Design Factors
Building Regulations (Approved Document H) requirements.
The provisions to meet the requirements of the Building regulations
2000 (2002) are set out in Approved document H part H3.
An alternative to this requirement, is to follow the relevant
recommendations of BS EN12056-3:2000 Roof Drainage, Layout
and Calculation.
This document gives very comprehensive information on the
calculations/design of systems in a variety of situations, and
should be referred to whenever large industrial type installations
are envisaged or whenever particularly severe weather conditions
are expected.
Tests have shown that expansion and contraction of gutter occurs
during normal usage, and expansion tolerances are allowed for
within our fittings.
Carrying Capacities for Gutter
The carrying capacity of gutters varies under differing conditions.
The main variables are whether or not the gutter is fitted to a fall
and whether the outlet is placed in the centre or at one end of the
gutter run.
Gutter flow rates will vary according to the type and configuration of
downpipe system being used, however downpipe sizing is not a
normal design consideration, as the downpipe systems
manufactured by FloPlast have flow capacities approximately ten
times greater than the gutter systems they drain.
Expansion
Tests were conducted between -8oC and +40oC where an
expansion of 14.63mm was experienced over a 4 metre length.
These are obvious extremes, and under normal daily temperature
fluctuations expansion and contraction will be in the region of
10mm per 4 metre length.
