Timber cladding problems usually start at the junctions — not in the middle of the boards.
Corners, windows, doors, base details and roof junctions are where water can enter, ventilation can be restricted and otherwise good cladding systems can begin to fail.
Our latest technical guide explains how these areas should be designed correctly.
It covers:
✔ External corner posts
✔ Window and door reveals
✔ Head flashings
✔ Base and DPC details
✔ Ventilated cavity construction
✔ Horizontal and vertical wall sections
✔ Cavity barrier detailing
✔ Common design mistakes
We have also made standard timber cladding detail drawings available to download free of charge.
For architects, developers and contractors requiring more detailed support, we can also produce project-specific PDF and DWG drawing packages.
The best time to resolve cladding details is before the material is ordered — not once the installation team is already on site.
