The ducts IM ® is a panel of pure embossed aluminium pre-insulated with a Polyisocyanurate (IM) foam and used in the construction of ducting for air distribution in heating, ventilation and air-conditioning systems (HVAC). With these IM® pre-insulated panels an extremely high quality ducting can be achieved, as a direct result of the combination of the aluminium and of excellent insulation (IM). This combination also provides and excellent internal air quality (IAQ), a fine external finish, long life material, lightweight and easily transported, manipulated and constructed.

The panels: Panel of aluminium embossed pre-insulated with IM foam Size: 3.000 x 1.200mm Thickness: 20 or 30mm Thermal insulation: K=0,020 Reaction fire: CLASS 0 (BS 476)

Base of the system 1º Size of the panels: 3.000x1.200x20mm

Base of the IM system 2º Cut of the longitudinal strips at 45º

Base of the system 3º Ducts assembled with four separate faces.

Base of the system Lengthwise glued, Aluminium tape Glue Silicon Lengthwise glued, Aluminium tape in trhe external longitudinals angles, Silicon in the longitudinal internal angles.
