PVC Movement Joint/ Expansion Joint Beads - Movement Joint for Rendering/ Plastering

Polyvinyl chloride (PVC) movement joints/ expansion joint beads for rendering and plastering.

Features and benefits:

• Designed to provide function and speed on all external and internal rendering and plastering applications.
• Gives a good finish to every type of render, including through colour render.
• Can be used horizontally as a day joint to disguise a break in the application of render, and provide an attractive architectural detail with a gentle shadow.
• Available in white and ivory across all PVC bead profiles (except MJ4, which is supplied in white only. Available in slate and dove for MJ10 and MJ15).
• Manufactured from recycled, exterior grade, impact resistant, UV stable PVC, providing a cost effective alternative to stainless steel beads.
• Will not to stain or corrode (like with galvanized steel beads), reducing spalling and impact damage.
• Reduced installation time.
• Not affected by severe weather conditions; the flexible plastic membrane provides a watertight seal, 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 in the same way as render.
• Suitable for all habitable climates.
• The chemical bond between flexible and rigid parts prevents separation.
• Fit for purpose for the lifetime of the render; at least 25 years.

Performance/ Approvals:

• 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.
• Exceeds the British Standard for thermal movement BS EN 13658-2: 2005. The flexible plastic membrane gives a certified range of ± 2.5 mm. Protective tear off strip allows quick removal of render from the joint.
