Stratco High Fronted Gutters Information Manual

High Fronted Gutters
High Fronted Gutters
High fronted gutters hide the lower edge of tiles or roof cladding which creates an aesthetically pleasing appearance. It is important
that sufficient overflow measures are included in the design of the guttering system and that high fronted gutters are installed in
such a way that if they overflow, it will not result in water flowing back into the roof or building.
The design of gutter and downpipe system installations also need to comply with specific rainfall intensities for the area of installation
and adequate overflow provisions need to be provided to prevent water from entering the dwelling during heavy rainfall periods.
Codes
The design and installation of guttering and downpipe systems
needs to comply with the Building Code of Australia and
Australian Standards AS/NZS 3500.3 Plumbing and Drainage,
Stormwater Drainage and AS/NZS 3500.5 National Plumbing
and Drainage, Domestic Installations. It is also important that
relevant State regulations are satisfied. For example, New South
Wales legislation requires all gutter and downpipe installations
be undertaken by a suitably licensed installer who holds a
current certificate issued by the NSW Office of Fair Trading.
Natural Effects
There are two natural effects in Stratco guttering that offer
some protection against water flowing from eaves gutters
inside a building, when attached to Stratco steel fascia.
• The first is that when installed on our steel fascia, the "high
front" of the gutter can still be lower than the top face of the
fascia. Water will always flow to the lowest point, and even
if a complete blockage exists, should still overflow outside
the eaves line (Figure 1 and 3).
INFORMATION
• Secondly, if a complete blockage occurs the additional
weight of the water will cause the gutter to temporarily
deform. The back of the gutter is restrained at 1.2 metre
intervals by fixing clips but between these points the gutter
moves outwards from the fascia creating a gap that allows
the additional water to escape (Figure 4).
