Continuous Roll Out Rafter Tray 400mm & 600mm
This continuous roll out rafter tray has recently been redesigned in line with roofers’ requests. Typical roll formed rafter trays easily flatten and stretch, reducing the ventilation path. This continuous rafter tray uniquely solves this problem by incorporating structural profiling which dramatically improves rigidity, so a full 25mm air path is guaranteed down the line of the roof.
As insulation becomes ever thicker, it is increasingly difficult to maintain a clear path to the eaves and locate the tray in the right place. Roof insulation can either slide below the tray and block ventilation, or push against the upper end causing blockage. Use of narrow rafter trays which do not prevent this should be avoided.
- Width 400mm & 600mm- Significantly wider than most roll formed rafter trays
- 6m length – fast to install
- Structurally profiled
- Better rigidty than standard continuous rafter trays
- Maintains a full 25mm air path down the line of the roof
- Will cover a 200mm depth of insulation at a minimum 30 degree pitch
