Semi-circular Barrel Vault Rooflights

 

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.

 

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.

 

The design may be glazed with 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.

 

All metal parts can be mill finish for economy or, alternatively, colour coated with polyester powder, PVF2 or anodised.

Shown here are photos from an installation, designed and constructed with semi-circular geometry.

 

Such details are indicative only— project specific designs and details are produced for each project engineered by Xtralite.
