Frame (single/double): Double
Thickness (mm): 55 mm
Weight (kg/m2): 22,0
Thermal trasmittance on 30cm brick (W/m2K): 0,169
Thermal periodic trasmittance on 30cm brick (W/m2K): 0,015

External Insulation on existent wall with Jendy Joss® thermal-acoustic high-performance dry system composed from a double wood frame, cover with calcium-silicate boards and thermoreflex thin insulation material, for total thicknes 55mm (excluded external finishing), with linear thermal transmittance U=0.169 W/mqK, periodic thermal transmittance Yi.e=0.015 W/mqK, thermal attenuation factor 0.087 and summer thermal lag 13h 16’ (thermal valutation considering an existent brick plastered wall of thickness 30cm and excluding the finishing). The wall is ready for shaving and painting, coating or the ventilated facade.
The wood frame consists of a double vertical profiles size 20/50/20mm, with distance 400mm, fixed to existing structure through appropriate dowels. For thermal insulation in the middle of double wood frame i twill be applied a thermoreflex thin insulation material with high thermal performance like 190mm of mineral wool with thermal conductivity λ=0,040 W/mK. The exterior side is closed with calcium silicate board UR12 with thickness 12mm, screwed to the wood by special screws VT4.0*45. All Universal Rock® calcium-silicate boards have a high density of 1,200 kg/m³ and high mechanical performance, in A1 Fire Class Reaction, with universal use, with absolutely no harmful materials and have a very low Radioactivity Index of 0.15.
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. Including thermal bridging treatments.
Empty for full <4.00mq.
