Venlo glass vs multi-span film
Same gutter-connected logic, different envelope economics.
| Venlo glass | Multi-span film | |
|---|---|---|
| Span and bay | 9.6 / 10.8 / 12 m spans, 4.0 / 4.8 m bays | 8 / 9.6 / 12 m spans, wider bays |
| Gutter height | 4.0–7.0 m | 3.0–5.0 m |
| Vent area | A vent on almost every ridge | Roof vents per bay, side curtains |
| Equipment fit | Screens, heating, CO₂, lights all standard | Screens and heating possible, tighter space |
| Snow performance | Designed per site, sheds snow off narrow roofs | Needs careful design; wide bays hold more snow |
If you plan to add climate systems within five years, the film house starts to close the gap; if you are building for twenty years of high-value production, glass is the base case.
