Fascia Selection (9mm or 16mm)
9mm Fascia Board
9mm board should only be used for refurbishment and renovation
when fixed on to existing sound timber. The 9mm board should
not be fixed directly to a gable ladder. If existing timber
is damp, rotten or if its condition is in any doubt, use
the 16mm replacement fascia board range.
16mm Fascia Board
16mm board can be fixed directly onto gable ladder. The
16mm board is generally used in new built and 'rip-out'
situations. It is generally regarded as a premium solution
due to the boards superior strength and rigidity.
Fixing
-
Cut (or pack) rafter feet to a neat line.
-
Allow wood preserves to dry before fixing
fascia.
-
Fix into sound substrate only.
-
Sarking felt should be replaced if damaged
back to the first batten or a minimum of 300mm (use P89).
-
Roof tiles must not be solely supported
by fascia.

-
Gutter brackets must not be solely supported
by fascia.
-
For deeplas 9mm boards, localised support
behind each gutter bracket is required.
-
For deeplas 16mm boards every third fixing
must be into structural timber (as a minimum).
-
Use stainless steel fixing screws (minimum
9mm or 16mm - dependent on fascia choice) longer than
recommended by the gutter manufacturer.
Jointing
-
Allow 10mm expansion between joints (16mm
for forward fascia) and 5mm at each end (8mm for foiled
fascia).
-
Nail corner trims to rafters.
-
For butt joints, fix appropriate trim
to one fascia end and allow a 5mm expansion gap to the
butting board. (8mm for foiled fascia).
-
Cover exposed ends with appropriate end
caps - use solvent based adhesive.
Gable Box Ends
Box ends can be formed in a number of ways as single or
jointed assemblies as dictated by site parameters.
-
Cut fascia, soffit and corner moulding
to length.
-
Position and secure as normal.
-
From a wide board cut a box end to shape
and size. Cut joints vertically where possible to minimise
the risk of moisture ingress. Horizontal joints must be
completely sealed.
-
Locate box end into corner moulding and
fix into soffit/rafter using plastic headed nails.
-
Measure and cut box end return fromfascia
board.
-
Fix using plastic headed screws (fabricate
fixing framework if required).
