An interlocking, aluminium framed polycarbonate glazing panel system which is suitable for roof and wall installations, ranging from 10º pitch to vertical. The system is suitable for north-lights, patent glazing replacement, mono-pitch rooflights and vertical glazing. The versatility of the system means it can be used on ridges or abutting wall panels and gutters.

Features and benefits:

  • Suitable for both new build and refurbishment applications including factories, schools, leisure centres, logistics facilities and other open plan buildings.
  • Panels are sized and constructed specifically for each project, so there is no cutting or fabrication on site. The system can reduce site installation time by as much as 70%, due to its ease of fixing: only two screws are required for each panel (except the first panel, which requires four screws).
  • Lightweight.
  • Impact resistant and non-fragile.
  • Fully assembled and easy to handle.
  • Thermally efficient.
  • 20-year insurance protected guarantee provided - consult manufacturer for details.
