2. 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.

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