ASSOCIATIONS
Five properties influence performance of an entire cladding system.
sheets and ancillary items together with
side and end laps determine the
waterproofing capabilities. The type of
fastener used to attach ancillary items to
the profiled cladding has a major influence
on both the waterproofing and structural
performance of a system.
Installation
Is the cladding system going to be installed
by an approved and competent installer
whose workmen have been trained by the
manufacturer? This is important as many
installers use transient and / or sub-
contracted labour. Failure to comply with
this requirement can have a negative
impact on warranties.
Durability
Durability is dependent on thickness and
type of coating. Not all coatings perform
equally in all environments. In our opinion
it is bes t to insist on compliance, preferably
with SANS standards, failing which other
internationally recognised standards for
both the manufacture and performance
testing of the materials. It is of the utmost
importance that the durability of the
protective coatings on exposed fasteners is
equal or better than that on the cladding.
As almost all roofing fasteners are imported
it is important to establish that the
protective coatings comply with SANS 1273.
Maintenance
Maintenance requirements for a system can
have a considerable influence on the life
cycle costs of a cladding system and need
to be considered. Insisting on compliance
with SANS standards, which are written for
local conditions, will greatly reduce the
risks when assessing alternatives.
