Product Information

The classic vault is a simple semi-circular rooflight that tops the supporting structure; alternatively it can be raised on vertical legs incorporating such features as windows, vents, or louvres. Ends can be terminated with vertical glazed screens or simply abut an adjoining structure.


  • Can be glazed in a range of polycarbonate options - from solid single skin for canopies and unheated spaces, to multi-wall structured giving exceptional thermal performance for Part ‘L’ compliance.
  • Finished in powder white as standard, other options available on request.
  • Metal parts can also be colour coated with polyester powders, PVF2 or anodised.

The spanning performance quoted assumes they are constructed with a classic semi-circular geometry and are self supporting; much larger spans can be achieved although a substructure for additional support would then be required.
