Installation Guide · Exterior Siding
The Peruvian Teak All-Weather Composite Shiplap Siding installs with a concealed clip fastening system — no exposed screws on the face of the panels. This guide walks through every step, from substrate prep to corner trim finish.
The system uses two clip types: a starter clip that anchors the bottom row, and in-between clips that lock each subsequent row while allowing the controlled expansion and contraction the composite material needs. Done correctly, the result is a clean, professional wall with hidden fasteners and consistent spacing throughout.

Before anything else, identify the surface you're installing over. This determines whether you need furring strips before the siding can go on.
If the existing surface is solid, structurally sound wood sheathing:
You must install wood furring strips first:
Starter clips anchor the bottom row and set the alignment for the entire wall. Everything above them follows from this line — get it wrong here and the misalignment compounds with every row.
With your starter clips in place, install the entire first (bottom) row of shiplap panels before moving up. This row is the foundation — any out-of-level error here carries through every row above it.
Once the first row is in place, install the in-between clips along the top edge of those panels. These clips do two jobs: they lock the current row down and create the channel that captures the next row's bottom edge.
Repeat the process for every row: panels first, then clips, then screws. Work your way up the wall one full row at a time.
Complete the installation with matching composite corner trim at all inside and outside corners. Corner trim covers the exposed panel ends, creates a clean transition, and protects the edges from moisture infiltration.
Allow panels to acclimate at the job site for 24–48 hours before installation, especially if shipping from a different climate. WPC expands and contracts — let it reach local ambient conditions before you lock it in.
When screwing through composite material directly, pre-drill with a bit slightly larger than the screw shaft. This prevents cracking at the fastener hole and allows the thermal expansion the material needs.
Screws should be snug, not cranked down. Over-tightening compresses the clip channel and can warp the panel or prevent proper expansion — both problems that show up months after installation.
End joints between adjacent panels should not line up vertically between rows. Offset them by at least 24" for structural strength and a more natural, wood-like appearance on the finished wall.
A level check every 3–4 rows catches drift before it becomes visible. Small errors that are easy to correct at row 4 become a full tear-out problem at row 12.
Leave a small gap (1/4"–3/8") between panel ends and any fixed obstacle — window frames, door casings, trim boards. The in-between clip system controls vertical expansion; horizontal expansion at ends needs clear space to move.
When installed correctly, the concealed clip system produces a clean, unbroken wall surface with no visible fasteners. The Peruvian Teak finish holds color and texture through years of UV exposure, moisture cycling, and temperature swings — with zero maintenance required. No repainting, no resealing, no annual upkeep.
The shiplap profile creates horizontal shadow lines across the wall face that shift through the day as sunlight moves — the same visual effect as natural wood siding, without any of the upkeep.
