Need a hose on the air ducts ?

The air distribution ducts or ductwork or pipes or vent tube are conduits for circulating air from point A to point B.

A ventilation duct  allows the circulation of air and the evacuation outwardly. Discover the benefits of flexible ventilation ducts or semi rigid with Culture Indoor leader of the ventilation duct in France and Europe factory direct manufacturer.

Ventilations ducts are essential for the installation of extractor s or air vents for the bathrooms, the VMC from home or office, air conditioning ducts specific, usually conducted in cotton wool is used.

Discover the different ducts or conduits of breakdowns and their technical characteristics.

Types of ducts and ducts

Here are the different types of ducts or ventilation ducts:

• Sheath or conduit made of galvanized steel,
• Duct or conduit made of flexible aluminum,
• Sheath or conduit in semi-rigid aluminum,
• Duct or duct made of flexible synthetic material of pvc type or double layer aluminum, pvc,
• Flexible ventilation ducts or ducts or glass wool,
• Flexible flexible ventilation ducts or air ducts or glass wool,

The cylindrical ventilation ducts are called ventilation ducts.

Flexible ventilation ducts are lighter and more economical.

Flexible ducts are easy and quick to install.

Flexible ducts are perfectly suited to changes of direction in plan and elevation, perfect to create turns or make waves to pass above, to pass the obstacles in the false ceilings easily and easily.

Sealing flexible ventilation is very good, especially if the connections between pipes is made with seal, use eg  raccordemen cuffs t to obtain a perfect seal between the connections of pipes or ducts.

Insulation conduits and their advantages

The insulation of the duct is directly integrated.

Flexible or semi-rigid ducts

Flexible ducts are not recommended because they cause significant pressure drops compared to rigid ducts but more often used by their simplicity of installation and their reduced cost.

The advantages of flexible ventilation ducts and ducts

They are useful for difficult fittings at the mouths or other devices.

The vibrations and noise from the air movement are more easily absorbed making it interesting conduits for achieving higher acoustic performance.

Flexible ducts cause greater pressure drops than a rigid or semi-rigid duct.

Due to the material used, this type of conduit is generally fragile, which does not facilitate its cleaning.

If the inside of the duct is not smooth, the fouling will be more important.

The shape of the elbows, changes in direction, section or bypasses play an important role in the various possible head losses in the distribution network. Find in our elbows rays at 30 °, 45 °, 60 °, 90 °, T, Y , junctions,  headlines connections, clamping collars,  the flanges, wall connections etc ...

Thermal insulation with insulated thermal insulation

In the case of ventilation in a cupboard, for example, it is useful to isolate the ventilation ducts between the ventilation unit and the outside, whether the ventilation duct is located inside or outside Of the protected volume. This to limit heat losses, and thus ensure maximum recovery, and the risk of condensation that will prevent you from micro droplets all over the inside, condensation must be controlled.

To limit heat losses when the ventilation duct of hot air or cold air, there are ventilation ducts or ventilation ducts that are thermally insulated like the sound duct.

In the case of  thermal ventilation ducts joints shall close by means of tape adhesive .

The ducts are generally composed of mineral wool boards, rock wool, discover  Winflex Ventilation and its thermal jacket with natural wool is itch , finished wool scratching you during and after your installation in ceilings or For example.

Ventilation duct with sound insulation.

A ventilation system is a source of noise with sometimes significant noise. The acoustic nuisance is mainly due to the operation of the fan and the air movement in the ducts, so what you hear is the wind in the ventilation duct directly and it is the noisiest.

In order to avoid the noise nuisance of your ventilation ducts and to limit the sound there are various possible solutions to solve your sound problem:

• Acoustically isolating ducts reduces noise radiation in rooms.
• Use anti vibration supports for ventilation unit limits the propagation of structural noise discover this to soundproof boxes SOFTBOX including an extractor suspended on rubber springs allowing a perfect isolation of engine vibration of the air extractor.

Designing a barrier-free air distribution system:

1. Reduces turbulence and therefore sources of noise,
2. Limit and vary the speed of air in the ventilation ducts,
3. Arrange the ventilation air extractor in a location away from living or working rooms,
4. Air tightness in ventilation ducts: The ductwork must be airtight to minimize air leakage in order to guarantee the defined air flow rates,
5. Avoid sources of additional noise,
6. Protect against additional fouling or condensation in your ventilation ducts,
