Renderplas MJ20 is a 20mm PVCu movement joint manufactured from exterior-grade impact-resistant, UV-stable, unplasticised PVCu.

Designed for areas of render over 20m2, it should be specified every 4-6m, over structural movement joints and changes of background, giving a discreet, attractive finish.

Also for use as an internal corner with plasterboard.

Colour and appearance

Available in white only.

UV-stable PVCu; guaranteed not to stain or corrode like galvanised steel beads.

  • Class 1Y fire-rated

  • REACH-compliant

  • 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

  • Should be specified in all regions of high moisture or high salt

  • Dissipates shock waves

  • Reduced spalling and impact damage

  • Cleaned in same way as render

  • Designed to outlast its metal counterparts

  • Guaranteed to be fit-for-purpose for the lifetime of the render, and at least 25 years

Installation

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.

Supplied in 2.5m lengths and in packs of 25
