Universal/Ogee Board and
Multi-Purpose Soffit
The Fascia should have a suitable existing or new backboard.
The universal/ogee board should be fixed so that the weight of the eaves course of tiles is distributed across the backboard and/or tilt fillets.
The soffit board should be supported on bearers at the foot of every rafter and be securely supported at each end. A preferred method is to support them by battens nailed or screwed to the rafters as shown in the diagrams.

New Build Replacement
Mammoth Board and Vented Soffit
When Mammoth Fascia is specified the roof covering should be supported by adequate means at the rafter ends. This can be by means of a tilt fillet, lay board or a shaped batten which extends the full length of the roof line. A lay board is particularly desirable in the case of pitches less than 30° as it will prevent any sagging of the Sarking felt.
Vented soffit boards are available in a range of sizes when roof ventilation via the soffit is specified.

Mammoth Board and Multi-Purpose Soffit

It is not always necessary for the soffit to fit into the groove at the back of the Mammoth board. Diagram (c) shows a deeper Mammoth fascia, which has been chosen for design or appearance criteria, the Multi-Purpose soffit butts against the back of the Mammoth board and is fixed to each soffit bearer with two 40mm FloTop Pins.

Mammoth Ogee Board and Vented Soffit

The diagram shows the Ogee style Mammoth fascia; the appearance of this board makes it particularly favourable for the specifier and homeowner alike when trying to achieve a period appearance. When used in conjunction with Decorative Bargeboard Mouldings and Niagara® Gutter, an otherwise mundane appearance can be transformed into an aesthetically pleasing feature to a property.
