Expansion profiles (also called expansion joints or expansion profiles) are building components designed to absorb dimensional changes in materials due to thermal expansion, contraction, seismic activity, or structural movement. They prevent cracking or damage in floors, walls, ceilings, and facades by allowing controlled movement.
Application areas: Floors, walls, ceilings, facades, and bridges.
Types:
- Floor expansion profiles – allow movement in flooring systems.
- Wall/ceiling expansion profiles – cover and protect joints in walls and ceilings.
- Seismic expansion profiles – designed for larger movements in seismic zones.
