Roofline Slate Vent

Designed for easy fitting with all slate sizes, the 600mm x 300mm avoids the need for cutting upslope slates. All Corovent slate vents are supplied with a 110mm dia. Spigot for pipe termination as standard. This can be cut back to provide a full 10,000mm² ventilation.

Eaves Fascia Tray
The standard 1500mm FT150 trays are fixed above the fascia board form a lightweight rigid support for the lower edge of the underlay, which can be cut back short of the gutter.
 Formed from tough, rot-resistant rigid black thermoplastic. The FT150 is recommended for remedial and large roof areas for all slates and tiles.

Comb Filler
1000mm. No need to buy expensive, bespoke profiled fillers. Flexible, self-adjusting fingers fill gaps left when used with profiled tiles. Prevents entry of birds and large insects.
 

Continuous Rafter Tray (Rollout)
The Harcon continuous rafter tray has recently been redesigned in line with roofers’ requests. Typical roll formed rafter trays easily flatten and stretch, reducing the ventilation path. The Harcon 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.
 The width of the RT66 rafter tray has been increased to 400mm, significantly wider than most roll formed rafter trays, and the RT132 rafter tray has also been introduced with a width of 800mm. These rafter trays will cover 200mm of insulation at a minimum pitch of 300 (RT66) or 150 (RT132) and will provide increased tolerance of rafter tray positioning at steeper pitches or with thinner insulation: see diagram below. Note: As the thickness of insulation increases to comply with recent regulation changes particular attention should be paid to this area of the roof.
