Important Design and Installation
notes:
Over Fascia
Where
Over fascia Ventilator (C504/505) and Vented Eaves
Protector (C404) are specified the fascia height must be
reduced.
C404 -
reduce fascia height by 25mm
C504 -
reduce fascia height by 22mm
C505 -
reduce fascia height by 51mm
Installation
of an eaves protection unit will significantly increase the
life expectancy of the installation. The rear flange of the unit
must dress under the existing felt edge. (Fig1) Where
a capping fascia is employed ensure that any ventilation or
protection units are fixed into the top of the backing board
only. Where
eaves protection is not to be fitted the roof felt must be in good
condition and dressed over the fascia down into the gutter (Fig7).
In the case of severe deterioration, the roofing felt may require
complete replacement.Through Soffit
Ventilation may be provided via:
Pre-vented
boards ie Polo flat boards (Fig6) or cladding (Fig16).
See Soffits Installation Guide. A combination
of flat board (or cladding) and ventilation strips
(Figs19/21). A
circular ventilator is available where it is necessary to
provide ventilation through an existing flat board
soffit. |
