Prefabricated walls for exteriors with dry system

The Jendy Joss® external prefabricated dry walls are a modern and efficient solution for long-lasting, sustainable construction. Designed for maximum performance efficiency, the JJ Module guarantees maximum reliability thanks to important technical characteristics:

  • Excellent air, water and wind resistance
  • Excellent acoustic performance, with certified insulation of up to 62 dB and guaranteed by the imprint of an internal wall
  • Fire resistance certified EI120, according to UNI EN 1364, with interfloor sealing, ideal for meeting the highest standards of fire safety.

In addition, the CE marking, compliant with UNI EN 13830, certifies the safety and quality of the product.

The Modulo JJ allows maximum customization in the finishing of the facades, so as to meet the different needs of architectural projects. The external finishes may include:

  • Plastering and painting: done directly in the site.
  • Ventilated facade: with high quality materials for a modern and functional design.
  • Armed plastering and painting: applied in the factory, with only sealing of joints carried out on site.

“Cell facade” system

Our prefabricated solutions allow the positioning outside the structural wire with a “cell facade” system based on extruded aluminium elements; the MODULES are then “hung” with special brackets prepared in the ceiling, with vertical adjustment. Each JJ MODULE connects perfectly to the adjacent modules, both upper/lower and lateral, so as to guarantee continuity and stability to the facade.
