Installation Guide – Siding Aluminum

• 

  - 1 -

  Important notes

  • Use galvanized screws #8 x 1.5’’ every 16’’
  • Aluminum undergoes expansion and contraction due to temperature variation. Do not screw completely. Keep 1/16’’ and screw in the center of the slot.
  • Always use a piece of wood to “snap” the cap on the base of the accessories. A protection must be used on the aluminum not to damage the texture.
  • When installing the siding on steel bars (Z-Bar), there must be a membrane on the nailing surface so that the aluminum is not in contact with the steel.

  To Start

  • Install the base of the J-Trim, H-Trim and outside corner first.
  • Screw through the base every 16’’, leaving a 1/16’’ gap between the screws and the aluminum to allow contraction/expansion.

  Starter Strip

  • Install the starter strip as showed and keep 3/16’’ on both ends for expansion and contraction.
  • Make sure the starter strip is leveled.

  • Install a small spacer 0.400’’ to avoid movement on the last row.

  Adjacent Planks

  Soffit

  • The plank can be used as a soffit. The junction from the wall to the soffit is done as an inside corner. (Step 8.)
