiling fans, light fixtures etc.
- Skylight can be introduced in the roof. This can be achieved by leaving
a hollow in the fibreglass mould while casting. Since the circle is
itself very strong when used in compression, so as a hollow also it
becomes very strong.
- The edge beam can be given a slight camber or lift in the centre,
about 1"-3". This way the beam also acts as an arch, comes under compression,
further increasing its load bearing capacity. This also reduces the
amount of steel and cement being consumed in the beam.
- The funicular shell allows ample flexibility in design. Since the
funicular shell acts as an arch, it takes load in compression and distributes
the load equally in all direction. Thus, on the first floor, the wall
can be placed anywhere since it will always rest on the arch.
