Point Load on Translucent Sheets

Standard profiled roof lights are classified as brittle roofing and are not suitable for roof traffic. They are normally laid over safety mesh to AS 4859.  (See Safety Netting)

Trafficable roof lights are normally rendered trafficable by embedding a woven glass mat into the material. They must be tested under the point load test provisions of AS 4040.1, AS/NZS 4040.4, and AS/NZS 1562.3: 2006. Plastic roof lights.

Non-trafficable sheets over one sheet in width should be provided with a walkway, terminate short of ridge and/or eaves, to enable transverse traffic.
