  • Marlon CS Ztop is a high quality, extruded, corrugated polycarbonate sheet with a co-extruded UV resistant coating
  • As polycarbonate is a thermoplastic, it is important to take thermal expansion and contraction into account during any installation process.
  • Marlon CS Ztop has been independently tested to various Fire Standards; for the most current certification please contact our Technical Department.
  • Marlon CS Ztop is REACH and RoSH compliant, and 100% recyclable
  • Any colour option is a through-colour so the colour of a cut edge will match the colour of the surface.
  • Marlon CS Ztop sheets are covered by a limited warranty.  For full details contact our Technical Department

Storage & sheet preparation 

  • Store sheets on a flat surface. Use an opaque cover, tightly secured, to protect from wind, rain and sun.  Storage is always preferable indoors.
  • Ensure that the smooth surface of the Marlon CS Ztop sheet is to the outside.
  • Marlon CS Ztop sheets are installed with the corrugation running horizontally.
  • Roofs glazed with Marlon CS Ztop should always be designed with a minimum slope of 15° to allow adequate rainwater run-off.
  • Marlon CS Ztop sheet can be cut with a fine tooth circular saw or hand saw at a shallow angle.
 
Installation & fixing 

 

Important - polycarbonate sheet will expand in the heat and contract in the cold.

  • Start at the top of the structure, this eliminates the need to stand on the sheet during installation.
  • Applying foam tape to the top of the rafters can reduce noise and ease thermal expansion.
  • Lay the sheet with the corrugations running horizontally across the structure.
  • Fix with EPDM backed washers on fixings at 225mm centres on all rafters. 
  • Fixing holes should be oversized to allow for thermal movement of the sheet. A 10mm fixing hole should be adequate for 4.2mm fixings.
  • Fixings must not be overtightened, again this allows the natural movement of the sheet and will avoid unnecessary damage to the sheet.
  • Marlon CS Ztop sheet must be isolated from plastisol and flexible PVC paints and coatings using an aluminium barrier tape.

Finishing

Ensure that all sealants and tapes are compatible with Polycarbonate.

  • All accessory products should be light coloured, preferably white.
  • Sheets which span up to two purlin spacings are of optimum length to cope with thermal movement.
  • Maximum recommended sheet length for Marlon CS Ztop is 4.5m.

When installing any roofing material, including rooflights, ensure that safe working methods are adopted and appropriate safety equipment is used.

As a condition of ensuring that Marlon CS Ztop sheets perform at optimum throughout their service life and retain light transmission properties, it is recommended that the sheets be cleaned periodically using suitable household cleaning agents as follows:

  • Use lukewarm water to rinse the sheet and soften dirt.
  • Make up a solution of lukewarm water and ordinary household cleaner or a mild soap and use this to wash the sheet.
  • A sponge or soft cloth should then be used to gently remove dirt and grime.
  • The cleaning process should then be repeated and the sheet rinsed and dried with a soft cloth.

WARNING

Care should be taken to observe the following precautions:

  1. Do not scrub Marlon CS Ztop sheet with brushes or sharp instruments as the sheet will mark easily.
  2. Never steam clean, use low pressures for pressure washing.
  3. Avoid any abrasives or cleaners of a highly alkaline composition.
  4. It is generally advisable in all instances to test any cleaner on a sample piece of the Marlon CS Ztop sheet first and it should also be remembered that cleaners and solvents which state that they are suitable for cleaning polycarbonate may not be safe for use on the UV protective surface of the panels.
