The Aero 90 product
has a unique anti-rattle profile and
was developed at the request of Australia's
largest construction companies, Baulderstone
Hornibrook, in order to overcome the
shortfalls of existing louvre shutters.
Before the introduction
of Aero 90, The University of Adelaide
conducted laboratory tests which sustained
that the Aero 90 shutter was suitable
 for the strong wind conditions
associated with high rise living.
For example, high-rise
balconies in exposed locations are constantly
subjected to high wind causing normal
shutters with inefficient wind seals
to howl and rattle.
 The tests
subjected the shutters to a wind tunnel
test and certified that the Rollashield
Aero 90 shutter was capable of with
standing  cyclonic winds to the
intensity of those experienced during
Cyclone Tracy, with each louvre blade
having an impressive 100kg breaking
strain capacity.
