PVC BELLCAST BEAD

PVC Bellcast Bead for Render & EWI Systems

The PVC Bellcast Bead, also known as a drip bead, is designed to provide a clean, professional finish at the base of render systems while directing rainwater safely away from the wall surface. Manufactured from durable recycled UPVC, this lightweight render bead helps prevent water staining, damp issues, and premature render deterioration on external fa�ades.

Bellcast beads are typically installed above the damp proof course (DPC), around window heads, and at horizontal render terminations to create a controlled drip edge that prevents water tracking beneath the render system.

Suitable for use with silicone renders, monocouche renders, sand and cement systems, and external wall insulation (EWI), PVC bellcast beads help contractors achieve straight, durable, and weather-resistant render finishes.

Key Features & Benefits
- Creates a clean and professional render termination
- Angled drip profile helps deflect rainwater away from walls
- Reduces risk of water staining and damp penetration
- Durable recycled PVC construction
- Resistant to rust, corrosion, and weather exposure
- Lightweight and easy to install
- Suitable for modern render and EWI systems

Suitable Applications
PVC bellcast beads are commonly used for:
- External wall insulation systems (EWI)
- Silicone and acrylic render systems
- Monocouche rendering
- Sand and cement rendering
- Damp proof course (DPC) detailing
- Window and door heads
- Decorative fa�ade detailing and shadow lines

Why Use a Bellcast / Drip Bead?
Bellcast beads are essential in modern rendering systems because they create a drip detail that prevents water from running back underneath the render finish. This helps reduce moisture penetration, staining, and damp issues around vulnerable fa�ade areas.

Professional renderers frequently recommend installing bellcast beads above DPC level and around openings to improve water runoff and extend the lifespan of the render system.

Compared with traditional galvanised alternatives, PVC bellcast beads offer superior corrosion resistance and are less likely to cause staining or rust marks on coloured renders.
