Introduction
When finishing facades and insulation systems, proper protection of building edges is essential. The most common solution is corner beads with mesh, which strengthen edges and ensure long-lasting plaster durability.
1. What are corner beads with mesh?
These are profiles (usually aluminium or PVC) factory-attached to strips of fiberglass mesh. They are installed in the adhesive and reinforcing layer of ETICS insulation systems.
2. Why are they important?
-
Reinforcement of edges – protect building corners against mechanical damage.
-
Crack prevention – the mesh distributes stresses in the plaster.
-
Aesthetic finish – provide perfectly straight and clean edges.
-
Durability – improve resistance of facades to weather conditions.
3. Where are they used?
-
On external building corners,
-
Around windows and doors (protecting reveals and edges),
-
In insulation systems with mineral wool or EPS,
-
Wherever corners are exposed to damage.
4. Installation steps
-
Apply a layer of adhesive along the corner.
-
Press the corner bead with mesh into the fresh adhesive.
-
Embed the mesh into the reinforcement layer, overlapping the facade mesh.
-
Smooth and level the surface, then allow to dry.
5. Common mistakes
-
Too little adhesive → bead detaches from the surface.
-
No mesh overlap → cracks and fissures appear.
-
Low-quality mesh → poor UV and moisture resistance.
Conclusion
Corner beads with mesh are a small investment that significantly increase the durability, strength, and appearance of facades. They protect corners, prevent cracks, and ensure the longevity of the entire insulation system.
