11.8 Flatsheet Rooflights 

Flat sheets of translucent material can also be used side by side to form a continuous roof light, wall lighting, or conservatory. Materials may be single or multi skinned glass, polycarbonate or acrylic.

These are almost exclusively proprietary systems so design advice should be sought from the distributor/manufacturer.
