Fabrication record
What aluminium roof lanterns can actually be built to
These are the limits the factory works to, taken from the fabrication data for the system we make this product in. Premium routes in the same family reach better thermal and acoustic figures than the ones below, and are quoted where the project calls for them. Either way this is the envelope, not a quotation: the achievable figures for your opening are confirmed against your drawings and a survey.

|---|---|
| Panels per run | 1 to 4 |
| Leaf width | 350 to 1200mm |
| Height | 400 to 2400mm |
| Maximum leaf weight | 120kg |
| Glazing unit | 24 to 44mm |

| U-value from, this system | 1.1 W/m²K |
| Security | Fixed structural-glazed rooflight (not a security-rated opening). |
