Position the fascia board 20mm above the rafter to allow for the height of the Universal Eaves Filler Strip. Fascias should be of adequate density to secure a screw fixing.
Form a starter unit by cutting a standard Eaves Vent Tray in half centrally on the rafter (Picture 1).
Fix the starter unit to the gable rafter using a felt tack at the head of the tray (Picture 2). Ensure that the tray is positioned to allow water to discharge into the gutter.
Continue to fix additional Eaves Vent Trays along the eaves, ensuring that the chevrons are interlocked. At the opposite end of the roof, fix another half tray to the gable rafter as described in step 3 (Picture 3).
Once Eaves Vent Trays are in place, fix a Universal Eaves Filler Strip into the fascia board using screws. See Picture 5 for correct placement of Eaves Filler Strip. A minimum of 3 screws must beused to fix each unit (Picture 4).
For flat tiles, position the comb leaning up the roof slope. For profiled tiles, position the comb leaning away from the roof slope.
If extension trays are required (see next page), fix to the rafters using felt tacks. Ensure that Extension Tray chevrons are interlocked with the Eaves Trays beneath.
Roll out the underlay in the normal manner, ensuring that the edge of the underlay is level with the ventilation chevrons (Picture 6).

Depending on the depth of the insulation and roof pitch, it may be necessary to purchase extension trays to extend the ventilation path above the level of the insulation and allow free flow of air into the roof space. See diagram opposite. Extension packs are sold separately.
