Wall Expansion Joints are installed in buildings to allow for the movement and expansion of walls due to environmental factors and structural shifts. They are typically placed at regular intervals horizontally or vertically along the length of the wall. Wall expansion joints absorb the stresses and movements caused by temperature changes, moisture, and settling, preventing cracks and maintaining the stability of the structure. These joints also help to enhance the appearance of walls by providing clean and neat transitions between different sections or materials.
