UV stable PVCu; guaranteed not to stain or corrode like galvanized steel beads

Performance

  • Complies with BS EN 13914-1&2:2005
  • BBA certified
  • Class 1Y fire rated
  • Flexible plastic membrane gives a certified range of +/- 2.5mm which exceeds British Standard for thermal movement (BS EN 13658-2:2005). Protective tear off strip allows quick removal of render from the joint
  • More cost effective than stainless steel
  • Not affected by weather - ideal for all habitable climates; eliminates cold bridging
  • Flexible plastic membrane provides a watertight seal. Not affected by weather and should be specified in all regions of high moisture or high salt
  • Reduced spalling and impact damage
  • Cleaned in same way as render
  • Designed to outlast its metal counterparts
  • Guaranteed to be fit for purpose for lifetime of the render and at least 25 years

Installation

Supplied in 2.5m lengths and in packs of 25.

Fixing with a continuous line of adhesive mortar is preferred on blockwork, or alternatively a bed of render.

Non-corrosive mechanical fixings can be used as well but are not required. With external wall insulation, non-corrosive fixings alone are sufficient

PVCu beading is fast and easy to cut to length with tin snips or a fine toothed hacksaw and is safer to handle than cut metal.
