Zenon for Site-Assembled Systems

Our site-assembled rooflights can combine Zenon Pro and Zenon Evolution weather sheet and liner panel configurations to suit the buildings requirements. Manufactured to match all commonly available metal cladding profiles for both new and refurbishment projects, the various sheet weights can be mixed and matched to meet the best performance criteria for the design of the building. Where insulated assemblies are required to meet Building Regulations and to improve building energy performance, our patented Insulator core or polycarbonate options can be selected.

All our insulated rooflight assemblies achieve U-values below the Building Regulations Part L notional building value of 1.8W/m²K. All our assembly combinations meet, or more often exceed, the required non-fragility classification as defined in RA Technical Document NTD03 in conjunction with ACR[M]001. Each sheet can be manufactured to the required fire grade. Uninsulated rooflight assemblies are available for agricultural building applications where Building Regulation requirements may not be applicable.


The options below demonstrate the effect that our different insulation choices have on building performance for the average Zenon Pro and Evolution assemblies. These are just some of the configurations available for site assembled rooflights, other options are available, please contact us to discuss specification requirements.
