How to Install Aluminium Fascia and Soffit

Much like other materials of roofline, Aluminium Fascia and Soffits are incredibly easy to install! Their lightweight nature makes them a great choice for a quick and easy upgrade to any property.

Follow the steps below for a smart and seamless installation:

  1. Ensure all of your materials are sound and suitable for fixing to.
  2. In most circumstances, start with the soffit sections first and ensure that any closer trims or battens are securely fixed or recesses are cut horizontally in line with the build.
  3. Starting from a suitable position (normally a corner), securely hold the part in place to the wall and safely secure (if to a trim or recess) or fix using stainless steel fixings according to the material being fixed to. Apply a 6mm bead of the recommended silicone sealant Arboseal 1096 approximately 20mm from one end and all-round the side of a union and place under the fixed part.
  4. Apply another 6mm bead of silicone sealant to the other end of the fixed part and place the next part over this, allowing a 2-3mm gap for thermal expansion.
  5. Continue to fit the remaining parts, supporting them at the timber/metal fascia edge.
  6. For the fascia, work to the same pattern as the soffit and securely fix in place all panels with stainless steel fixings at a spacing of 300mm. There should be no fixings made to the unions as they need to be free when allowing for thermal movement. It is further recommended that a 7mm hole is drilled when using 5mm fixings, as that also allows for thermal movement.
  7. For a complete finish, ensure that all cut edges and visible fixings are covered with the supplied touch-up paint and that silicone sealant is applied to the expansion gap and then smoothly tooled off.
