Easy Installation
SUNTUF should be installed with its sticker 'This Side
Up' facing the sunlight. This is the side that has been
treated with a protective coating against UV rays and
therefore protects the sheet's durability. The sticker
should be removed immediately after installation. When
cutting SUNTUF you can use a wide range of cutting
tools. However, for simplicity we suggest tin snips, a
fine tooth saw or a fine tooth circular saw. When moving
about or working on top of SUNTUF always walk on
crawling boards placed above the purlins.

Roof Pitch
SUNTUF Polycarbonate Sheeting will provide correct
run off of rainwater when the roof pitch is 5° [87mm
per 1000mm] or greater. If a flatter pitch is required
then additional weatherproofing should be attained
(consult your local distributor for fixing advice).

Overhang
To avoid sheet damage in high wind areas the
maximum hangover at the roof edge or gutter line
should not exceed 50mm.

Purlin & Batten Spacing
SUNTUF Polycarbonate Sheeting should normally be
fixed to purlins or battens at the below spacings. In
areas exposed to high wind, spacings should be
reduced to 750mm maximum end spans or consult
your local distributor for fixing advice.

Infills
Foam infills are recommended and available for all
profiles and flashing situations for weather and vermin
proofing.

Fastener Locations
SUNTUF is firmly fixed when fastened at every third
corrugation and every second corrugation at gutters,
ridging and overlaps (consult your local distributor for
fixing advice). When using SUNTUF in a roofing
situation, fastening is best through the crest of the
wave and for fences or walls, fastenings should be
through the valleys.

Fixing Screws
SUNTUF recommends the use of ‘Clearfix’ fasteners
when installing polycarbonate sheeting, alternatively
standard fixing screws must be compatible with
polycarbonate sheeting. Approximately 8 per sqm
are required. Overtightening of screws should be
avoided to prevent stress and damage to polycarbonate
sheeting. SUNTUF should be fixed firmly but in such a
manner that contraction and expansion can occur.

Special Points
Fixing: Fix sheets with UV protection facing the sun -
as indicated on sheet stickers. Only SUNTUF screws
and fasteners should be used to maintain warranty
requirements. Silicones and other chemicals not
compatible with polycarbonate must be avoided.

Expansion Allowance
At least 10mm clearance should be left when butting
to wall or fascia. Ensure a 10mm clearance hole is predrilled to allow for expansion and contraction.

Overlapping Sheets
Length overlap should be 200mm. Side overlaps should be as per diagrams below.

Height - Special Note
SUNTUF complies with AUSTRALIAN STANDARD
1562.3 - 1996, thus eliminating the new requirement
for safety mesh under roofs over 3 metres above
ground level. Consult your local SUNTUF Distributor
for fixing advice, if any portion of your roof is higher
than 3 metres. Approval may be needed in
accordance with the regulations of your local council.

Handling and Storage
SUNTUF sheets should be handled with care to avoid
any unnecessary scratches prior to installation. SUNTUF
should be stored on a flat surface away from direct
sunlight. When stacked together this will prevent
possible magnification of the sun’s rays through the top
sheets which may cause distortion of the lower sheets.

Cleaning
SUNTUF will continue to look new when it is washed
down regularly with a soft sponge and warm soapy water.

Care
SUNTUF Polycarbonate Sheeting is unaffected by a
wide range of chemical substances however, it is
important to avoid chemicals, paint, adhesives or other
synthetic materials that are not compatible.

Fire Rating
SUNTUF Polycarbonate Sheeting has a low
flammability rating and does not release strong toxic
gases when burning. SUNTUF Polycarbonate Sheeting
has been tested with a procedure conforming to
AS1530, 3-1982 (Australian Standard Methods for Fire
Tests on Building Materials and Structures, Part 3 -
Tests for Early Fire Hazards Properties of Materials).

Caution: Patio Heaters
It is recommended that patio heaters are situated no closer than 1 metre away from SUNTUF Polycarbonate Sheets. It is also important to ensure that adequate ventilation is provided at all times. If the temperature underneath your sheets rises above 90 degrees Celsius, immediately remove the patio heater from underneath the polycarbonate sheeting.
