JDV 4.04 Vertical expansion joint under plaster

JDV 4.04 joint specifications

The JDV 4.04 is an expansion joint under plaster or façade rendering and can be installed either flat or at an angle. Both models are available on our technical data sheet. It is economical, practical and easy to install. This vertical expansion joint is available for 30 and 50mm openings (other width available upon request). Several heights are available: 11, 14 and 20mm. Furthermore, the nitrile insert is available in different colors: black, grey or creamy white. This expansion joint with insert is available in 3lm lengths.

How to install an expansion joint under plaster?

JDV 4.04 thermoplastic polymer or galvanized steel expansion joints should be installed at temperatures between +5° and +40°.

1. Check that the expansion joint is dry, clean and free of grease.
2. Glue the expansion joint using a bonding agent or coating suited to the substrate and metal fins.
3. If necessary, fix the expansion joint with insert using VB-TF 6.6×60 concrete screws.
4. Thermally weld the nitrile inserts together to ensure a proper connection between lengths.
5. Protect the insert with adhesive tape to avoid clogging when spraying plaster.
6. Apply sprayed plaster to facade, wall or ceiling.
7. Smooth surfaces.
8. Remove tape from nitrile insert.
9. The under-plaster expansion joint is now installed. Please protect it during the construction phase.

The coating is not supplied by Veda France.

Why use an expansion joint?

Buildings undergo movement throughout their lifetime. The origins of these movements are varied: shrinkage of concrete, expansion and contraction of structures, settlement of the structure, movements generated by the environment (trains, planes, wind, rain, etc.), earthquakes. Expansion joints must be created to maintain the durability of a large-scale construction over time. This is an empty space, free of any material, between two parts of a structure. They run the full height of the structure, allowing each element to move freely to avoid colliding. It is dimensioned according to the possible deformations of the construction. Whether standard or earthquake-resistant, an expansion joint must allow for horizontal, vertical and/or shear movements. In the case of our JDV 4.04 steel expansion joint, the movements absorbed are multidirectional.

Expansion joints on walls and facades

The vertical expansion joint is fixed to the entire height of the building. We offer a wide range of expansion joints to meet all your requirements: seismic or standard expansion joints, galvanised steel or aluminum expansion joints with insert or without, for small or large openings, expansion joint under plaster, embedded or surface mounted, etc. All our facade and wall expansion joints are perfectly compatible with our range of firestop joints: VEDAFEU C firestop cords.
