Polyvinyl chloride (PVC) bellcast/ drip beads for external rendering and internal plastering, designed to provide a stop to the render just above the damp proof course and reveals.

Features and benefits:

  • Produces a straight edge.
  • Provides protection against impact and deflect rain water.
  • Can also be used as an architectural feature at each storey to provide a shadow.
  • Available in nine colours across all PVC bead profiles (except B10, which is supplied in white only).
  • Manufactured from recycled, exterior grade, impact resistant, UV stable PVC, providing a cost effective alternative to stainless steel beads.
  • Will not stain or corrode (like with galvanized steel beads), reducing spalling and impact damage.
  • Not affected by severe weather conditions, and can be specified in areas of high moisture or high salt.
  • Fast and easy to cut to length with tin snips or a fine toothed hacksaw, and is safer to handle than cut metal.
  • Fixing is no different from steel beads, and standard industry practice can be followed.
  • Supplied in 2.5 m lengths.
  • Durable; impact resistant and dissipates shock waves.
  • Can be cleaned or painted in the same way as render.
  • Has a high recycled content, and the product is fully recyclable.
  • Eliminates cold bridging, and is therefore suitable for all habitable climates.
  • Fit for purpose for the lifetime of the render; at least 25 years.

Performance/ Approvals:

  • Manufactured in accordance with the British and European standard for the design requirements of metal beads and lath (BS EN 13658-2: 2005).
  • BBA certified.
  • Class 1Y fire rated.
  • Manufactured in accordance with The British and European Standard for the design and application of external render (BS EN 13914-1: 2016), which stipulates that only PVC beads and stainless steel beads can be used in all applications including situations of high atmospheric or background moisture and high atmospheric or background salt.

Applications:

Suitable for all standard rendering applications, external wall insulation, timber frame and other weather board systems to provide a drip for rain water at the damp proof course, and above windows and doors to prevent return of the water onto the surface below. The product is safe to handle and is therefore also suitable for use in prisons and schools.

Store vertically away from heat and direct sun, or flat if supported along the entire length.
