SUNTUF sheets must be transported and stored horizontally on a flat, sturdy pallet whose dimensions are equal to or larger than the sheets

The sheets must be fastened and secured to the pallet

It is possible to store sheets of smaller dimensions on top of sheets that are larger. (Never store sheets of larger dimensions on top of smaller sheets.)

The pallet must be stored in a cool and shaded location.

Never cover or place materials that are good conductors of heat on the pallet

In cases where it is necessary to store the pallet outdoors, it is possible to cover it with any material that does not absorb or conduct heat.

Scissors, shears or circular saws (with a fine tooth blade) will all cut sheets easily

Ensure fall or pitch is a minimum of 5 degrees (87mm per 1000mm) to prevent water flow back and dirt build-up

Radius curving for IBR is not recommended. The required minimum radius for Corrugated is 6m, while the Omega profile requires only 3m radius

Drilling should be carried out with a drill bit intended for metal.

The whole diameter must be 2mm greater than the diameter of the screw.

It is important to support the sheet before drilling.

The swarf generated by the drilling must be cleared away before inserting the screw.

To allow for sheet expansion, screw holes should be pre-drilled with an 8mm drill bit.

At least 10mm clearance should be left when butting to wall or fascia.

Foam closures are recommended for weather and vermin proofing.

Silicone - it is recommended to use either Dow Corning 3793 (white), Dow Corning 916 (clear) or Dow Corning 917 (grey)

Chemicals not compatible with polycarbonate must be avoided

The measurements shown (see Table above), are recommended maximums but can be reduced to suit your application

Space Tape is recommended to reduce noise associated with expansion and contraction

Fix the sheets with UV protection facing the sun as indicated on sheet stickers

The sheets should be laid down on the roof against the primary direction of the rain.

Never leave panels untended until all the required screws have been tightened

Length overlap should be 200mm

Side overlaps should be as per profile dimensions

To avoid sheet damage in high wind areas the maximum overhang at the roof edge or gutter line should not exceed 150mm

Allow a minimum of 50mm overhang into gutters

75mm fasteners and washers should be used when fixing IBR or Trimdek profiles to wooden purlins or battens. 65mm Self Drilling screws and washers should be used when fixing to steel purlins

25mm fasteners and washers should be used when fixing Corrugated or Omega profiles to wooden purlins or battens. 25mm Self Drilling screws and washers should be used when fixing to steel purlins

Each fastener should be fitted with a concave corrosion resistant metal washer that is at least 1mm thick and 25mm in diameter

Bound to the underside of this washer must be a rubberised disk of at least 2mm thickness made from either neoprene or EPDM

Panel to panel fasteners are used to create a seal between overlapping panels

Where the pitch of the roof is lower than 15%, one should place these every 600mm

For pitches greater than 15%, they can be placed every 500mm

A hole, 10mm in diameter, must be drilled before insertion

It is recommended that every crest be fixed

Inner purlins - A screw should be fastened at each third corrugation crest.

End purlins - A screw should be fastened at each second corrugation crest.

Inner purlins - A screw should be fastened at each third valley.

End purlins - A screw should be fastened at each second valley.

Overlap - A screw should be fastened on the crest at the overlap.

It is recommended that a variable speed electrical screwdriver with clutch be used

All screws must be inserted perpendicular to the purlin

Calculate approximately 8 fasteners per square metre

Over-tightening of screws should be avoided to prevent stress and damage

It is recommended that stitching intervals of 600mm be maintained

A fastening screw must be inserted along each major corrugation at each purlin position

The screw should be inserted through the upper panel over each purlin

The screw should be tightened without deforming the rubberised washer or distorting the corrugation
