Louvre Hopper
Water Diverting Hoppers
In extreme weather conditions and high winds leading to free
area velocities in excess of 4.5m/sec consideration should
be given to the attachment of a hopper to the rear of the
louvre.
Any water that does penetrate the louvre is collected by
the hopper and diverted back to the louvre drainage channel
then out through drainage holes in the louvre face.
Ventilation spaces that are specifically waterproofed or
tanked and louvres that have outward sloping ducts are not
as prone to water damage.
However, when fitting louvres in exposed positions such as
gable ends, multi-storeyed walls or buildings in exposed areas,
the effects of wind velocity and therefore water penetration
should be evaluated when choosing type and size of louvre
and the possible requirement of a hopper.
Material: 1.2 - 2mm Aluminium sheet, mill finish or powder
coated, sealed to rear of louvre.
