JENDY JOSS “PREASSEMBLED” EXTERNAL WALLS WITH MODULO JJ ARE THE BEST SOLUTION TO GET THE HIGHEST THERMAL-ACOUSTIC INSULATION FEATURES WITH VERY REDUCED THICKNESS AND WEIGHT, ECO-FRIENDLY MATERIALS WITH EXECUTIVE QUALITY BENEFITS AND SPEED.
The proposed solutions are realized through a single galvanized steel frame with increased thickness 12/10mm or what result from static calculation, distanced 600mm with one in two vertical profile double.
Inside every MODULO JJ it’s inserted in factory the mineral wool insulation material for best thermal-acoustic performances; the module it’s closed on both sides with high density calcium-silicate boards Universal Rock which gives very high mechanical resistance features.
The thermal transmittance values for the proposed solutions are 0,140 and 0,168 W/mqK and the facade acoustic insulation is ≥60 dB.
Every module has an “interpenetration system” for fastening to adjacent module with special screws VT4.2*32, galvanized and self-tapping. The wall is positioned outside structural line for eliminate the thermal bridges, the fastening to beam and pillar is variable and to be specifically considered every time.
For interior finishing it can be applied a 13mm plasterboard coupled with 30mm rockwool panel or an interior false wall, than completed with a traditional joints shaving to obtain a surface ready for sanding and painting.
For the external surface, in the case of shaving and painting, the 4mm external joints between the UR12 calciumsilicate boards will be filled with specifical product and inside fiberglass net of 165 gr/mq and width 5 cm.
In case of ventilated facade it will be applied a 110 gr/mq black vapor barrier with waterproof function also during the construction time and dark background in case of facade with opened joints.
It’s possible to elaborate specific solutions for all different applications.
EXTERNAL WALL WITH DOUBLE FRAME – THICKNESS: ≥ 315 mm
EXTERNAL WALL WITH SINGLE FRAME – THICKNESS: 247 mm
