ONDUCLAIR PLR is a polyester roof light system reinforced with glass fibers, highly resistant to natural corrosion. It fits on agricultural buildings, industrial or residential ... roofing and siding. It is very easy to install.


ONDUCLAIR PLR is a polyester roof light system reinforced with fiber glass. The sheets have outstanding resistance to natural corrosion and are designed for translucent roofing and cladding (flat or curved) for any type of building, including the agricultural, industrial and residential sectors.... Easy to install, ONDUCLAIR PLR is an ultimate multi-purpose material.








Impact resistant


Fast to install

Light transmission








  • Improved well-being thanks to soft, diffused light and double-sided UV protection
  • Long lasting: resistance to hail and natural corrosion
  • Highly adaptable for more freedom in design


  • Save time during the installation: easy transportation thanks to lightweight sheets up to to 12 m long 
  • Benefit from fast and easy installation: only standard tools required
  • Adapt easily to any configuration: wide range of ribbed and corrugated profiles, translucent colors and thicknesses






Installation instructions 


1. The installation should be carried out with the ribs (or corrugations) running down the slope of the roof (longitudinal and transversal overlaps).

Horizontal laying: Opposite direction to the prevailing wind. Each sheet should cover the previous sheet along the adjacent longitudinal edge. 

Vertical laying: from the bottom up. The downslope lap (cut back) of the top sheet should cover the sheet below it. 





2. The fixings must include following accessories (waterproofing and loads distribution):

  • Sealing washers
  • Saddle supports or curved washers adapted to the profile and to the site corrosivity
  • Profile supports.

Because of the expansion coefficient of the material, fastener holes should be drilled to a diameter that is 4 mm larger than the fastener diameter. PVC washers should not be used. 





Typical profiles : 




GO 92











  • Crystal 
  • Opal
  • Translucent smoked brown: translucent yellow and translucent green
  • Opaque white
