Sunpal Multiwall Polycarbonate panels use a standing seam and ‘T’ fastener system to give a very robust watertight finish. SUNPAL is available in a range of thicknesses.

The panels join together with with polycarbonate or aluminium joiners.  Aluminium joiner can be used to increase the spanning distances to suit your structure. T-Fasteners fix the entire system to the structure, allowing the panels to be clamped in place, without any point fastener penetration through the panels.  Aluminium End Caps or F-Sections can be used to seal the upper and lower ends of the panels. Aluminium F-Sections or Barge clips finish off side edges of the plane, creating a fully framed installation.
