| Eaves
protection units are available in unvented and vented
formats. When vented versions are used the height of
the fascia should be reduced by 25mm.
Unvented
Jumbotec 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.
Vented Eaves Protector
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. |
