How this node works
At the ridge the two air gaps meet and vent upward through a ventilated ridge; a sealing band under the ridge tile lets the air out while keeping rain and snow off.
Key points
- Ventilation cavity (outlet)
- Ridge vent (air outlet)
- Ridge tile + fixing
- Under-ridge sealing band
- Insulation continuous at the ridge
