MODERN, CRISP
DETAILS THAT LAST
THANKS TO RENDERPLAS
MOVEMENT JOINT BEADS
Renderplas PVC movement joint beads were critical components in
the successful rendering of Treliske Retail Park in Truro, Cornwall.
Bruce Clarke of Somerset Plastering, who undertook the 1,300m 2
render refurbishment, says; “The use of movement joint beads
should be considered on all rendering projects. All buildings move
over time and the rendered surface of a facade is no different.
Whether the sun is shining on an aspect or freezing rain is lashing
against it, render will be continually expanding and contracting.”
Often overlooked, the specification and installation of movement
joint beads is essential if a rendered surface is to survive and
maintain its clean, crack-free look. When the temperature of the
rendered surface increases or decreases, the movement joint
beads allow room for the render to expand and contract without
cracking. Renderplas movement joint beads are guaranteed for a
minimum of 25 years or for the life of the render, so their use can
significantly reduce the need for expensive maintenance.
Renderplas, who make the only BBA-certified PVC movement joint
beads, recommend that they be used on any rendered surface
over 20m 2 . They should be specified every 4-6m, over structural
movement joints and over all changes of background.
The presence of the expansion joints can also become a design
point by creating definition lines that enhance the aesthetic of the
Renderplas continues to lead the market with innovations and
developments and offers a comprehensive choice of 9 colours
across the only BBA certified range of profiles including
movement joint beads.
Somerset Plastering, whose mantra is “It’s all in the detail”,
have been using Renderplas PVC beads for nine years. Bruce
says, “We’ve found again and again the beads’ ease of use is
unbeatable.”
Used at internal corners and where two colours meet, Renderplas
movement joint beads will ensure that the rendered facade of
the Treliske Retail Park will remain maintenance free and looking
good for many years to come.
Daniel Leedham-Green, Managing Director of Renderplas,
commented on the application “I am delighted by how well this
use of movement joint beads has worked. As well as defining the
two render colours they also bring such a modern and crisp look
to a functional building. To see them working so beautifully is
very impressive.”
All Renderplas beads are made from impact-resistant PVC, meet
the stipulations of the British and European standard for the
design requirements for render beads (BS EN 13914-1:2016),
come in a range of colours and will never rust.
Renderplas was the UK’s first manufacturer of PVC beads for the
rendering, plastering and dry lining industries, and is recognised
as the authority in the field.

meant we could create a perfect pinstripe between the K Rend
Limestone White and Granite render at the bottom of the wall,
which looked great.”
