Rooflight Weight & Handling
Compared to old plastic rooflights, more modern glass rooflights are significantly more durable. But with that enhanced durability comes additional weight, which is important to consider at the early design and specification phase.
The weight of a rooflight is very important. If you are specifying a rooflight for an existing building, structural considerations and calculations must be made to ensure that the roof structure can take the added weight of a new rooflight. When designing and specifying for new builds, weight and load must be defined for the entire roof structure and considered at the early stages of the build.
Modern rooflight weights depend on their glazing type (e.g., double layer glazing vs. triple layer glazing). You will always be able to obtain the exact weight of your rooflight order, but if an overall initial weight estimation is needed, the graph on the left is a very handy tool.
