The criterion for allowed deflections is L/20.
For single span application use the end field column.
The mentioned load refers to both wind and snow loads and intended for rooflights only.

Positioning
Make sure the UV protected side faces out.
Lay the SUNTUF panel to overlap roof panels on both sides. If not feasible -
SUNTUF Rooflight panels must underlap the roof panels against the primary direction of rain.
The SUNTUF sheet must be located and installed without any stresses.
Do not pull, stretch or force the sheets when the profiles are not perfectly matched.
Fastening
Apply sealing tape over the SUNTUF panel side-lap corrugation crests, where covered by the next panel.
Apply sealing tape along the bottom and top End-lap (if there is), along screws centerline or two tapes
on both sides of screw centerline.
Pre-drill 10mm holes at crests where screws are positioned.
Start fastening the screws from the first side-lap (left) through the pre-drilled holes (3).
Start fastening the screws on the lower edge purlin (End-lap), through every other corrugation crest (1).
Fasten screws at the internal purlins, through every third corrugation crest, starting at the same side (2).
Fasten screws at the upper edge purlin, through every other corrugation crest,
starting at the same side (1)
Do not over-tighten!
• Fasten the stitching screws at every 300-400 mm (4).

Important Notes
Use only PALRAM approved accessories, including EPDM rubber washers, silicones,
sealing tape, closure fixtures etc.
For clear SUNTUF onto wooden purlins, apply white acrylic paint, or aluminum tape, in
order to prevent over-heating of the purlins.
Cutting Tips
Use jigsaw or circular saw with fine tooth blades.
Apply high blade speed with moderate feeding rate.
Support the sheets near the cutting line.
Clean the dust and cutting chips after cutting.
Fastening Tips
Use adjustable electric screwdriver.
The screw must be installed perpendicular to the SUNTUF sheet.
Important: Do not over-tighten.
Safety
Do not step directly on the panel.
Use stepping boards.
Work according to local safety regulations.
Handling and Storage
Store in a shaded place, protect from direct sunlight and rain.
Avoid covering the sheets with heat absorbing materials.
Avoid contact or environment of chemicals.
Protect the sheets from any physical damage.
