Unvented over fascia protection is a rigid PVC extrusion. It is fixed to the top of the fascia and supports roofing felt immediately behind the fascia. Unsupported felt often collects water, a process known as ponding. It then deteriorates and allows moisture through to the rafters.

The Vented Eaves Protector (C404) provides over fascia protection in a similar way to Jumbotec above. In addition it provides over fascia ventilation equivalent to a continuous 10mm air gap.

A separate Bird Comb (C405) may be attached to keep out birds and large insects in conjunction with profiled tiles.
