ROCKAL flexible ducts are fully flexible high quality thermally insulated ducts for various purposes.
ROCKAL flexible ducts are fully flexible high quality thermally insulated ducts for various purposes. The ducts consist of an ROCKAL inner core shielding the fiberglass insulation from the airstream with a tough outer jacket/ vapor barrier constructed of multiple layers of aluminum laminated construction and reinforced with fiberglass. The ducts are easily installed over either round or oval connection. The ducts are manufactured according to the international standard EN 13180.
Rockal Flexible ducts are used in heating, ventilation and air conditioning (HVAC) to deliver and remove air.
Minimum Bending Radius: 0.58 x Ø
Working Pressure: Max. 300mm WG (3000 Pa. or 10-inch WG).
Rockwool blanket insulation is a type of flexible insulation made from spun mineral wool, which is derived from a mixture of volcanic rock and slag. Rockwool Rolls are high performance solution for thermal & acoustic insulation for a range of commercial and industrial Buildings.
