Economy Slate Vent With Pipe Adapter
The COROVENT Economy Slate Vent is manufactured from long lasting injection moulded polypropylene that gives a matt slate grey finish. Use at low, mid or high level on pitches down to 200. The COROVENT HP1 pipe adaptor assembly should only be used with 600 x 300mm slates. HV1 / HP1 both provide 7, 200mm² ventilation area and include an integral 4mm insect screen. Can be cut to 500mm x 250mmwo versions give either 10mm or 25mm continuous ventilation, depending on  requirements of Building Regulations. They fit over the rafters above the wall plate and can be nailed or stapled to the rafters

HV1 600mm x 300mm

HP1 600mm x 300mm With pipe adaptor

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.
