Advice: Corner details

Fixing Corners

There are number of different ways to detail the internal and external corners of a timber clad building. Here we offer illustrations of four common methods:

Solid block corner detail

Uses: Internal and external corners

This is the most commonly used and simplest corner detail. The block can be designed either to sit ‘proud’ of the cladding boards to create an over-hang or sit ‘shy’ to create a small recess. It is not advisable to line up the block with the cladding boards exactly because a small amount of movement will be noticeable.

The position of the block can be altered by moving one of the two battens located at the corner.

45 x 45mm block sections are available in a range of profiles.

Uses: Internal and external corners

This detail, which is often used for vertically orientated cladding, is created with simple square boards overlapping the corner. The cover board detail is reversed for internal corners.

Mitred corner detail

Uses: External corners

Done well, the mitred corner detail can look impressive, however a neat finish requires very accurate fixing of the boards and subsequent movement of the wood may spoil the appearance.

A mitred corner detail should only be attempted with air dried cladding boards

Uses: Internal and external corners

For a simple and cheap method of finishing the corner, this method is ideal. The corner block can often be cut from spare cladding boards and nailed with the same fixings.
