Mesh-wing render beads
Technical product reference for mesh-wing render beads used for corner and edge reinforcement on Australian facade remediation projects. Covers alkali-resistant fibreglass mesh integration, aluminium and PVC profiles, AR mesh specification, and application in re-rendering and EIFS systems.
What are mesh-wing render beads?
Mesh-wing render beads are arris angle beads and stop beads with factory-attached alkali-resistant fibreglass mesh wings integrated into the bead flanges. The mesh wings extend from the bead body and are embedded in the render base coat during application, providing reinforcement at render corners and edges.

Rondo Mesh-Wing Corner / Stop Bead
Mesh-wing render bead — corner and edge reinforcement
System Description
Rondo mesh-wing render beads are angle beads and stop beads with factory-attached alkali-resistant fibreglass mesh wings on each flange. The mesh wings are embedded in the render base coat at the time of application to provide reinforcement at render corners and edges — reducing stress cracking and improving impact resistance at these vulnerable locations. The mesh wing extends from the bead body approximately 50–100mm onto the render surface on each side. Confirm mesh wing width, bead profile, and available materials with Rondo. TODO: owner confirm — Rondo mesh-wing bead specification, mesh width and available profiles.
Technical Properties
- Integral alkali-resistant fibreglass mesh wings — embedded in render base coat
- Mesh wing extends approximately 50–100mm on each side of bead — confirm from Rondo
- Available as corner bead and stop bead profiles
Limitations
- Mesh wings must be fully embedded in render base coat — mesh must not be visible in finished render
- TODO: owner confirm — Rondo mesh-wing bead specification, mesh width and profiles
- Mesh wing requires sufficient render thickness over it — confirm minimum DFT for mesh coverage
PROCUREMENT SOURCES
Confirm suitability with the current manufacturer TDS before specifying or applying.
USG Boral Mesh-Wing Corner / Edge Bead
Mesh-wing render bead — corner and edge reinforcement
System Description
USG Boral / Beadex supplies mesh-wing render beads with integral fibreglass mesh wings for corner and edge reinforcement. Confirm bead profile, mesh wing width, and available materials with USG Boral. TODO: owner confirm — USG Boral mesh-wing bead specification and dimensions.
Technical Properties
- Integral fibreglass mesh wings
- Corner and stop bead profiles
- Exterior render reinforcement
Limitations
- TODO: owner confirm — USG Boral mesh-wing bead specification
- Mesh must be fully embedded in render
PROCUREMENT SOURCES
Confirm suitability with the current manufacturer TDS before specifying or applying.
Trade-Supply Mesh-Wing Render Bead (PVC / Aluminium)
Trade-supply mesh-wing render bead
System Description
Mesh-wing render beads are available through specialist render suppliers and plasterboard merchants. Confirm that the fibreglass mesh is alkali-resistant (AR) grade before purchasing for use in cementitious render systems — standard glass fibre mesh is not suitable in alkaline cementitious environments.
Technical Properties
- Trade supply — render specialists and merchants
- PVC or aluminium bead body
- Integral fibreglass mesh wings
Limitations
- Confirm AR mesh grade — not all trade-supply mesh-wing beads use alkali-resistant mesh
- Mesh must be fully embedded in render base coat
- Confirm mesh wing width for render panel coverage
PROCUREMENT SOURCES
Confirm suitability with the current manufacturer TDS before specifying or applying.
System Comparison
Side-by-side comparison of mesh-wing render bead products. Confirm all product selections against the current manufacturer TDS before specifying.
| Product | Brand | Bead material | Mesh type | Mesh wing width | AR grade | Suitable application | Primary use |
|---|---|---|---|---|---|---|---|
| Rondo Mesh-Wing Bead | Rondo | Aluminium or PVC | Fibreglass mesh | 50–100mm each side — confirm from Rondo | Confirm AR grade from Rondo | Exterior and interior — masonry, AAC, concrete | Corner and edge reinforcement — render systems |
| USG Boral Mesh-Wing Bead | USG Boral / Beadex | Aluminium or PVC | Fibreglass mesh | Confirm from USG Boral | Confirm AR grade from USG Boral | Exterior masonry render | Corner and edge reinforcement |
| Trade-Supply Mesh-Wing Bead | Trade Supply | PVC or aluminium | Fibreglass mesh — confirm AR grade | Confirm from supplier | Confirm AR grade — not all trade supply | Exterior masonry, AAC — confirm application | Corner reinforcement — trade supply |
Do not confuse mesh-wing render beads with:
- Standard arris corner beads — perforated flange only, no integral mesh wing — do not provide the same level of tensile reinforcement at corners
- Fibreglass reinforcing mesh (roll mesh) — applied separately as a continuous sheet over the render base coat — not integral to the bead profile
- EIFS mesh — fibreglass mesh embedded in render over EPS insulation board — different application and specification from mesh-wing bead reinforcement
