| Pitch | 3–5°, with the length running along the slope in the surveying detail. |
| Upstand | Minimum 150mm high; 75–85mm wide in the surveying guide. |
| Manufacturer glazing range | Double- and triple-glazed options, with glass tints and laminated options subject to specification. Online choices may be more limited. |

Check area and dimensions separately
For a preliminary area check, multiply the two dimensions in metres. A 1.0 × 2.0m size is 2.0m²; a 1.5 × 2.5m size is 3.75m² and exceeds the stated limit. An area below 3m² does not by itself confirm that a particular width, length or glazing combination is available.
Use the correct installation document
Download the Flat Glass guide for this framed system. The FlatLite guide describes a different product and should not be substituted. Before ordering, agree the external measurement datum, glazing selection, fall direction and internal finishing detail with the installer.
