Roofing Ventilation

Roll Out Rafter trays are a simple but effective way of preventing loft insulation from being pushed up to the underside of the roofing underlay and will maintain a clear ventilation path into the roof void from the eaves. The rafter trays will be suitable for 10,000 mm/m or 25,000 mm²/m continuous eaves ventilation.

• 300-600mm rafter centres
• New build and re-roofing applications
• 10,000mm²/m or 25,000mm²/m continuous eaves ventilation
• Suitable for roof pitches over 12.5^o
• Quick and easy to install
• Lightweight and durable

Suitable for:

• 300-600mm rafter centres
• New build and re-roofing applications
• 10,000 mm²/m or 25,000 mm²/m continuous eaves ventilation
• Roof pitches over 12.5^o

Available in four widths

Installation

The Roll Out Trays are rolled out over the rafters in the correct position to provide a clear ventilation channel above the roof insulation and fixed into the rafters using corrosion resistant clout head nails or staples. For low pitch pitched roofs two trays may be joined together and if using soffit ventilation the bottom edge of the tray must be kept minimum 25mm from the back of the fascia board.

The Roll-out Rafter Tray provides the equivalent of a 10mm or 25mm opening (10,000mm² and 25,000mm² per metre respectively). The rigid section Rafter Tray provides the equivalent of a continuous 10mm opening.
