10/12: Expansion joints
» Go to tip 11: Garden walls or free-standing walls
Expansion joints are joints that absorb the expansion and contraction of the wall. There are 2 ways to make expansion joints.
- Straight expansion joint: this must have an opening of 5 mm or 10 mm with a backer rod and mastic seam.
- Staggered expansion joint: this must be open, with an integral guide that allows the walls to move independently of each other. The guide can be a foil or a thin foam slip of 7 to 8 cm wide and 3 mm thick. This expansion must be a building physical expansion on a longitudinal wall, so must not be made on the corners of a building.
