The Sonosystem flexible ducts are insulated flexible ducts made of light laminate for a wide range of applications. The Sonosystem flexible ducts consist of a perforated inner hose, 25 mm thick fiberglass insulation and an outer envelope. The Sonosystem insulated hose is suitable for ventilation and air conditioning systems without special requirements, to prevent water condensation and to reduce noise levels in HVAC systems. It is not suitable for flue gas extraction from open fire chambres, oil boilers and for air distribution with a high concentration of acids or hydroxides.

Sonoflex are flexible Al laminate hoses with an internal arrangement such as Aluflex MI or MO. The flexible Sonoflex hose has thermal and noise insulation made of a layer of mineral wool 25 mm thick (16 kg/m3). The inner hose is perforated as a silencer. The construction contains a vapour barrier to prevent condensation in the noise insulation.
Sonoflex are flexible ducts (hoses) suitable for reducing noise in ventilation systems, air conditioners and heat pumps. The standard length of the sound and heat-insulated Sonoflex hose in a package is 10 m compressed to 0.5 m  The temperature resistance of Sonoflex MI from -30 to 150 °C and Sonoflex MO from -30 to 250 °C.

Termoflex are flexible Al laminate hoses with an internal arrangement such as Aluflex Mi. The Termoflex flexible hoses have thermal insulation made of a layer of mineral wool 25 mm thick (16 kg/m3). The construction contains a vapour barrier to prevent condensation.

Termoflex are flexible ducts (hoses) suitable for reducing condensation and heat losses in ventilation systems, air conditioners and heat pumps. The standard length of the thermally insulated Termoflex hose in a package is 10 m compressed to 0.5 m. Temperature resistance of Termoflex MI from -30 to 150 °C and of Termoflex MO from -30 to 250 °C.

Termoflex Hygienic are flexible Al laminate hoses with a steel wire frame, spirally wound between two layers of multilayer Al laminate. The Termoflex Hygienic flexible hoses have thermal insulation of a layer of mineral wool 25 or 50 mm thick (16/14 kg/m3). The construction includes a vapour barrier to prevent condensation. The Termoflex Hygienic are hoses designed for applications where high demands are placed on hygiene of environment and it is not possible to perform regular inspections of air ducts. The Termoflex Hygienic is a flexible duct (hose) suitable for reducing condensation and heat loss in ventilation and air-conditioning systems and heat pumps. At the same time, their use is suitable for air distribution in conjunction with heat recovery units. Standard length in package 10 m compressed to 1.2 m.

Aluflex are flexible Al laminate hoses with a steel wire frame, spirally wound between two layers of a multilayer Al laminate. The Aluflex flexible hoses are designed for ventilation systems, air conditioners and heat pumps. Standard package length 10 m compressed to 0.5 m. Temperature resistance Aluflex MI is from -30 to 150 °C and Aluflex MO from -30 to 250 °C.

Aluflex Hygienic are very durable, flexible and microbially treated Al hoses with a steel wire frame, spirally wound between two layers of multilayer AL laminate. The hygienic flexible hoses are designed for applications where hygiene of environment is required and it is not possible to perform regular inspections of air ducts. Aluflex Hygienic flexible hoses are suitable for air distribution in conjunction with heat recovery units.

Greyflex are flexible hoses made of two layers of PVC with polyamide fabric, reinforced with a spirally wound steel wire frame. The Greyflex flexible hoses are designed for mechanical ventilation and air conditioning ducts, for dust and smoke extraction. The hoses are highly mechanically resistant, supplied in grey. The standard length in the package is 10 m compressed to 1.15 m.

The Kombiflex flexible hoses** are made of a layer of PVC with polyamide fabric on the upper side and Al laminate on the inner side, reinforced with a spirally wound steel wire frame. The Kombiflex flexible hoses are mechanically resistant, suitable for smoke and dust extraction. Standard length in a package 10 m. Operating temperature -30 to +150 ˚C, maximal air flow speed in the duct 30 m/s.
