Efficient thermal destratification is a prerequisite for a pleasant indoor environment. When dispersing air through conventional metal ducting this is difficult to achieve, as the technological shortcomings result in stale air, coupled with hot or cold spots. Switching to fabric-based air dispersion technology efficiently solved this challenge.

Stratification, also known as layering of differing air, happens in any space if not specifically countered. The temperature increases from floor to ceiling, because cold air is heavier than hot air.

Typically, there's a temperature difference of up to 1,5°C per vertical foot. The higher the ceiling, the more extreme the temperature difference between floor and ceiling. In between the two, the air settles in layers. Destratification is the reversal of this process.

FabricAir dispersion technology offers unrivalled destratification, with a low temperature gradient across the space being conditioned. This is the result of a fully flexible air engineering design scheme that covers profiles, fabrics types, flow models and suspension solutions.


Using engineered airflows to mix the internal air eliminates layers of hot, cold and/or stale air and ensures temperature equalization throughout the space – a process known a thermal destratification.

Even air dispersion without unpleasant drafts creates the best indoor environment and efficient temperature equalization is an important aspect.

There are a large number of factors that influence the optimal design for a specific project or application, e.g. the number of people, the processes that happen in the space, the HVAC specifications, the location of supply and return air, solar gains and insulation against outside weather conditions, etc. This is why selecting a flexible and versatile technology is crucial to achieving efficient thermal destratification.

Using a combination of flow models the air engineer designs the best air flow patterns for the given space and purpose. Typically the ideal solution contains a mix of surface flow models and directional throws. A high air change at low velocity will in many cases be preferred in order to achieve optimum comfort and a draft-free work environment. CFD is often used to verify the efficiency of the solution, especially in more complex applications.

The customised FabricAir dispersion system is tailored to specifications and arrives onsite only two weeks after the order is released for production. It arrives ready for installation and there is no need for onsite attenuation, insulation, painting and so forth. Coupled with ease of transportation and simple installation process it amounts to up to 70% savings on total installed costs.

The precision airflow patterns and efficient thermal destratification also make FabricAir dispersion solutions a more energy-friendly alternative. Up to 40% savings can be achieve by simply switching from metal-based ducting to FabricAir ducting.

This is why fabric-based air dispersion technology is the most efficient way to achieve efficient thermal destratification.
