Wood Cladding: A Practical Guide for South African Homes
Wood cladding is one of the quickest ways to give a building character. A few rows of warm timber can turn a plain plastered wall into something that looks architect-designed. Little wonder it's showing up on everything from coastal holiday homes to suburban extensions.
Our climate, however, is tough on exterior finishes. Between strong UV, summer storms and salty sea air, natural wood cladding asks for a lot of care. This guide explains what cladding does, how timber copes outdoors and how to get the look with far less maintenance.
What cladding actually does for a building
Cladding is an outer skin fixed over a wall. Most people choose it for looks, but it does more than decorate. It also shields the structure behind it from direct weather, it can hide tired or uneven brickwork and, depending on the profile, it can add a layer of insulation.
That's why the choice of material matters so much. Indeed, cladding faces the full force of the elements every single day. So whatever you pick needs to stay stable, hold its colour and resist moisture for years, not just look good on handover day.
How wood cladding weathers in our climate
Natural timber is porous, so it absorbs and releases moisture as the weather changes. Over time, that constant movement can lead to cracking, cupping and gaps between boards. Meanwhile, UV light breaks down the surface and turns warm tones silver-grey.
To slow this down, timber needs a protective coating and regular maintenance coats. Woodoc's guide to sealing and maintaining exterior wood advises inspecting surfaces for cracks, peeling and wear, then applying a maintenance coat once weathering starts. On a double-storey facade, that often means scaffolding or a contractor every time.
In short, timber cladding usually comes with this to-do list:
Regular inspections for cracks, peeling and loose boards
Cleaning and light sanding before each recoat
Maintenance coats of sealer whenever the surface weathers
Spot repairs wherever moisture or insects get in
Choosing a profile: shiplap or tongue and groove
Composite cladding gives you the timber look without that maintenance cycle. At Acacia, our boards blend roughly 70% wood fibre with polymers and premium additives, so they resist rot, staining and insects. Equally important, they don't need sealing. From there, the main decision is which profile suits your project.
Shiplap for clean, overlapping lines
Our shiplap cladding uses an overlapping edge that creates a seamless finish and allows for natural expansion. Specifically, the boards measure 138 x 18 mm and come in 3 m or 6 m lengths. Also, they work inside and out, so you can carry the same finish from a patio wall into a living area.
ThermoCell for insulated facades
ThermoCell wall cladding is a grooved, tongue and groove board with hollow chambers inside. Those chambers then create a thermal air buffer, which helps with insulation and energy efficiency. As a result, it's a strong fit for exterior walls that take a lot of sun.
Getting the installation right
Good cladding depends on what's behind it as much as the boards themselves. Above all, a straight, stable sub-frame keeps lines crisp and lets air move behind the boards. For that reason, plan the substructure carefully before ordering anything, and check your quantities so you don't run short halfway through the job.
Measure each wall and subtract openings like windows and doors.
Allow about 8 m of shiplap, or about 6.5 m of ThermoCell, per square metre.
Plan a sub-frame, such as our composite battens, to fix the boards to.
Order the right fixings: about 30 clips and screws per square metre for shiplap.
Request samples so you can see the colour against your walls and roof.
Design ideas that work well
Wood cladding doesn't have to cover an entire house to make an impact. Often, a single feature wall does more than a full wrap. Here are a few ideas we see working well on South African homes, from modern builds to older houses getting a refresh.
Clad the entrance wall to create a welcoming first impression.
Run boards vertically on a double-storey section to add height.
Pair Charcoal cladding with white plaster for a crisp contrast.
Use warmer tones like Cinnamon or Camelthorn near gardens and pools.
Let's talk about your facade
Wood cladding brings warmth and character to any building, but natural timber demands a steady cycle of sealing and repairs. Composite gives you the same natural look, while letting you skip the scaffolding and the maintenance budget.
Acacia's shiplap and ThermoCell ranges are made in Namibia and designed for life outdoors. Contact our team to request product information, a quote or samples, and we'll help you choose the right profile for your project.
