This cladding fascia board installation guide explains how to achieve a durable and visually consistent finish on any cladding project.
What Are Fascia Boards in Cladding?
In a cladding system, the fascia board covers exposed horizontal edges, typically:
At the top of a wall, beneath the soffit or coping.
At the base of the façade.
Around balconies or parapets.
Purpose:
Provides a clean horizontal border between surfaces.
Conceals fixings and substructure components.
Complements corner and edge trims for a uniform design.
Fascia boards are made from the same composite material as the cladding system to ensure colour and texture consistency.
How to Install Composite Cladding Fascia Boards
Fascia Boards can be used to cover the cladding board edges and around window frames. This option can also be paired with corner trims around window frames and doors.
Additional battening is required around doors and windows, more battening may be required depending on your finishing option. It is suggested to use fascia boarding anywhere where horizontal cladding meets a roofline, window ledge or is going to butt up against a horizontal edge/barrier.
Step 1
Measure the amount of fascia boarding required and cut down to size.
Step 2
Place over the desired area. Make sure the edge of the fascia board sits flush with the cladded surface.
Step 3
Pre-drill and countersink the board.
Step 4
Screw into place with countersunk A2/A4 Stainless Steel screws.
Step 5
If desired, corner trim can then be placed over the fascia boards.
Common Mistakes to Avoid
Over-tightening fixings, leading to stress on the boards.
Skipping expansion gaps, which can cause buckling.
Poor alignment with main cladding boards.
Uneven mitre joints at corners.
Using incompatible fixings.
Avoiding these issues ensures your cladding edges remain crisp and visually cohesive.
