Note: These values are approximate and serve as a rough guide for
right-angled joints.

The depth of the joints is measured to the rear of the profile.
The authorised dimensions of the joints are governed by
DIN 18540. Accordingly all exterior expansion and
connection joints must have a minimum width of 10mm
and a maximum width of 35mm. Up to a width of 15mm
the depth of the joint should correspond to the width.
If the width of the joint exceeds 15mm, then the depth
should be approx 2/3 of its width.
