Designers are often keen to select their own TBV system,
however, the selection process involves many factors, so we would
prefer to assist you in your selection.
- In order to determine what type of textile ducting solution is suitable
for your application, we will need to know a few things;
- Dimensions of the space
- The intended use of the space - from this we will calculate
suitable air velocities for the occupants based on required comfort
- Permissible locations to run the textile ductwork
- Supply air volume
- Maximum and minimum supply temperatures and the desired room
- The required NR rating of the space
- What type of surface we are able to mount to
Winvent3D, our inhouse design program needs all of this
information to provide a quotation, we prefer not to quote per
In order to dimension a textile based ventilation system,
it is important to understand a number of essential parameters and
concepts. A textile based ventilation system is not that different
from conventional ventilation systems, but there are a number of
key points where it is important to be extra cautious, such as
pressure conditions, pressure loss, pulsations, pressure impact,
entrainment, air velocities and sound.
It is immediately obvious when a textile based ventilation
system has been dimensioned incorrectly because the ducts will be
oval and "saggy" when you look at them. The difference in the
static pressure between two parallel ducts could be quite
considerable too. This not only has an impact on the look of the
system, but also on the air distribution. If the pressure
distribution is uneven it could cause draught problems
below and around the duct with the highest static pressure, while
in another area, the air quality will be poor where the static
pressure (and therefore the volume of air) is insufficient.
Furthermore, there may be a risk of pulsations in the textile
material that may damage not only the textile material but also the
Finally, a correctly dimensioned TBV system is important so as
to achieve the required sound levels from the system.

Dialogue & Quotations
KE Fibertec has developed a number of tools and services
that our customers can choose to use throughout the entire project
process. Our services are graded so that customers can decide
themselves which ones they require. We believe that no two
jobs are the same and no solution is standard. As a result, the
documentation and level of detail needs to be adapted to the
requirement and each individual project.
Our service can be split into two categories:
- Quotation and design
- Exteneded project documentation
Our quotation and design processes are described in detail
in our ISO 9001 quality assurance system. This ensures that we
prepare the basis for the quotation and the quotation itself
according to the standardised guidelines, while making sure that
the customer's requirements are specified and documented in
KE Fibertec puts a large emphasis on ensuring that the final
solution is designed correctly even at the initial quotation stage.
After all, it is not only about ensuring that the textile based
ventilation system works properly, but also, just as importantly,
that the customer's requirements have been met. This is why we ask
about the system's functional requirements and the requirements for
the indoor climate even at the quotation stage. We do not make
a habit of selling textile ducting by the metre.
All our calculations are proven using our unique
software WinVent 3D, this is offered to all our customers,
regardless of the size of their project and, of course, it is free
Detailed mounting and maintenance instructions are included.
For more complicated TBV systems we also include AutoCAD
As part of our extended project documentation we can offer
full-scale measurements in our laboratory, on-site
measurements and CFD simulations.
