Where larger rooflights are required, over and above single maximum pane sizes, we can supply multi-section rooflights. These provide the same characteristics and sleek profile as the single pane units. These rooflights are often specified to bring natural light to internal corridors.

Maximum spans up to 3.2 m can be accommodated (free span slope length 3.2 m). There is no limit on the length of the rooflight. Bay centres depend on span width.
